Its a very challenging task. But best wishes

Hi Aiswarya! According to me, it will be very difficult to prepare for AIIMS in so much less days. But still there is always a hope and you can always try. Here are few tips:-
1) Practice A/R questions as they play an important role.
2) See and solve the question papers of past 10 years at least and get to know the pattern.
3) For Biology, read NCERT and solve A/R.
4) For Chemistry, read NCERT or your notes to sum up fastly.
5) For Physics, go for questions than theory. Go through important points from NCERT.
6) For G.K., watch a bit news and current affairs and don't give much time on this section.
Thank you!
