Where are you all preparing DILR from? I have been giving cracku DILR sectionals, but they have same pattern of questions and quite different that from actual cat. Can someone recommend good sources?

what do you mean by same pattern of questions ?

Previous year questions are the best source to prep for LRDI, as maruti sir has mentioned many times.

MBA Pathshala - Questions from SIMCAT and PYQ Aptitude JAB - To increase your number knowledge and how to play with numbers. IMS Prayagraj - CAT Level Sets, Pranav Pant - BYJUS DILR Marathons. IIFT PYQ DILR sets(make sure you don't use a calculator for this) This is best for tough level DI SETS XAT PYQ(make sure you don't use a calculator for this too) CAT PYQ Combining all these we are roughly speaking more than 1000+ sets so I guess this is more than enough
