Hello

If you want to take admission in any university or college you may get admission on basis of your class 12th marks but it depends on specific colleges and course you want to pursue .

Some colleges or universities may require entrance exams to give admission and some can give you on basis of your 12th marks

So it's better to always check the special eligibility requirements or admission criteria of that college you want to get admission in .

If you will provide the course or college in which you want to take direct admission than I can tell you it allows direct admission or not.

HOPE THAT HELPS!
