If I want to do 1 more mock, which one among dashcat 14 and 15 should I pick. Which one is most closest to cat. Can someone help me with this

As long as you don't worry about the test scores, anyone is fine.

Dashcats are not meant to motivate you by giving you inflated scores. Be smart and avoid them at the 11th hour.

DASHCAT 14

Thank you folks🙏

Instead of DASHCATs, the best choice is to attempt previous paper(if not attempted already). It boosts your confidence and calm down your nerves which helps you focus on you last minute revision. If see you an unusual question in DASHCAT, you might end up tensed trying to learn something new instead of focusing on the revision. If you are confident enough that you don't get effected by scores, you can attempt any of the DASHCATs just to plan your strategy for D-Day. Hope this works for you. All the Best!
