Comment:
I took him for data analysis 1 and it was rediculous. I don't even have trouble in math but his class was impossible to follow. It started out ok, but by the middle I was lost and so was he! He never seemed to know what was due and kept changing the format of the class. If your good at math, then you might be ok, if not avoid him.

Comment:
I am a senior here and I took this guy in my second to last quarter. I attended all but 2 classes and still have a very vague idea of what was taught. I don't normally post on these sites but I'd like to help my fellow "average at math" classmates and tell them to avoid this guy.

Comment:
If you're taking him for lab, it should be pretty easy as long as your taking a different teacher for data analysis. As for him teaching data analysis, stay away! When I walked into data II with him, I was so confused- not willing to review old material or do anything to help clarify his poor notes and instructions. I dropped his class asap!

Wish I would have listened to everyones advice. This guy is by far the WORST teacher I've had at RIT. His notes and lectures are extrememly unclear, he refuses to use mycourses, so he randomly posts assignments without due dates on his own website. Probably going to withdraw from his class. do yourself a favor and DON'T take this guy.

Comment:
Don't ever take him! GEEEZ! His breath really stinks so I try my best to avoid asking him questions because he'll lean in and try to breathe in your face. Not only that, but he is totally unorganized and lost so many of my papers and forgot to give me a couple of instruction sheets so everything screwed up this quarter. I got an 'incomplete'.

This is a cakewalk class. Said if you do the work, you will get an A. He was right, generally a helpful, but don't take his bluntness personally, thats just him. That is how he tries to help you.

Very hard to understand...gives you a packet of notes which dont help that much...projects are kinda tough and doesnt explain them well...tests are not too bad, but can be tricky....does not explain the material clearly....would not recommend him
