Hello Pooja,
You have done the Diploma in IT and now you are saying that you are not interested in coding. Okay, there are plenty of opportunities that you have after completion of the Diploma. You can think of taking a lateral admission in another branch of engineering if you want to continue in engineering studies, else if you want to change track, you can think of doing some other graduation based on your Diploma as equivalent to class 12th. It all actually depends on what is it that you want, which subject fascinates you or which subjects makes you motivated to study. You must follow this and study further in this subject for a satisfactory career and life. Best wishes to you.
