very nice and funny, makes chemistry enjoyable
seems very smart for a teacher, knows not only the topic he professes in, but other ones as well, he explains things understandably. overall a helpful and sometimes funny teacher
he is the best teacher EVER. made me start likeing science! so helpful too and funny.
Great person in general! I love his class, there's always a story or something to talk about no matter how strange it may seem...
awesome teacher, willing to help even if its not for his class. sooo funny. Langco helped me get through high school!!
AMAZING teacher--too bad he is turning into Russenholt's lackey
Mr.Lange - So do you rent, buy, or only watch 15 sec clips? HA! - your friends from S3 physics!
Mr. Lange is really good fun teachen teacher. i think he is one of the best teachers in this school.
an awesome teacher. he was super patient. and was always more willing to help his students rather than discipline them which is the best way to teach.
