12 lakh students sat for JEE Main 2017 while there were only about 11,000 B.Tech seats in IITs. Since all the engineering students dream of joining IITs, we saw about 110 students competing for each IIT seat that was available. Isn’t that daunting? But you realise that only at the last minute. No one really talks about it when you are in Class XI or in Class IX – when you just start your IIT JEE coaching.
What no one tells you is that IITs not a place for bright students. Over the years, many of the brightest students of their respective classes have failed to make it to the IITs while students who have been considered ‘quite average in studies’ made it to the most coveted IIT seats. The different between ‘success’ and ‘failure’ in IIT JEE preparation simply depends on your time management skills, your preparation strategy, your study plan – and above all, your commitment to crack the exam.
Here are some of the time-tested tips that have delivered results for several engineering exam toppers and that can help you zoom up your IIT JEE preparation 2018:
Too Many Books are Not Good for JEE Preparation
You cannot hope to master any concept – be it Physics, Math or Chemistry – until you understand its basics or fundamentals well. If you are weak in concepts, do not attempt solving practice questions IIT JEE coaching providers hand out to you straightaway. This may only put a dent in your confidence. First, read the chapter once again and try to understand it.
NCERT books are great for starters – as they are easy and to-the-point. Use reference books recommended to you for IIT JEE preparation 2018 only when you need help on a particular topic. Do not put too many books on your table as the course may seem insurmountable to you.
In Physics, you should first do practice papers and course modules provided by IIT JEE coaching of your choice, then, go through solved examples of H C Verma’s book and then, do the exercise given in the book at the end of the chapter. Short answer-type questions will also help you learn your theory better. In the later stages, you can start trying to solve questions from Irodov’s book as they are easy and conceptual.
Similarly, you should start with NCERT book and coaching modules for Math and then, move on to S L Looney examples and exercises. In Chemistry, O P Tandon’s books are good for practicing problems.
Important Topics for IIT JEE preparation 2018
JEE syllabus is humongous and there is no doubt about it. When you have less time, you have to study smart. It means that you need to concentrate more on topics from which carry more weightage (or from which more questions are asked in JEE exam). Here is a disclaimer though. All topics are important and must be studied well. JEE exams are difficult to predict and you may find 10% marks stemming from a single chapter that you skipped. That said, here are the topics we thing you should focus on more:
Out of 20 chapters in Physics that you study in Class XI and XII, the ten more important ones are:
- Dimensional Analysis: This is an easy one. Knowing units and dimensions of various physical quantities can prove invaluable to you when you need to eliminate options in MCQs you are not sure about.
- Gravitation & Electrostatics: These chapters have similar concepts that become easier to pick up when they are read one after the other.
- Current, Electricity & Heat Transfer: Again, these chapters have similar concepts and should be read one after the other for quicker understanding. Do note that sometimes similarities can be misleading and you need to pay special attention to these points.
- Electromagnetic Induction & Waves & Sound should be studied together.
- Geometrical Optics & Thermodynamics should be read together.
- Kinetic Theory of Gases & Rotational Dynamics go together too.
9 most important topics in Physics (weightage-wise) are:
- Magnetism – Weightage: 6%
- Heat & Thermodynamics – Weightage: 6% (important both for Physics and Chemistry)
- Centre of Mass, Momentum and Collision – Weightage: 5%
- Simple Harmonic Motion – Weightage: 5%
- Wave Motion and String Waves – Weightage: 5%
- Nuclear Physics – Weightage: 5%
- Modern Physics – Weightage: 5%
- Rotational Dynamics – Weightage: 4%
- Fluid Mechanics – Weightage: 2 – 5%. (Some of the trickiest JEE questions are based on Bernoulli’s principle).
You can expect 2 to 3 questions from each of these topics in your JEE exam.
When it comes to engineering, you have to be sound in Math. You need a lot of practice to master Maths too. Truth be told, you should not skip anything in Math. Still, 7 most-important Math topics (weightage-wise) from which 2-3 questions are asked in JEE exam every year are:
- Integration – Weightage: 8% (covers both Definite and Indefinite integration)
- Probability and Statistics – Weightage: 7%
- 3D Geometry – Weightage: 5%. These questions are generally straightforward types.
- Vector Algebra – Weightage: 5%
- Complex Numbers – Weightage: 5%
- Parabola – Weightage: 3%
- Trigonometric Ratios – Weightage: 3%
Out of 25 chapters in Chemistry, you should pay special attention to the following during JEE preparation for 2018:
- Chemical Bonding & The Periodic Table: Must-do. If you can master this one, you will love Chemistry forever.
- Carbonyl Compounds & their derivatives
- Redox reactions, Mole Concept & the Concept of Equivalents
- Solid State, Solutions & Gases theory
- Thermochemistry & the Second Law of Thermodynamics
6 most important Chemistry topics (weightage-wise) are:
- General Organic Chemistry – Weightage: 7%
- Atomic Structure – Weightage: 5%
- Aldehydes and Ketones – Weightage: 5%
- d & f Block Elements – Weightage: 5%
- Gaseous State – Weightage: 3%
- Hydrocarbons – Weightage: 2%
Visualisation is the Key to Understanding PCM Concepts better
Try to draw a diagram for everything first and then, try to answer the question. Practice is the only key to develop your problem-solving skills.
Mind maps are a great way to learn major concepts, facts and formulaes of a chapter. When you are stuck with a topic, google for its mnemonics, video tutorials, and mind maps. It should help you understand the topic better.
Other Things to Remember:
For analytical questions, read through solved examples first and then, try to solve similar questions.
Keep the last 3-4 months for revision and practicing mock tests and previous years’ question papers.
