Hey

I was stuck in same situation as you are right now just keep a thing in mind if you're straining your brain you just can't get along with physics be flexible stay on your concepts don't let your basics ruin after doing so much of questions competitive exams like NEET only test out basics and basic knowledge until unless you are on concepts you'll get through everything including physics just keep calm go through previous years papers and also take test series provided by allen akash n other institutes....good luck hope you get succeeded in your endeavours. 

Hello buddy, just don't be tensed, keep your cool, and stick to the basics. Keep revising the concepts, keep brushing your concepts , stick to NCERT and if possible give as many mock tests as possible. I hope you do well in your exams. All the best for your future endeavours.  Thank you for using Carrers360.
