[@Dragonite777] Ahh. for HS we're only allowed to have 2 events and 2 relays each, due to the order of events I'm usually in the 200 free, 500 free, and 4x100 freestyle relay. 
As far as USA, we have a max of 10 events and 2 relays over the course of two days... The ones I'm in can vary extremely depending on what I still need to qualify in for states.
As a test once my coach gave me what he called "the cruelest set of events ever" at one meet: 400 IM, fly leg of 4x100 medley relay, 200 Fly, 200 Free, 200 Breast, 1650 Free the first day; 500 free, 200 back, anchor leg of 4x200 free relay, 200 IM, 100 fly, 1000 free, and then exhibition for the 50 free because they had an open lane and I (my coach) wanted to make it an even 5000 that I had raced at the meet. So yeah. I did 5000 yards of racing in a 2 day meet... I told my coach that he should have just crucified me if he wanted to kill me. XD He let me off the hook for a while after that.
