Multiplication Timed Test 0 12: Fill & Download for Free

YupI cleared the same way back in 2012 when it used to be AIEEE with 228 marks and all India rank 7109 in 3 months of serious preparation before the exam. Here serious preparation means around 10 hours of DEDICATED STUDY each day.Now the first suggestion is DON'T PANIC. You will not gain anything if you are going to continue this mess further.Secondly, from now onwards you have to work very hard. You have to give at least 10 to 12 hours each day on preparation.Lastly, you have to limit your study resources to a bare minimum.Now a broad strategy is to get Xerox notes of any coaching institute. Since I did my coaching from resonance so for me it was resonance's notes. Here I want to clarify one thing; although I did attend coaching I was hardly regular. I often skipped classes. So for me, the net result from coaching was zero. Ultimately I also had to rely on Xerox notes.NextYour priority inter se subjects should beChemistryMathsPhysicsIn chemistry, if you know the things then you are going to get marks with least effort and least time. Further, that saved time can be utilized in other subjects. So Cost-Benefit is excellent.Now inter se priority among chemistry should beInorganic ChemistryOrganic ChemistryPhysical Chemistry.INORGANIC CHEMISTRYHere you have to read NCERTs multiple times; multiple times mean 3–4 times at least and if time permits then do a revision. It took me around 25 days giving 4–5 hours each day.Also, a 4 page note was provided by resonance regarding qualitative analysis. This was an excellent one. If it is still there I don't know. But if you can find it do it otherwise do it selectively from any coaching notes.ORGANIC CHEMISTRYGet notes of MM sir from any friend who is studying in resonance. His notes are laconic, succinct and to the point. You can cover it in 15-20 days giving 4 hours each day. I didn't do anything but his notes during my preparation days.PHYSICAL CHEMISTRYThis was my Achilles heel. You can't do physical in a very short time given the fact that thermodynamics, Ionic equilibrium and Electrochemistry are very vast.So you should first concentrate on high return topics like Chemical bonding, chemical kinetics, basics of mole concept and various definitions involved therein like normality, molarity, molality etc. …Atomic structure…chemical equilibrium….solid, gas and liquid state and other such topics. I did these in a way that after reading notes I solved few questions of LEVEL 1 of sheets provided by coaching. That's it.For rest of the topics have a quick reading of NCERT so that at least you can solve easy theory questions, further remember formulae and in every formula what each term signifies…..their signs etc…..since in JEE MAIN’S chemistry mostly they ask formula-based questions involving at max two formula.It ate up 30 days of mine, giving 4 hours each day.MATHEMATICSIn mathematics, if possible; the first thing to do is to look for objective approach especially in trigonometry, quadratic equation, sequence series, coordinate geometry, matrices among others. For example in coordinate geometry, you can remember a master triangle their vertices, midpoints of each side, orthocenter, circumcenter etc etc and apply them in a given question. You can remember a master 3×3 matrice….inverse of that matrix…..its multiplication with itself….its inverse….and then apply it in any questionNow focus on those chapters in which questions are such that their way of solving is largely fixed; that is they are METHODICAL. Few of them are.Quadratic equationCoordinate GeometryVectors3-DLimits and continuityFunctionsMaxima Minima, Rolle’s theorem, LMVT etc etcDifferential EquationMatrices problems like the solution of a system of equationsA large part of sequence and seriesDefinite Integration and Area under the curveA major part of trigonometry although most of them can be solved by the objective approach.Etc. EtcHere you should avoid wasting much time on any topic ie. You should avoid doing PhD in any of these topics. just do at par questions of previous JEE MAIN and AIEEE paperAfter that, you can selectively do unpredictable topics like PnC, Probability, complex numbers, Indefinite Integral etc etcI gave around 40 days to Maths averaging each day 6 hours.PHYSICSHave a basic idea of Newton's law of motion, master Free body diagram even if it takes 4–5 days.Now concentrate first on topics which are largely formula based …once you understood the essence of formula you are ready to roll. Few of them areHeat and ThermodynamicsOpticsModern physicsSHM and waves.Fringe topics like viscosity, elasticity, heat transfer, surface tension, expansion etcPractical topics like Vernier calliper, pendulum, screw gauge, unit and dimension etcAforesaid should be very high on your priority. These are the topics where you can get a good amount of marks with least effort.After that concentrate onCurrent ElectricityCapacitorsGravitationElectrostaticsCenter of massFluid MechanicsMotion including circular motionAt last move to tough topics likeRigid Body DynamicsElectricity and MagnetismHere also key is that apart from the 1st set of topics don't delve much deeper in other topics. Just read notes and solve few level 1 questions of coaching sheet.I gave almost 50 days on Physics …each day around 4 hourRevision is sine qua non….90 minutes each day should be devoted exclusively for revision.You should skip any test series given your preparation level. Just give one or two mocks in the last week before the exam so that to calibrate your preparation and to know your limits in time constraints.Be positive and have faith in yourself.EDIT- All the above strategies were followed by me without any kind of Board Exam pressure in class 13th ie. one year after board exams. So I might not be the correct person to tell you strategy with simultaneous preparation for the board. Plz, keep this into consideration.

