Bondarenko is/was probably the best physics instructor at UCLA. Every lecture is prepared impeccably, and notes for each lecture are promptly uploaded to CCLE. I would've liked a bit more demonstration (that Prof. Kusenko is known to do) though.

One tip for exams. Try to keep intermediate values be expressed in terms of variables, and only plug in variables at the end. This reduces the time needed to punch everything into the calculator and subsequently copy it back to paper. I didn't do very well on the first midterm (ran out of time), but after I noticed that's what he does in lecture, I did pretty well on both the second midterm and the final.
