    I think that Mr. Colosky provides good in-depth explanations for formulas and problems, which I think not many math teachers do unless their students ask. Mr. Colosky isn't the type to just give you a random formula to memorize; he always wants to make sure that his students actually understand the logic behind the formulas, and I think this is what really helps me remember and grasp the concept more. Of course, the website isn't always perfect; there will be some glitches every now and then but overall I've learned a lot more from Mr. Colosky than most math teachers.
