Please suggest me which mock test series should i buy??

go for IMS without any second thought its nearest to CAT lvl and has around 12000 test takers for every mock....although its quite expensive ..but i have a extra IMS mock material..mmy friend purchased it and then dropped cat LOL...so i can hand it over to you if you need..at a good price ..let me know ,

You can go for Cracku or IMS SimCAT. Both are good options for CAT mock practice. Try a free mock first and see which suits you better.

catking mocks for 999 or CL 5 mocks for 999 which is better??
