You can definitely do LLb Cojrse from Private colleges with good reputation and rankings as per Indian Bar Council.

However any correspondence degree in Law is not recommended as it doesnt jave practice and practical expertise required in Courts.

Hi,
If you want to practice as an advocate then go for Regular LLB programme from recognized institute. As long as you are doing a regular LLB programme from a BCI recognized college/institute there is no issue. But if you want to become an advocate after doing LLB from Distance/private/Correspondence mode then there is a big issue, BCI doesn't approve such programmes and as a result you won't be able to practice law as an Advocate. I hope it helps!