This was my Second Attempt. I cleared very close to the margin. (Cleared CSE Prelims but not IFoS Prelims).Lessons Learnt :Lesson 1 : Give as many Tests as you can (without compromising on your exam reading).Tests helps you to find your optimum attempt. For me it was 95+.This year CSE Prelims I attempted 100.Don’t get me wrong. For some of us the optimum may be 65 or 85. And this may change depending on the level of the papers.In 40+ tests I gave, only in 2 tests I got negatives for attempting those questions in which I could not eliminate any of the four options with full confidence. And the negative score was marginal : out of ~10 such questions attempted, the aggregate score for these 10 questions was > -2.Giving tests in the last one month is also important. I did NOT practice enough in the last one month. I marked atleast 2 questions wrong (eg. Hepatitis B) due to mental exhaustion.Tests help you to develop your intution. Take chances and see where you went wrong and why. You will see a significant jump in your score after about 5 tests.Lesson 2 : Don’t ignore NCERTs.I marked some questions wrong (eg. Kalyan Mandap) which were asked directly from NCERTs.Lesson 3 : Regarding Current Affairs.Do atleast 20 months current affairs from multiple sources.Here I followed the strategy of Archit Chandak IPS.I followed Vision IAS Monthly and Insights Daily Quiz besides Indian Express.I made Prelims specific notes (from sources mentioned in point 3) and revised them multiple times. ( I have a relatively weak memory).If you do Monthly booklets; then Vision PT 365 for Polity, Economy is frankly of no use. For Art and Culture, and Environment refer to previous years PT 365 as well.Lesson 4 : Regarding CSATDon’t ignore at any cost.Last year my CSAT score was >160. This year I didn’t had the heart to match my answers with answer keys.But fortunately I cleared.Lesson 5 : Don’t heed to Rumors.No coaching institute can claim 100% knowledge of Cutoffs.Most of their answer keys are wrong.Lesson 6 : Toppers’ advice.Take toppers’ advice with caution.Toppers who cleared before 2018, may not in a position to give the right advice for prelims.Post 2017, the difficulty level has gone up considerably.Lastly, one example where giving more test helps :CSE Prelims 2019 Question 33 Set A :I only know that Madhya Pradesh is the number one state in India in terms of Total Forest Cover (Biennial Forest Survey of India 2017–18, well covered by every major newspaper and current affairs monthly). But this information alone is not sufficient to answer this question.I was about to give up on the question. But here solving mock test papers help.MP and Maharashtra looks almost the same size on India’s Map.So if MP is no. 1 in total forest cover then it logically follows that it has more forest cover than Mahrashtra.If both have almost the same area, in terms of percentage, MP should have more forest cover than Mahrashtra.This straight away, helps you to eliminate a and b.Now regarding Orissa and Chattishgarh.From the ongoing elections (2019 Orissa State elections and the 2018–19 State elections in Chattishgarh ), I know that Orissa has almost double the number of MLAs than Chattishgarh.Orissa does not look twice as big as Chattishgarh on map.Both states have similar developmental levels (both mineral rich eastern states), the populations density (of habitable/habitation areas) may almost be the same.Orissa has almost twice the number of people than Chattishgarh (follows from point 6) , but the area of Orissa though bigger than Chattishgarh does not appears to be twice as big. Hence, though both have similar population density (of habitable/habitation areas point 8), the relative sizes of the two states does not justifies the relative difference in populations.As both States are located in the Central Forests belt of India, it seems that the reason for such a disparity (point 9), may be that Chattishgarh have more forest cover in % terms than Orissa.After point 4, a well read CSE aspirant could have straightaway taken the guess that Chattishgarh (known for high frequency of naxal related incidents, land locked state) may have more forests than Orissa (in % terms).Hence the answer is C. +2 in a question which I was about to leave thinking I don’t know enough.Note 1 : Here I could not deduce whether Chattishgarh has more forest area in % terms than MP, but it doesn’t matter. The options are so made that I can see after solving the