I have my call letter from NMIMS Mumbai and WATPI slot booked, what next? how do i prepare for WATPI?

Prepare in a way that aligns with ur Resume, Try to answer in a optimistic way, dont degrade yourself and voila

I scored 80% in cat 2022. I am in my final year of BCA. I will graduate this year. Should I go for a second attempt? I have no work ex and no internships. Am I behind? What should I do differently this year?

I will graduate around April. And sit for cat in Nov 2023. IIMs count work ex that exceeds 9 months so, it won't make 9 months. Do I still have a shot at IIMs without work ex?

Hi, you can take another attempt at CAT, and gain work-experience simultaneously. Coming to the CAT prep, see where your scoring well and where you need to improve. You can watch this video for how to plan well for CAT 2023: https://youtu.be/cZ10bUW64Bk
