Hey

You have scored very less marks in your Graduation Because most of colleges & Universities ask for at least 50% marks in graduation (45%for reserved category), 

So, please check the official websites of some colleges and check the eligibility criteria and if you find yourself eligible then you can apply for that colleges.

But there is one more way if you want to be a lawyer, ifiyou are interested, take admission after intermediate in 5 year LLB course through CLAT.

Hope this answer may help you 

All the best :)
