Bro, prepare for these exams together.  I made the same mistake last year, I just focused on cat 24, eventually screwing up DILR and then was not completely ready when NMAT. So this year am going all guns on all these exams. 

Hey,

Totally get what you’re feeling—been there myself! If QA is your weak area, I’d suggest you start your prep for NMAT and SNAP alongside CAT. The concepts are mostly the same, so there’s no need to wait until after CAT to begin.

For NMAT, focus on speed: quick calculations, timed quizzes, and use the NMAT Official Guide (great for practice).
For SNAP, practice mixed-topic sets, simple arithmetic, and build speed + accuracy—it’s 60 Qs in 60 mins with negative marking.

Best of luck!
