That's about all the little easter eggs the town of Balamb has to offer up until this point. When you've explored to your heart's content head on back to Balamb Garden. If you follow the road you won't encounter any extraneous monsters. If you're in the market for some XP and quite possibly some items and/or cards to refine into great magics, however, you can hit the beach and try your luck with some more advanced beasts.

Once at Garden, head towards the atrium and Directory. Along the way, be sure to hit up the Cure draw point again, and if you're interested, the man at the turnstiles has some pretty good Cards. Once inside, be sure to speak to Xu, Cid, and Quistis. When you're finished, head off to the right and speak to a moping Seifer. After a brief cutscene, head back towards the directory, save your game, and go up the elevator to the second floor hallway. Speak to everyone in the hallway and wait for the cutscene where Squall's (and Zell's) names are called for passing the SeeD exam.
During the short and sweet inauguration Cid will say a few things (you'll notice Selphie is also one of the passing students). If you get the feeling that he is being strong-armed by the Garden staff, good job picking up on the nuance. You'll find out much later what is really going on here - and it is all part of the intrigue that makes this game such a pleasure to play. Be sure to talk to Cid after his truncated speech to receive the Battle Meter, which you'll be able to access from the menu.
