It matters a lot and I feel that this phase is the most important one because you revise the whole content which you have read in the last 2 years.
I was a bit tensed but still kept on solving as many questions papers I can and noted down my mistakes in them to revise them later so as to avoid them in my actual exam.
I feel being self confident in the last few months is very important. If you feel scared or something, you can loose the momentum in your preparation and will lead to getting a lesser score.
I used to think that “I will definitely crack the exam and join my preferred college. I just need to give my 100% now without any fear which will make me sail through my exam joyfully”. You also need to be courageous and see the results. It will be very motivating and joyful which is required in the last few months.
ALL THE BEST FOR YOUR NEET!! JUST GIVE YOUR 100% NOW AND DON’T REGRET FOR IT LATER!!
