Dear Xyz,

Nothing is impossible. If you are determined enough to crack AIIMS then you can certainly do it. Make a schedule and work on it every single day. Always start with NCERT books, they are the holy books for any medical exam and then move to other help books. As here we are talking about AIIMS then do read newspaper and books of general knowledge because question comes from it. Practice as much as mock test papers. Everyday solve questions within a time frame, this will help you in exams. Make formula charts and paste them on your study table.

Regards
