I am Purushotham from India. I am struggling with one issue. Could anyone pls clarify me.

In my all educational certificates I have my name as "Purushotham Ramakrishna Pacholla"(Firstname Middlename surname), but in my passport and GRE I have only "Purushotham Pacholla"(Firstname surname).

Could anyone tell me it will become a problem during admissions or not? or Do I need to change the name in passport and write GRE again?
