LLB

Hi,
You have a pretty decent ranking. Considering other factors like your 12th scores, you must be able to get through. But it's always good to give it a try and have a good back up plan. Good luck, hope this helps!

After doing B.Com, LLB is only for 3-years only.

Fashion Designing and LLB are two complete different courses having no relationship in between. I would personally recommend you to concentrate in one instead of both. At the end of the day, either you can make your career being a lawyer or a designer. You can be both but you won't be able to give your 100% completely in one. So make a wise decision.

I think UPES, Dehradun is better than SRM University, Delhi in all aspects. SRM University is just looting student's money. There is no secure placement in SRM.

The 5 year LLB course will have a Bachelor's degree as BA LLB, BBA LLB and likewise. It will save your 1 year and will provide more opportunities in understanding Law than the 3 year course. For 3 year course you have to do your graduation first. And in 5 year course you will be doing both Law and graduation together. Yes you can give CLAT after graduation but CLAT is for BA LLB course, which is of 5 years and not 3 years. So, if you want to appear for CLAT, you will be doing BA.LLB for 5 years.

Yes, it does provide 5-year BA LLB course.

Your rank is quite decent, so be hopeful. Keep an eye on the vacancies. Please check out on the link:

Your class 12th marks have least impact on your placements. All that would matter is your CV, grades and work ethics.
