PCB student switching to JEE maths in drop year is it realistic?

I’m a PCB student currently preparing for NEET

My biology is strong, chemistry is average, but both my physics and maths are weak. I haven’t studied maths after 10th, so I’m basically starting from zero.

The reason I’m considering a drop year is because I’m interested in IAT and research-oriented fields, not just the typical medicine path. I also feel that learning maths will open up more career options for me in the future.

I’m thinking about taking a drop year and preparing maths to a decent JEE/IAT level.

Is this realistically possible in 1 year if I start from scratch?

Also, what should be my starting point and what resources/strategy would you recommend?

I would really appreciate honest advice, especially from droppers or people who improved from a weak level. Please be honest, even if it’s harsh.
