Most Probable Topics to Crack the JEE Main 2020 Exam

JEE Main 2020 is not just a popular engineering entrance exam, it is the only way to get admission in the prestigious IIT’s, and we are sure you must have dreamed about getting admission in one of the IIT’s and want to build a dream upon it. JEE Main is also the eligibility test for JEE Advanced which offers admission to IITs & ISM.

The JEE, as we all know, is conducted by CBSE for admission to B.E./B.Tech & B.Arch. Courses and is considered one of the toughest competitive exams for engineering in India!

Well just to open your eye to the competition, around 15-16 lakh engineering aspirants appear for the JEE Main, Yes! It is a big number, but it won’t matter if you are prepared well, for this should devise a self-strategy to compete in the race!

Besides devising ways on how to crack JEE Main, it is imperative to know the important topics for JEE Main, and this is what you will be found in this blog.

JEE MAIN 2018 Important topics

From the year 2019, new changes have been introduced by CBSE such as making it mandatory for the applicants to have Aadhaar card issued by UIDAI for filling the application form and a report suggests that the paper of JEE Advanced 2020 may include short-answer type questions too.

Let’s understand how much cut off is expected to enter into the second stage, which is your primary goal at this time.

Category Expected Cut-off Marks of JEE Main 2020
General 88
Scheduled Caste 38
Scheduled Tribe 33
Person With Disability 5


JEE Main exam pattern is generally based on three subjects Physics, Chemistry & Mathematics.

Well, that is all you have been studying.

You must follow the JEE Main 2020 Syllabus in order to prepare the topics that are must and highly important as well as scoring. JEE Main-2020 will be conducted as a CBT (Computer Based Test).

With each passing year, JEE is becoming more and more unpredictable, and the issue to address here is that the students have a preconceived notion and mindset on how they are going to attempt the paper!!

Taking last year JEE as an example, the questions asked in the examination were not tough but lengthy and time-consuming. Physics, in particular, saved many who ignored NCERT; questions from Semiconductors were extremely basic; Chemistry especially was completely from the NCERT.

The analysis is always different from that of the previous year paper, and again the same will hold for JEE 2020. Thus, the difficulty level is going to have some variation. The overall difficulty of the paper is bound to remain the same. So the order of attempting the paper should be subject to the difficulty in the actual exam.

We suggest you to avoid attending the exam with a pre-conceived mindset. Believe us! Confidence and mindset make all the difference in exams like JEE Main.

Let’s get to the main stuff! – THE IMPORTANT TOPICS (SUBJECTWISE)

Important topics for Physics in JEE Main 2020

The physics portion for JEE has 20 chapters, all in all, that has to be covered over 2 years’ time. They are Dimensional Analysis – Although a very easy chapter but knowing correct units and dimensions for physical quantities can easily help you eliminate options in multiple-choice type of questions, Gravitation & Electrostatics, Current Electricity & Heat Transfer – again these are conceptually similar to each other, Electromagnetic Induction, Waves & Sound, Geometrical Optics, Thermodynamics, Kinetic Theory of Gases, Rotational Dynamics.

Question Pattern followed in Physics

  • Current Electricity: 8 questions asked in the actual JEE paper each year on an average
  • Electrostatics: 4 questions
  • Optics: 3 questions
  • Heat and Thermodynamics: 2 questions
  • Law of Motion: 2 questions
  • Waves: 2 questions
  • Simple Harmonic Motion: 2 questions

Tips for scoring well in Physics

Note down the formulae and results; it will help during revision. Practice as many questions as you can, keeping in mind the availability of time. Avoid lengthy and complicated problems at the last minute, if time is limited!

Focus on your strong areas.

Important topics for Chemistry in JEE Main 2020

Chemical bonding & the periodic table – This is by far the most fundamental and the most important topic in Chemistry. If you can master Chemical Bonding and the properties of periodic table elements, then Chemistry will be an easy subject for you over many years to come.

Other topics include Carbonyl Compounds & their derivatives, Redox reactions, Mole Concept & the concept of equivalents, Solid-state, solutions & gases theory, Thermochemistry & the Second Law of Thermodynamics (Remember, we told you about this in the Physics section).

Question Pattern followed in Chemistry

  • Transition Element and Coordination Chemistry – 3 questions
  • Periodic Table and Representative Elements – 3 questions
  • Gaseous State – 2 questions
  • Atomic structure – 2 questions
  • Amines – 2 questions
  • Solution and Colligative Properties – 2 questions
  • General Organic Chemistry – 2 questions
  • Carboxylic Acids and Derivatives – 1 question
  • Hydrocarbons – 1 question
  • Carbohydrate, Amino Acids, and Polymer – 1 question

Tips for scoring well in Chemistry

Chemistry is amongst the tough subjects as it involves cramming of formulae and reactions. Thus, understand the conceptual base of the topics. Also, remember! The Periodic table is the most scoring part.

Final Tips (Must follow to prepare efficiently)

Make a proper study time-table and follow JEE Main 2020 syllabus very carefully.

To score well in the examination, students are advised to prepare PCM subjects taught in 11th and 12th grade thoroughly. Candidates can also go through the past years question papers to know about the difficulty level of the exam. 

Practice mock tests to know your weak areas. Time Management is essential. Set and stick to a timetable so that you can easily decide and divide study hours. Divide your time well among school, tuition, coaching classes, exercise, entertainment, etc.

Finally, don’t take life too seriously; do not take the stress and keep yourself healthy. You must create violent plans and execute with much will; this would lead to success not just here, but in LIFE!!
