Can i do graduation course after my diploma?

If you have a 3 year recognised engineering diploma from state polytechnic colleges, you will be eligible for lateral entry admissions to a B Tech programme if you clear state level lateral entry eligibility tests

Dear Subrata, 1) Check with some UGC approved universities with the basic eligibility required for UG courses. Consider Distance learning universities. 2) If your diploma is not eligible (i.e generally most universities need 3 years regular diploma, equivalent to HSC) then pursue HSC and go ahead

Yes you can do graduation after diploma. Good Luck.
