in my provisional degree certificate they told year of passing july but in marksheet august there is any problem during Applying for college
No, this won’t create any major problem. Colleges and universities generally consider the final marksheet and the fact that you have cleared the degree, not the exact month. Minor differences like July in provisional degree and August in marksheet happen because results are declared in one month but certificates are issued in another.
If the college asks, you can explain it’s due to the university’s result declaration process. It won’t affect your admission.
A small difference like year of passing being mentioned as July in your provisional degree certificate and August in your marksheet usually does not create any problem while applying for colleges. Both documents are valid since they are issued by your university. Colleges generally consider the month or year of result declaration, not the exact date.
