Hello,

IMO or International Mathematics Olympiad is a mathematics-based examination conducted each year by the Science Olympiad Foundation (SOF).

It is advisable that you appear for the examination on the date you are alloted. Also it doesn't seem feasible for you to appear at a date of your choice or the one that suits you.

Also, you can contact the SOF team and dicuss your issue with them. You can read information about IMO by clicking on the link given below-
