DRUM EXAM!!!

So my mum has been bugging me for ageeeessss to do my drumming exam and she ended up saying that if I don't do it she's gonna stop my lessons. Anyway, my exam is in a few weeks which gives me loads of time to prepare but I am still scared absolutely shitless dude. If anyone has any tips other than "just practice" then ill take them with open arms (and marry you)
