Hello Aspirant,

Hope you are doing well!

Well dear,technically you should be a 2019 pass-out since your academic year ended there and for the backlog,it should be mentioned cleared in 2020,but there are different rules for different universities,Hence,getting in touch with a good senior who has a better idea of your institution would be great,as you can ask  more about your university backlogs from them as they have seen more such cases and situations.

Hope this was helpful!

All the best!

Keep Smiling :)
