Took him for 131A. Avoid this professor at all costs.

The midterms and final are doable. However, the material itself is already very difficult and this professor did a horrendous job of teaching it. All of the lectures were him mumbling incoherently, and it is extremely hard to understand him through his accent, making it basically impossible to learn from lecture. In addition, after writing something down on the board, he will often erase it immediately rather than erasing something he wrote earlier.

Out of the ~40 people who were in this class from the beginning, only 9 people, including myself, were showing up consistently during the last few weeks. That's not a typo. Several of them dropped out, as evidenced by the grading distribution of the final showing a paltry student count of 22. The averages for the midterms were around 50-55%, and presumably the only reason the average for the final was higher was because of the lower student count. The only reason why I managed to pull a reasonable grade in this class was because of the TA's much more helpful discussions, though unfortunately one discussion a week doesn't make up for 3 whole days of inefficient lecturing.

If you're a self-learner, you may do well in this class. But otherwise, choose a more well-known, competent lecturer instead of this guy. He is the absolute worst lecturer I have had at UCLA and doesn't deserve to be teaching at all.
