By far one of the best mathematics teachers I've ever had. He is such a phenomenal teacher and has a fantastic teaching style. I love his handwritten homework solutions. He is extremely dedicated, helpful and clear. During SGI, he sat down and went through past problems step by step with me! Also, he has a great sense of humor! He is very reasonable with homework and fair on tests. I would definitely recommend taking his class.

As someone who was really into math in high school i could not have hoped for a better teacher than mr.reutershan. It is extremely rare to find a teacher of his insight knowledge and clarity when it comes to math. In my opinion only, he mr.weng and mr.cheung were the teachers who i felt i could learn from because they were so knowledgeable. Mr.R was also just a really cool dude. A very very chill guy. If you ever lucky enough to have Mr.R be greatful because hes the best teacher i have ever had.

I wish I had had Mr. Reutershan for Calculus at Bx.Sci.--then maybe it would have been much easier and made much more sense. He's one of the best math teachers in the world, and I majored in math in college. I wish I had him there!!!

Mr. Reutershan is AMAZING! Any student of his is truly lucky to be taught by him. He is so smart and clear, and is very, very organized with all of his lessons. He is especially nice and helpful in SGI - he will answer any and all questions you may have. He truly loves and cares for his students. He's inspired me to be much more interested in math than ever before. I have also loved his jokes and his amazing juggling skills. He is the best math teacher I have ever had! I will miss him so much!!!

One of the best if not THE best math teacher in the department. He is very knowledgeable, helpful, clear, and actually is able to teach the class so that they are able to understand math content very easily. He's always willing to go the extra distance to teach someone what they did wrong on a problem and how they should've approached it.

Ratings speak for themselves: Reutershan knows the material (and knows it very well), he's entertaining, which makes the learning process more passive. He'll really go out of his own way to help you. Definitely don't pass up the chance to take any of his classes. Walk into his class knowing nothing, you'll walk out definitely smarter.
