I don't agree with the other reviewer at all from this quarter, aside from them calling out the TAs for having useless discussions (that part is 100% true).

The distribution was 15% homework, 35% midterm, and 50% final, which seems daunting, but given that there weren't any surprises on the midterm or final, it was completely fair. Jin was a fantastic lecturer. Her derivations, while very drawn-out, were very helpful in giving you an in-depth explanation in where the equations came from, and what assumptions were made to arrive at different conclusions. Homework was definitely tough and took a long time to complete, The problems were very similar to example problems she went over in class, but with a twist that was sometimes hard to see at first. But Jin was always extremely eager to answer any questions I had. She was willing to stay as long as I needed after class to help me figure out all the minutia. Additionally, she was very responsive to emails. Tests were very fair; they were definitely more on the time-crunch side, but if you fully understand every homework problem and every example problem, you would have no problem finishing on time and scoring well on them. I did spend about 10-15 hours a week on this class, so don't expect it to be a walk in the park. But if you are willing to put in the effort and spend additional time outside of the class reviewing the notes and example problems done during lecture, you will definitely be successful.
