As you will pass inter in 2020 as it totally depends upon you if you are going for technical degree then diploma is good as compared to distance because of lab available in some colleges and industry tour but if not technical distance education will be nice if you have sufficient internet connections available and facilities available BUT I would say after 12th doing diploma might be waste of time but nowadays diploma students more light to jobs.

Dear aspirant,

Hope you are doing well. As per your query it depends on what course you want to pursue. Diploma is much better than distance education degree when pursuing a degree in a technical field as you will be able to get more field knowledge. But if you are pursuing any non technical course both will keep the same value. Hope you find this helpful. Thank you.
