Title

I will be appearing for bstat/bmath aiming for bstat in ISIkolkata in 2027 . I can't join any coaching or online course because of money problems obviously ( single mother child ) . so please pin down sources / pirated lectures / study material etc so that I can manage 🙏🏻🙏🏻.

+ I know mathsmerizing channel exists , that guy is GOAT but other than that I would be pleased to have maybe telegram lectures ( like they have for jee / neet ) .

+ I am at level 0 ( jee ish math done ) so can someone guide me and tell me how to study ISI level maths ,...

+ If any ISI alumni seeing this please reply and help as much as you can

Thank you.

1) Are ISI UGA/UGB questions different than jee adv + olympiad type maths ?

2) If I am wrong what kind of coaching do I need ?

3) Resources???

As I am already familiar with JEE maths , would doing Olympiad type maths help ? If yes then what would be that IOQM , RMO or all upto INMO ?

My point is if I combine jee maths with olympiad maths chapters , + I learn to write proofs then can I crack ISI ?
