HI ASHISH,

There would be a supply exam later during April if i am right. You can write that exam but your result would be announced later.but try to avoid taking leave that would be the best thing you should do.I personally suggest you not to get into trouble by taking a leave during exam dates. But if it's so urgent there would be solution for that. Inform your school authorities if you are doing that.

You absent during exam the another option is you can give the exam during compartment exam in June July session then result will be announced in August this year.

So, you can save your year

THANKS!
