10th in 1978 in vidharb maharashtra

Hi Brunda,

Thanks for asking, the answer to your question is, No. You are not eligible for LLB as class 12th passing marks are the basic qualifications for LLB according to the Bar Council of India.

For seeking admission into 3 year law course qualifications needed are only 12th   and three year graduation, with 12th, is the basic qualification for seeking admission into 3 year law course, while for seeking admission into 5 year law course  only 10th and 12thqualification suffices with 10th being the basic qualification for seeking admission into the 5 year law course.

Bachelor's Preparatory Programme (BPP) of IGNOU is a six-month preparatory programme offered for those students who wish to pursue higher education (graduation and post-graduation) but have completed schooling only till class 10th and haven't done class 12th. 
Hope it answers you.

Good Luck!
