Is there anyone who are not able to solve at least one set in mock? I'm the one person who is facing this, how can I overcome form this problem?

Cover all the basic types of puzzles through cracku dilr revision Playlist or elites grid revision Playlist and then try to solve questions on your own. Only see the solution if you can't crack it in 30 or 45 mins. You can develop a thinking pattern only if you try to solve questions on your own.

i guess out of the 7-8 mocks i have given their were 2 mocks where i was not able to solve even 1 set rest for every mock 1.5 sets is what i do consistently! solve variety of sets and don't take pressure of going through the sets for first 5-6 mins. choose 1 set and get through it after you have seen other 3 sets.
