Awesome progress! After Ravi Prakash sir’s sets, I jumped to CATKing Mock Tests and IMS SimCAT and Sectional Tests, their DILR questions are very CAT-relevant. Also, TIME material’s handouts and DILR booklets have some gem-level sets (especially the advanced ones), though the format is a bit dry. But if you want to replicate CAT DILR's unpredictability, that’s the route. 

Hey, great going! You can now move to practice sets from 2IIM’s free LRDI archives. They are categorized by difficulty and type (arrangement, games, matrix, etc.), which helped me cover my weak areas strategically. Once you’re done with that, you should definitely explore Arun Sharma Level 3 sets, they are tough but good mental gymnastics for LRDI fluency.

I’m in the same boat, I finished around 130 sets from Unacademy’s Ravi Prakash sessions. For variety and difficulty spike, I shifted to CAT 2017–2023 actual LRDI sets. CATKing also has a lot of problems to solve. Trust me, nothing beats actual CAT logic puzzles for pattern and time-pressure practice. I’ve also subscribed to Puzzles from PrepZone Telegram group, really underrated source for handpicked tough sets.

That’s a solid base if you're doing 125–150 sets from Ravi Prakash Sir’s lectures, I did something similar last year. After that, I highly recommend the CATKing Real Mock tests and Cracku LRDI Daily Target sets. They are time-bound, updated with recent CAT patterns, and come with solutions + detailed video explanations. Also, their difficulty gradually increases, which helps maintain consistency and stretch your limits.
