Hello Rujuta, see if you really want to repeat and determined for that, then why not try for JEE instead of just CET. If you prepare for JEE very properly, you can very easily score 160+ in CET without even knowing the syllabus. And once you've prepared for JEE, you can give all exams like JEE, CET, COMEDK, BITSAT etc and have very wide number of options next year. But repeat only if you are very sure about yourself of working hard, otherwise go for private institutes this year only.