question that Chattishgarh has more area in % terms than MP.Note 2 : Here it may look that I took a long time figuring this one out. But when you actually think about it in the exam hall it took me 1 to 2 minutes to solve this. (Not much considering that this was a medium level question and some easy questions take less than half a minute. So you can compensate for the time).Note 3 : Though I got this right but this was still a guess, specially after point 4. Hence while doing a test series I would consider this the question of the type in which I could eliminate only 2 options.An example of how I gave test series and calculated my segregated score.Last two columns E 0 and E 0 R represents those questions in which I could not eliminate any of the four options with full confidence. I attempted these with some intution or due to partial knowledge of some options.I marked 27 such questions in this particular test and got only 9 right. But my overall score +6 was still positive. This can be brought up considerably with more practice and more analysis of the way you attempt questions.However, I must admit that every successful candidate has his own unique strategy, I have seen some toppers’ talk in which some toppers say that they attempted 60–70 questions only. While some like Siddarth Jain, Archit Chandak, Tushar Gupta maximised their attempts. I followed the latter as it suits me well.Edit 1 : For those asking for Spreadsheet : tests2018-19).xlsx see after test 17.Edit 2 : I cleared the 2019 prelims cutoff by a whisker. My score for 2019 prelims was 98.66. General cutoff for UPSC CSE Prelims 2019 was 98.

Short Answer: Not up to the mark, bad platform, unbalanced problemsetAbout Me: I was a member of the team Pandora's Illusion which finished 8th and solved 8 problems (A, B, C, E, F, H, I, J)This was my second regional at the Amrita University Coimbatore campus.The ContestThere were four major issues with the contest. I will list them below:Platform: The platform used, HackerRank, was very bad. I am sure they worked hard and everything, but when each and every online round had issues, the practice round had issues, I didn't see any sense in continuing with that platform. Probably the Amrita folks saw sense through the sponsorship (so I hear) which HackerRank gave. The contest was so slow. We had coded the first three problems (F, I, J) within the first 20 minutes but could only submit them at minutes (47, 13, 57) (EDIT: we couldn't submit because the submit section at the bottom of the page wasn't loading). If you are familiar with icpc styled contests, you would know how the penalties stack up. If you solve a problem at minute X, you get X penalty. And some of you would say that we should have moved on to the next problems but it is tough to do that when you have THREE problems coded up and you are waiting for the results on all of them. We started solving the better problems only after the first hour and that added up so much penalty. On top of that, volunteers and amrita people kept coming and disturbing us every two minutes asking if the system was working fine or doing something on our computers, refreshing hackerrank (though they were only trying to help us, they were of no help to us). When you have solved the same number of problems as the team which came first and you are eighth just because of penalty, it sucks balls. If we remove 30 min penalty from seven problems (since we did manage to submit one at minute 13), we would have been 6th at the least (and perhaps could have qualified for the finals), not to mention would have had another half hour to solve more problems. Though, it is wrong of me to take credit from other teams as they also might have faced similar problems, but from my interaction with some other top teams, none of them had so much delay (there was at least one more team with issues as grave as ours, but they only solved 4 problems, so it didn't really matter that much to them). HackerRank has a wonderful platform but they really screwed up this time. I really do not understand why does amrita keep increasing the number of teams on the onsite. 410 teams is just too much! 200-250 would have been more than enough. In the practice contest as well, they only had two questions and I don't think they were able to test the server capacity properly.