He is a very good teacher but the course is very hard and you must pay attention. Don't be afraid to ask for help he wants you to succeed.

he seems like a cool guy but he doesn't seem to know what he's talking about most of the time so it makes it really hard to learn. it's a hard class and as teacher he just makes it harder...

Very unclear.Did barely any labs the whole year.Paid $40 lab fee and most labs were about boiling water. Where'd the rest of our money go? Not the typical HS Chem experience.

Subject is hard, but Mr Leach does a good job of bringing the material down to an understandable level. Explains things slow and clear. I liked the class.
