Most Important topics for NEET 2021 | Biology | Chemistry | physics

Your value doesn't decrease based on someone's inability to see your worth... Start where you are... Use what you have...  Do what you can...

Dream Big...  Work Hard.....

NEET entrance exam is the most prestigious and recognized national level exam at present for any young aspirant who wants to qualify NEET or & Other Exams. With the main ingredients being an intense dedication and properly channelized guidance, clearing this exam also requires a pinch of passion, positive attitude, and smart work.

But let’s face the truth. Biology, Chemistry & Physics being a broader term have many subjects and topics under it. Not to scare you, but it does have a HUGE syllabus.

It is indeed a tough nut to crack!

Worry not! Your very own study resource, ybstudy, lists out for you a simplified version of the syllabus, to help you understand the most important topics for NEET preparation.

What actually makes NEET exam so challenging is the dynamic nature of the question paper, where no questions are repeated, and hence it is also impossible to predict the topic and a corresponding number of questions in the next exam. Also, another difficult aspect of the exam is the requirement of in-depth knowledge of topics, testing the candidate’s real conceptual level in Part C questions, sometimes even with questions combining concepts from 2-3 different units. Hence, choosing which units to prepare becomes a daunting task.

Here is the list of important chapters for NEET UG with the percentage of questions asked in the NEET Exam from that topic. This can help the candidates to be a step ahead with the preparation.
