How do you feel about exponents so far?

• I'm a master, give me a real challenge!

• I'm getting there but still need some practice

• I feel okay, they're kind of confusing

• I don't really understand, I should probably check out tutoring with Mr. Studiner Mondays & Wednesdays 2:30-3:30 or Mr. M Tuesdays-Thursdays 3:00 - 4:00.
