I thought he was very helpful; when someone struggles, he's patient with them, and will help them as they can.
He was one of the top three teachers I've ever had.
He's my favorite. Smartest guy ever and super funny.
He's the smartest teacher at South, he's good at explaining, but overall it's not the easiest class. He also has some really good nerdy humor.
the brightest guy i've ever met. He has so much nerdy humor,
i expected a hard class, but the way he taught everything made it fun and interesting. it was all so clear for me... he's an amazing teacher.
He has to be the coolest guy ever!! He is so smart it is insane! i love all his funnys in class! hes a really good teacher!

I LOVE Mr. Walstra. He never gets mad. Everyone respects him. He is incredibly smart. He makes physics SO SO SO Interesting! My favorite class now!
He has hard classes, but if you try you can do good. Easily the smartest man alive, and super-cool. Laughed when me and buddies made fun of annoying people
