Hi

Yes, you can definitely join the autonomous college whose eligibility criteria you fulfill.

It is completely ok even if you don't fulfill the the eligibility criteria of the university to which that autonomous college is affiliated with.

This is because,

Autonomous colleges have the power of autonomy in the sense of conducting examinations on their own, can have their own eligibility criteria and can even change/modify the syllabus as per their need requirement.

Also,

Not all colleges become autonomous college, only quality colleges are selected by the University which are given the power of being autonomous so that they can improve the quality and standard of the college further.

So, you don't need to worry at all dear. If you fulfill the eligibility criteria of the autonomous college then without any second thought you can get admission in it

Best of luck for your future:)
