Hi dear aspirant!
You can easily pursue BBA LLB even you had scored 70% in class 12th and 10th. You can easily get good marks if you learn the subjects with full dedication because you've secured less in class 12th so improve your marks in graduation. Try to take admission based on competition results. If you want to admission to Law then you need to appear for CLAT and Various central university exams. Some private institution also conducts their entrance exams.
If you are someone who is inclined towards the law then definitely you should pursue law. See, marks never matter if you dare to change the thinking of others. Just be focused on your goal.
