Right of the bat, you must have a bachelor’s degree if you want to be eligible to take the IAS exams, and that is just one of the eligibility criteria.

There are other criteria of eligibility for CSE as well that you definitely need to look into before applying for the IAS exam online.

So first and foremost, to be eligible to appear for the UPSC exam, you need to make sure that you meet the required educational qualifications.

The educational qualifications necessary to appear are not as steep as those required to appear for certain other exams like UGC NET and RBI Grade B.

By not steep I mean that the eligibility for UPSC does not require a minimum passing mark in your graduation certificate.
