Thanks for A2A. Just to give you context, I was a part of the CATKing GD-PI course this year. I have converted the NMIMS core program. So assuming I'm the right person to comment, find below the reasons for you to sign-up for CATKing. They conduct online live classes every day on GDPI prep, WAT, and the basics of marketing and finance. In case you miss them you can watch the recordings anytime. Huge collection of interview experiences sorted based on college.
