This course (M.Sc in nanotechnology/research) is comparatively new at AUH as well, that can be one of the reasons that you haven't heard much about this college. But this course promises immense job opportunities after doing this course.

5 years integrated law courses can be taken only after completing 10+2. You may complete your 10+2 and after that appear for the law entrance exam and meanwhile, in 10+2 you may appear for the entrance exam side by side.

There is no mandatory subject in HSC for pursuing law. You may opt for any stream whether science, commerce, arts or other and appear for law entrance. However, if you have realized that you have to pursue as a career, you may take commerce or arts in 10+2. Commerce will help you in creating a base for subjects like taxation, companies act and others. Whereas, in humanities, you will be benefited from subjects like history, civics and political science which will give you a base for the constitution and other related subjects.

Hi Pradha,
It is very difficult to predict the cut-off now. Once the results will be out all the college's will release their category wise cut-off list. You will have to wait until then.

Hi Aishwarya,
The national law colleges except for NLU-Delhi take admission through CLAT. Other colleges conduct their own exams like BHU conducts BLAT and Symbiosis conducts SLAT.
