i appred for 12th exam(Gujarat state board) in 2010 but got less marks in that exam due to which i decided to cancel my result and gave 12th exam again in next year as a repeater student so will my 12th will be considered as full time or part time ? and what will be my passing year
If you are preparing Gujarat board in 2020 and will appear for Board examinations in the March 2021 when you are passing your would be considered 2021.
Now coming on your another question that you will be e considered as a a full-time 12th student.
But if you do not want to to do so then you can apply as an ex student so that you can continue your study as well as your another work.
