Hello
As per your questions the eligibility criteria to apply for LLB course you should have a degree in any of the undergraduate course and you have already done that. Now what you need to know is which collehes are the best for that so I would suggest for this most of the good universities are already done with there CET exam like delhi university, symbiosis, jamia etc. I would expect that you don't wanna waste your year and wait so you can give exam.for bharti vidyapeeth university because they are yet to conduct there exam for this year so you can try for that.
I hope this helps you and if you have any more questions please drop a comment below.
Best of luck.
