I don't want to go to the army

Yeah, so basically my problem is that in dp1 i got a really bad overall grade which is 29 and that is nearly not enough for me.

My main concern is that if i dont get into one of the top 50 universities worldwide I will have to go the a military service for 2 whole years, and theres no doubt of me dying there or just getting beaten up by other servicemen daily.

Do you happen to have ANY tips on how to pull this off? (Yes i know that i have to study my ass off)
