Hello Neha. Preparing for NEET in 4 months is not easy at all and will require a lot of dedication and hardwork but its not impossible either. Its better to focus mostly on PYQS and see what are the patterns of questions asked in previous years. Prepare from one shot vedios and focus mostly on very important lessons only. Dont waste your time on low weightage chapters and focus mainly on chapters which will give you higher marks. But it does not mean that you should skip chapters. Study as much as you can but on the basis of weightage priority. For physics and physical chemistry you don't need full detailed lectures just a simple clarity of the topic and formula memorisation is all you need. But that does not mean to skip topics and learn half heartedly. Prepare well but its better to do smart work at this point. Do not solve unnecessary questions from any chapter as it will waste your time. Only questions to be practiced at this time are PYQS. Read one chapter from biology each day as biology contains 360 marks in NEET. In the same way prepare inorganic also by reading NCERT or seeing one shot vedios. For organic chemistry also watch one shot vedios but do practice organic the most because according to trends in the previous years organic has had the mostly weightage. Do read NCERT for organic only if you have time left other wise its better to focus on the lectures.

I hope i was able to help you. THANK YOU!
