I fell asleep in most of the classes, but I managed to get an A by reading the textbook and doing practice problems. He teaches straight from the textbook, and his tests cover numeric problems and proofs that were performed in class on identities or transformations. He's not the greatest teacher ever, and I wouldn't recommend taking him. However, if you're like me and you're stuck in his class, you can manage to do well.

very good

I second that the calculations were insane on the final. So many radicals as components of vectors that we needed to normalize again... and again. I love math classes, and am also taking honors multivariable, but this class was boring and frustrating - even though he showed us the proofs, he never explained why anything was happening. This class is fine, but not ideal. Good luck!

Angelopoulos actually dicked me every class with super long, boring proofs, nothing like what I expected out of my first math class at ucla. This man is the real greek freak. Super helpful in reviews and office hours tho, gotta give him props for that. I worked hard for the final and salvaged my grade (which was about to be a C), so its definitely not impossible to get an A.
Bottom line, try not to take him, but if you do, work hard from the onset.
