Educational Certificate Attestation

What is the educational certificate attestation process

My answer is valid for Indian nationals (specifically residents of Mumbai and students of Mumbai University). I have recently completed the attestation process for both, graduation and my marriage certificate but since this question is only about education certificate, I will only mention the steps required here. Please understand that you may have to visit several places in order to ensure that you have received all the mandatory stamps, so if you are lack of time then this might not be the best option for you.
