One of my friends recently got admission in AFMC Pune and surprisingly enough she claims that she never prepared for her college purposely. In fact, it was only after clearing the cutoff for screening that she decided to actually consider getting admission. The only trick that helped her was that she focused only on preparing for NEET initially and did not worry about the screening. The trust is, that the screening process is rather unpredictable and not much can be prepared in a short span of time. So it’s better to invest your efforts and energy in something that is completely in your control. Once you clear NEET, you can start preparing for screening also.
Hope this helps you!
