How do I improve grand test scores while preparing for the NEET PG?

See improving GTs scores in NEETPG has three components-

1. improving content, more subjects you cover in classes, more class notes you are thorough with, you tend to improve your GT score
2. Analysis after every GT about which subjects are your weakest.
3. Listen to video solutions (DAMS GTs come with video solutions) and understand teacher perspective of that test
4. Plot a graph of number of right you are doing with a target of consistently getting 200+ correct.

Wish you best of luck.
