Study tips to achieve 250 in BITSAT 2025

Hey ya'll, i aspire to get into BITS RMIT 2+2, CS at Goa and Software engineering at RMIT. Last year's cutoff was 202 and this year it might increase. To be safe, i wanna aim for 250

Any tips? How hard is it to score 250?

If one were to start today, what should they focus on and what's the best way to prepare? Any free resources? Or courses? I came across mathango alot on this sub-reddit
