Hi there.

For Unreserved category, 450 marks are too less to get into a government medical college. Please aim for more than at least 510 in order to have chances of getting a seat.

To be very honest, now I'd suggest you to only focus on your studies and not think about marks. Just complete your syllabus as soon as possible. Write Mock tests, solve previous year questions and keep moving forward. Remember, every little victory counts. Try to score more than 300 in Biology. NCERT of biology and Previous years questions are enough for scoring 300+ in biology.
