What you're in is the entry level class which subsequently I liked joining because it was easier...haha. Advanced class focuses on combos, major ab work outs + conditioning where you'd pass out, and of course sparring then fighting.
There's no rush for you. People often want to join, but if you don't have the technique down then what's the point. Try it out for a month if you feel you're ready to move up you can do so at anytime.

Baked, not fried... the healthy choice.
