can anyone share me the srategy for dilr? I m unable to do 2 complete sets. In every mock I ended of doing 1 or 1&1/2 sets with 95-100% accuracy.

you must make an approach book for LRDI. List out all the LRDI sets that you have solved to date and jot down the approaches you followed to solve them. This can be done in less than a day. Then you just have to revise this book till CAT.

There are 2 approaches to solve DILR section. 1. Identify 2 of the 4 simplest DILR that you are confident in solving and solve them completely with 90+% accuracy. 2. Solve starting from the simplest DILR, but not necessarily completely, after tackling the puzzle for 5-10 minutes, try to see if you can answer 2-3 questions based on what you solved. Move through 3 or all puzzles like this and come back to the simplest one if you feel like you have time to solve it completely.

i have given free mock of cracku. i wanted to know whether difficulty level of that mock was same as real cat paper

in CAt you will get 8-9 questions of easy level and 5-6 of moderate level. don't try to learn anything new in these days. practice on your strengths and you are good to go.