(EDIT: HackerRank - It's was the worst experience of any contest... another team had similar (or even worse) issues)Problemset: The problem set had good problems if you look at each problem individually, but as a problem set, not good at all. There were some cakewalk problems, a couple of easy mediums and some reheheheally hard problems. There were no "medium-hard" problems which could have brought some gradient to the ranklist. Top 12 teams all solved the same number of problems (8). Ideally, top 1-2 should solve some x problems, 3-5 x-1, 5-10 x-2 and so on. Have some distinction amongst the top few teams at least! I can understand if there are 40-50 teams solving 5 problems or so, but at the top at least there should be some gradient. But, it is tough to gauge the difficulty of a problem set and luckily none of the problems (at least the solved ones) had any issues.At the start: So, we were logged into the contest arena, and the countdown was going on. 17-16-15s when suddenly this guy comes and asks us to turn off the monitor o.0 saying that there will be an announcement. There was no announcement, and we weren't given the problem set until 5 minutes after the contest had started. The contest started on time at the other two sites and we were chilling out in Coimbatore with our monitors off and no problemset, waiting for the announcement. We randomly turned the monitor on, and saw everything was up and had started. We made some noise and finally were given the problemset. I mean, wtf. In the end, the contest was extended by 5 minutes -_- which was of no help to us since we ended up solving maximum number of problems with over an hour to spare.Afterwards: They called the top 15 teams to the stage for giving them mementos, and gave "PARTICIPATION CERTIFICATES" which is very wrong. Even the memento has no mention that it is given for "merit" or something. It just says amritapuri regionals bla bla bla. We didn't have any official proof that we were 8th.The problemsI will give a quick feedback on each problem (the problems aren't up yet and I will add the links as soon as I can find them):(EDIT: The problemset is available at: Page on Amrita)A: Binary search on quiver capactiy and check feasibility in O(m) time. Total complexity O(mlogm). The simple and obvious solution seemed like it would TLE as the same arrow could be in the queue multiple times and people discarded this solution and implemented a priority queue making the solution O(mlogm * logn), but if you did amortized analysis, you would realise that even though the same arrow could be in the queue multiple times, there can only be O(m) queue operations.B: Simple DP. complexity O(n). You needed to keep find the answer for two states at each step, whether the current elements have been swapped or not.C: Sliding window, complexity O(nlogn) (since you had to sort the input). Slightly painful to code since there are boundary cases and all which sometimes get a little tough to visualise.D: Didn't solve. We kind of proved that team A could win iff there existed a perfect matching. After that we had some ideas, but nothing concrete. No team solved this problem.E: Counting using DP. You had to pre calculate all the ways to color a 2xn board using EXACTLY m colours with the given constraints before hand and then use that to calculate the final answer. O(m) for each test case and 10^6 precalculation.F: TrivialG: Had some ideas, but they were all wrong. After the contest thought about calculating the number of paths between every two vertices and then use some sort of inclusion-exclusion principle to calculate the answer. This turned out to be the correct solution.H: Simple BFS, made such stupid mistakes while coding it and got two WAs on it as well. Mark all the (*) cells and once they have been seen twice, put them in the queue.I: Trivial. n <= 3, print n, if odd print 4, if even print 3.J: Two equilateral triangles and you can put them any way you want, find the minimum area of the rectangle which can cover them both. Two cases. Just draw and see. Very simple to figure out.K: Painful painful painful problem. Math. Required too much calculation, didn't try it.Not so important stuff: No locks were given and we weren't told about this. We had to buy Rs.160 locks as they were the only ones available in the campus. Teams weren't given the same room, though in the end most teams shifted and adjusted with each other.It could have been a good contest for us if HackerRank hadn't screwed up so much initially. The problems were definitely better than the Kanpur regionals but not by much.
