Unit 7 Chemical Formulas R: Fill & Download for Free

Yes, why not. Anything is possible if you have the will and determination to work hard.But, why would you target for 95 percentile as with that percentile you won't get a good college. Anyways, since you have asked the question, I am providing some information in this answer.95 percentile corresponds to a mark range of 120–180 (as per the trend was seen this year).Since marks were not officially given by NTA, I can't confirm the authenticity of the above data as it has been obtained from test-takers.You have just 4 months for the first attempt and I would highly recommend you to not take this attempt lightly. Begin your preparation right away and don't have any further delays or procrastination.Because, if you achieve your aim on the first attempt, you can concentrate on other exams as well as you can concentrate on JEE Main second attempt for a better score.I would be giving the list of chapters which are not very much tough and can be easily studied. Sometimes, direct formula based questions from the below-mentioned chapters is also asked.Physics:Units & DimensionsVectorsKinematicsWork, Power & EnergyCircular MotionLaws of MotionSimple Harmonic MotionThermodynamicsElectrostaticsCurrent ElectricityCapacitorsAlternating CurrentElectromagnetic InductionModern PhysicsChemistrySome basic concepts of ChemistryAtomic StructurePeriodic TableChemical BondingStates of MatterChemical ThermodynamicsChemical Equilibriump-block elementss-block elementsHydrogenGeneral Organic ChemistryEnvironmental ChemistrySolid StateSolutionsElectrochemistryChemical KineticsSurface ChemistryPolymersBiomoleculesChemistry in Everyday LifeAlkyl Halidesd & f-block elementsMathematicsSetsRelations & FunctionsTrigonometrySequences & SeriesDifferential CalculusApplications of DerivativesVectors3-D GeometryProbabilityQuadratic EquationsLinear InequalitiesStraight LinesStatisticsMathematical ReasoningInverse TrigonometryMatricesDeterminantsApplication of IntegralsDifferential EquationsAt this stage, you need to work smartly rather than hard work. You need to study the syllabus within 4 months. If you haven't enrolled yourself for coaching, I would recommend you not to take up.Don't solve every question and skip those questions, which are direct formula based or similar to the ones which you have already solved. In this way, you can solve some good questions.Currently, you need to allocate time equally for Class 11 and 12 syllabi. I would suggest you solve JEE questions in school as well and study for 12+ hours (not necessary) during holidays and stay away from social media, etc. for some months.Now, you need to make your fundamentals strong, so you need to solve NCERT textbooks for PCM of both grades. Once, done with that, you need to solve some reference books. I would recommend you to solve very few limited books as there is very less time.Start solving your coaching material (if enrolled) and begin by solving some illustrations and then solve some conceptual questions followed by Mains level questions.Give equal importance to all subjects, as a single subject could act as a game-changer in your result.To begin with, start solving the following books, once you are through with NCERT.PhysicsConcepts of Physics by HC Verma (Volume 1 and 2)Solve the last 41 years papersYour coaching material (if it's good)I would suggest that good coaching material might be useful for you. You can use them for theory as well as solving questions. You can purchase second-hand books if you don't want to purchase new ones.I won't suggest more books since you should be practically able to finish the above books.ChemistryInorganic Chemistry: NCERT (I found that many questions came from NCERT itself even in this year's JEE Advanced). Additionally, solve some question banks of inorganic chemistryLast 41 year's papersI would suggest that good coaching material might be useful for you. You can use them for theory as well as solving questions. You can purchase second-hand books if you don't want to purchase new ones.Mathematics1. Last 41 years of papers2. I would suggest that good coaching material might be useful for you. You can use them for theory as well as solving questions. You can purchase second-hand books if you don't want to purchase new ones.You need to make your concepts extra clear and must be ready with all formulas at your fingertips. That's why I would suggest you make a formula book for all three subjects.I found the following formula books quite useful:Physics: Handbook of Physics Buy Handbook of Physics Book Online at Low Prices in IndiaChemistry: Handbook of Chemistry Amazon.in: R P Singh: BooksMathematics: Handbook of Mathematics Buy Handbook of Mathematics Book Online at Low Prices in IndiaThe above-mentioned books are just some suggestions according to my judgement of your given situation at the moment. You can consult your teachers for books.Give mock tests every 10 days initially and later as many as you can depend upon your preparation. Analyse the mistakes being made during the exams and don't take any question lightly and a concept lightly, as anything could come. Try to practice as many questions as possible and never consider a chapter being finished and make proper and clean notes and revise notes frequently. Try to improve your accuracy and efficiency in solving questions as that is the most important thing to score high in JEE Main.I am again mentioning that please solve NCERT books for all the subjects as questions do come directly from the books. Don't leave any questions unsolved and in this way, your preparation for boards will be done quite easily.All the best…

Because Scientific Research & Development is never a priority for the Indonesian Government past and present. And these scientists never got exposed by our own media, and never been any campaign made to inspire young people to become inventors.To rectify this situation, the Government should open a dozen or more Research Institutes solely dedicated for research, and Incubators for inventors and tinkerers to advance new designs and new ideas for the future.
