Query about my name

Respected Lawyer, i have a question related to my name, actually in my all documents including aadhar card, pan card, my name is 'Abhi Sinha' also in my 10th marksheet my name is 'Abhi Sinha' ( i have passed my 10 standard from cbse school from bihar), but in my 12th Certificate my name is 'Sinha Abhi Rakeshkumar' as i have passed 12th standard from Maharashtra board school (Rakesh Kumar is written without gap) and the respective teachers said it's compulsory to add father's name in your name here in Maharashtra (My father's name is Rakesh Kumar Sinha) , and now that i have taken admission in Dy Patil College, Pimpri Pune (I'm first year student) they have asked me for the name which i want to get in graduation passing certificate, so can you please let me know which name shall i give to them? 'Abhi Sinha' or 'Sinha Abhi Rakeshkumar'. Kindly note that in all the other documents my name is 'Abhi Sinha' except 12th marksheet, as the teacher and principal said it's compulsory to add Father's Name in middle of your name. So if their will be need to change the name in 12th marksheet, kindly let me know what should i do, should i get an affidavit or gazette or i should go to the main branch of Maharashtra Board pune and ask them to change the name on the marksheet. Thanks in Advance
