There is a good chance you can get admission into the first year of a Diploma in Computer Management (CM) or Information Technology (IT) branch with 75% in your 10th standard.

Generally, the basic eligibility for diploma programs is passing 10th standard with a minimum percentage (often 50%). Some institutes might require a higher percentage, but 75% puts you in a good position.

Diploma programs in CM and IT are popular choices, and many institutes offer them. This increases your options for finding a program that accepts your score.

I hope it helps!
