I am already doing my graduation and in July, I will be in the 3rd year of graduation. Can I do my Diploma along with my graduation?

Dear student it is my pleasure to help you and give your question in a way so that you can clear all your doubt dear student if you are in the final year of your graduation then you can't do it because you can't attend both classes at the same time and another thing college will not allow you, so it

Yes, you can do Diploma and graduation simultaneously.
