Doc mandresh makes one of the hardest classes tolerable, he is very knowledgable and gives so much of his time and effort into helping his students. One of the best teachers I've ever had.

it is an astonishing story how a donkey worked hard to live up to human standards and become the best teacher ever. Mandonkey is the best teacher in Riverhead, even if he is a mule.

Mandresh is without a doubt the best teacher in the school. Definitely request him if you're taking Chemistry.

The rating below me is Louis Ambrosio being upset he cannot win in arguments to Mandresh. I've witnessed it first hand. Mandresh knows how to teach well, and how to stump Louis 59 times a day.

He is probably the best teacher ever. He will also never win in an argument to Louis Ambrosio.

Mandresh is the bomb! Jokes around the class, makes it super easy to understand Chemistry, and wants to generally help everyone in that class succeed. Definitely taking AP Chem next year.
