Mr. Callens is the best science teacher I've ever had. He is very easy going and likes to try to adapt his teaching to best soot the whole class from fun/enjoyable understanding. He is social able and some one who you instantly feel comfortable with to open up personally from the beginning and is unbiased.
he was my physics teacher, and he was really good.
Hands down the best science teacher in the school!!!
Revolutionary Extraordinary Sophisticated Unprecedented Stupendous
