It's definitely going to be difficult to train for; my last final is on June 9th. Tournament is on the 12th. I have 6 Pokémon to train to high levels, not including IV breeding and EV training as well as testing. Those three days between finals and VGC are going to be very, very tough.
I can't do anything now; theoretically I should be working on a paper for Film class and a database for Computer tech, and my team that I'm entering is still in the works. It doesn't help that Shoddy doesn't support double battles yet...
Btw, you got HG/SS?
