JEE MAIN 2020 PHYSICS PREPARATION
NATIONAL LEVEL ONLINE TEST
JEE Main April session is round the corner as the exam will be conducted from September 1 to 6, 2020 and its time candidates gear up their preparation. JEE Main Physics is an important component and requires regular practice and a good understanding of all principles and formulas relevant to it. Therefore, the first step to score high in this section is to grasp and memorize all of the relevant concepts and formulae as per JEE Main Physics Syllabus. That would help the students respond relatively smoothly to complex numerical problems.
Here is the chapter wise weightage for JEE Main Physics syllabus, based on the previous year trends.
No of Questions
Once you understand the topic-wise weightage and the number of questions that could be asked, you can develop a good approach towards preparation of important topics.
Mechanics is one of the topics with the highest weightage. It consists of 9 chapters. While preparing for this topic, consider the weightage of each chapter and dedicate an appropriate amount of time and effort.
Some of the important concepts in Mechanics for your preparation are -
Dimensional and error analysis
Acceleration due to gravity
Conservation of momentum & energy and collisions

One of the important topics for JEE Main and JEE Advanced this is a scoring section. Sub topics in this section to be covered up include radioactive substances, nuclear fusion and fission, dual nature of matter and x rays. Boards model should not be forgotten. The trick to ace this section include solving numerical problems.
NCERT is the best source to cover up basics. Then students can move onto HC Verma for covering up theory part and 3000 numerical problems by Schaum for practicing.
While preparaing and revisiong the physics syllabus candidates must take note of part B which states that 20 % weightage of the entire paper will be given to practical components that is experimental skills. As every mark counts it is advised to gain maximum from attempting this section the right way and gain maximum scores. The questions are quite simple based on the following topics:
|Vernier callipers: its use to measure the internal and external diameter and depth of a vessel.|
|Screw gauge: its use to determine thickness/diameter of thin sheet/wire.|

Candidates who attempt JEE Main wish to clear and make it to advanced level. Thus a comprehensive preparation for both the exams should be kept in mind. Several topics are covered under the domain of both the exams whereas certain topics are exclusive to each. Lets have a look in the difference of topics in chemistry section:
Topics in JEE Main and not in JEE Advanced
Topics in JEE Advanced and not in JEE Main

Joint Entrance Examination (JEE) is an admission examination to engineering colleges while the National Eligibility cum Entrance Test (NEET) is an admission examination to medical colleges. Both examinations are conducted by the National Testing Agency (NTA). JEE and NEET have a Physics segment with a few similarities and differences.
|Pattern||NEET Physics Pattern||JEE Main Physics Pattern|
Number of Questions
Type of Questions
Multiple Choice Questions (MCQs)
|20 Multiple Choice Questions (MCQs); 5 Numericals|
+ 4 for the correct answer, -1 for an incorrect answer
|+ 4 for the correct answer, -1 for an incorrect answer for MCQs; + 4 for the correct answer, 0 for an incorrect answer for Numericals|

It is important to note that the preparation strategies for NEET Physics and JEE Physics differ considerably. NEET Physics expectations are not as high as those of JEE Physics because it is an entrance exam to medical colleges while JEE is for engineering colleges.
1. While preparing for NEET Physics, one must not refer to books of JEE Physics because NEET does not require you to solve the complex numerical asked in JEE Advanced. This is also because NEET aspirants usually opt out of Mathematics after Class 10 while JEE aspirants have a strong relationship with Mathematics.
2. The exam pattern of NEET Physics and JEE Physics differs considerably. Therefore, preparation strategies must be formed accordingly.
3. NEET Physics asks only MCQs while JEE Physics asks MCQs and numerical. Practice should be done keeping this in mind.
4. NEET Physics preparation must be lighter than JEE Physics preparation due to the nature of the difficulty of questions. JEE Physics requires more intense practice with complex numerical.
NCERT Physics has all the important preparation topics to crack JEE Physics. Students require a lot of practice with NCERT books to ace the Physics section in JEE. NCERT Physics Solutions have been curated by subject matter experts after extensive research to provide the best study material for JEE Physics.

Edvizo has started conducting the sessions through the zoom app everyday from 6 a.m.to 9 p.m. Aspirants with doubts can get the solution through a live video
The group includes doctors, IITians and senior subject experts. The main motive of the group is to clear all the uncertainties of the aspirants in context to their preparation strategy and approach.
The announcement was made by Edvizo (a Guwahati based startup) which has launched the 30-days initiative to help the aspirants of JEE Main and NEET in resolving their issues/doubts online.
Over 50,000 students have been registered from all over the country and a tie-up has been made with around 2500 coaching institutes in order to carry the idea on a larger platform so that maximum students can get the benefit.
The main aim behind this initiative was to ensure that the students do not feel demotivated due to the lockdown and the flow must be carried. The team has also planned to start a career-guidance session online on the weekends for a duration of seven hours starting from 9 a.m.
