Mr. Sierra's a good teacher. Yes, he does have favorites, but as long as you do your work, you'll learn alot.

Mr. Sierra isn't "mean." He's actually just PICKY. He doesn't like people who talk constantly in class and don't get their work done. Probably why i was on his bad side this year.

Mr. Sierra seems mean, but he really isn't. He's a good teacher overall. I really learn a lot in his class, and he makes me want to pursue art more.

He plays favorites, and is extremly blunt. He acts as if art is the only class your taking.

I like his art class because it's very fun. He has high expectations though, and that can hurt your grade in the long run.
