Guidance for TIFR GS physics preparation

I'm planning to prepare for the TIFR GS Physics entrance exam and would really appreciate advice from people who have successfully cleared it or are currently studying at TIFR.

​

I am currently in 3rd SEM building my foundation in Physics and Mathematics and want to prepare seriously for TIFR GS. Any detailed advice, book recommendations, study plans, or personal experiences would be extremely helpful.
