Delhi University (DU)

Amity law school Delhi is better option according to my view . but choice is yours.

Dear Atul Verma,
Let me explain about the entrance test. Any entrance test that consist of Arithmetic, English, Logical reasoning and general knowledge on contemporary issues. Mathematics and English that will be 10th class standard in most of the situation. If you are week in mathematics related areas you can join some training institutes like TIME, IMS etc. or you can also start preparation with RS Agarwal for aptitude and for English Wren and Martin. And regularly read English newspapers. Previous papers need to be practiced. All the best.

Hard to say, UK is tough now because of the work permit issues around international students. And with the recent exit from EU, things are going to be more tough we assume. USA on the other hand is a different league and very competitive. Try Australia, Canada, New Zealand - these countries have great post study work permit options for international students. Remember that a job is no guarantee unless you are qualified enough and have the proper skills.
Best Wishes

You should refer the prospectus of colleges. Every college has different fee criteria.
