Hi Team, I am able to solve 2 sets of arrangement/circular arrangement or puzzles accurately in 40 mins but to be on safer side which of type of set should I practice more in this less time to become confident in solving 2 types of sets in actual exam.

Hi Sets from Arrangements have appeared a lot of times in CAT, every year if not a direct arrangement based set but a set where concept of arrangement is required has appeared in CAT so it is good you are done with that , try to work on venn diagrams a bit as venn based sets have also appeared a lot of times in CAT. Try to work a bit on DI as well as a DI set if it comes you can approach the same . As time left is less, focus more only on these . Also watch this video : https://youtu.be/bwZ0a5oFrG8
