MATH ?????

im very average at math. i do understand the concepts but my speed is not good, something thats essential for mcq based tests. also i struggle at integration quite a bit. do u think i can improve my speed and understanding enough to get a decent score in just a month or so thats left for cuet? (aiming for bms)

also pls tell me abt the difficulty level like can i get a good score if i do just ncert????
