If any student is not satisfied with his/her result he/she can give exam after the corona situation is under control as happen in 10 class case.
But is not preferred by me to give exam afterward coz what if you are not satisfied at that time also and it will become a tedious task to learn same thing for so long and will also waste several months to an year of your life.
For now don’t affect your mind by thinking about the future as result has not come and enjoy
