Detailed Paper Analysis of NEET 2019

Let us see a detailed NEET Paper analysis. Hence, the aspirants can understand what to expect in NEET 2020.


The physics section is considered as the toughest section out of the three subjects. NEET 2019’s paper was moderately difficult. The students had to answer a lot of calculation-based questions. Compared to NEET 2018, it was slightly tougher and lengthier.

The weightage of questions in Physics was just slightly imbalanced. For instance, 24 and 21 questions were coming from class 11th and class 12th respectively. The following table represents the number of Physics questions, which were asked mostly to the aspirants.

Name of the chapters Number of questions
Mechanics 19
Thermodynamics and Kinetic Theory 5
Electrodynamics 9
Optics and Wave Optics 5

Strategy for the exam

Have focus

First, if you are preparing for NEET, you should take mental preparation for it. Examination preparation is quite difficult. You need to maintain a positive approach towards your goal. With the recent high levels of competition, students get easily disheartened and start doubting themselves.

It is important to just focus on your preparation and to believe in yourself. Due to the intensity of the preparation, it is very important to be ready to put in all the mental and physical effort. Hence, the students can clear the exam.

Stay on the syllabus

You should know all the topics in the syllabus for the exam. For this, you should check the syllabus at regular intervals, and then collect the study material for preparation. This will also ensure that you do not deviate from the topic at hand and study irrelevant material. Reference to best NEET preparation books and previous years question papers for NEET will go a long way into your preparations.

Time Management

Following a strict timetable as per specific syllabus and targets is very important if you want to complete the syllabus on time and also leave an ample amount of time for revision. Making notes of topics while preparing them would cut a lot of time during. You would thus solve more and more problems to discover more and more new tricks. Try to give more time to NEET important chapters and topics that you feel are your weak points. This will help you to perform well in the exam

Study with a group

Working with a competitive study group helps you successfully prepare for NEET. Group discussion creates a cooperative environment, helping you to multiply your knowledge exponentially, while also being a great way to have social interaction. Students can Quiz and challenge each other with questions from the NEET syllabus.

It should also be pointed out that study groups should be made with people who want to study. Make sure none of the people invited are a cause for distractions. Often one amongst the group will bring up irrelevant topics and cause everyone else to lose focus in their studies.

Take Mock Tests

One great way to assess your skills and knowledge is through mock test. You should start taking the mock test after you have completed all the topics and subjects. Ideally, taking a mock test a month before the exam makes more sense. That is because taking a mock test is there for practice and not for studying. Students can start taking the mock test before one month of the exam and two in a week will be a good number.

Previous year question papers

One of the most important tips and things to do when preparing for NEET exam is to solve previous year question papers. It helps students to understand the exam pattern. In addition, the aspirants can identify the type of questions asked, syllabus and of course the complexity level of the questions being asked in the NEET exam.

On the other hand, solving previous year question papers leads to enhanced speed, accuracy levels of the students. Consequently, they can implement a strategy to attempt the question paper. This can help them attempt a full question paper when taking the actual exam.

Revision after studies

Covering new topics without revising the already covered ones will be a waste of time. Without consistent revision, the students forget the concepts they covered in the past. Moreover, the students will spend more time learning chapters or topics. NEET 2020 revision will also help you in increasing your test-taking speed and overcoming panic. It will also give you a clear picture of the topics you’re weak in. For better understanding read NEET Revision Plan.

Avoid beginning new topics near the exam date

If you are following this article, you know you should have a schedule for time management. Make sure to complete all your study topics a few weeks before the NEET. Please ensure that you keep the last two weeks only for the revision and for taking mock tests. Beginning new topics a few days before the examination wouldn’t help you. Instead, you will start to panic.

Avoid distractive elements

Distractions are to be avoided during NEET preparation days, especially when the exam is near. Therefore, spend less time on social media interactions like Facebook, WhatsApp etc. However, recently many social media groups have started offering some important exam tips. If you do plan on spending time on social media, you can check out such groups too.

Pay attention to your health

Don’t over push for studies, ensure you take rest and exercise regularly. Too many sleepless nights and improper food will take a toll on your health. Having a good diet is as essential as studying. Your brain needs regular energy and rest to work and function efficiently. You must ensure that you get at least 8 hours of sleep every day. Apart from that, you also need to ensure a proper balanced diet. As the saying goes, “A healthy mind resides in a healthy body.”

It is only with practice that you gain confidence over topics that are asked in NEET. Practice can be done through Sticking to the syllabus and practicing NCERT books is the pro-tip to get a high score in NEET 2020.

Hopefully, this article helped you with your queries about NEET 2020 exam, and how to prepare for it. Keep these strategies in mind while studying, and also keep the syllabus for the NEET exam close by.

All the best!
