Hi
I am a penultimate law student.
My doubts are two folds and the first one is:
1.I want to start preparing for CLAT PG from now on wards,but i have no idea from were to start,i don't know which books to buy.
2.Should i work for an year after my completion of my law degree?If yes,why?or is it a wise option to do llm.
can you please help me in this.
Thank you.

I can't help you with the CLAT prep but work experience will be valued by many LLM programs. A bit of work experience can often help if there is one or more 'poor' points on your CV - lower GPA for example.

LLM is basically an academic degree and for CLAT you need to study Constitutional Law, Jurisprudence, which are of 50 marks each and another 50 is for other subjects combined. Your books like MP Jain on Constitution will help you. Also refer to sample papers for better clarity.
