Hello there

Simply if I would say then you will be 2021 pass out candidate. Don't worry for the thing that when you will be going anywhere in any interviews then they don't generally ask you when you started your course,unless and until they didn't ask the marksheets of a lower semesters.

So you have to state yourself as 2021 pass out as the same will be on your marksheet too.

I hope it helps you!

Thank you!

For this case you have to put 2021 as the passing year because in 2021 you are clearing all your backlogs and officially you are passing the whole course work from the university/college you have studied in.

I hope this answer helps. All the very best for your future endeavors!
