I have no idea why she has such a bad review for 125, but my experience in 115 was very good. Her lectures were very engaging, and she clearly knew her stuff when teaching. Maybe she just got better at teaching, or she is better at teaching 115.

Regardless, the class is very similar to 106, since they are both reaction classes, but this class does cover different things; namely this class has a far greater focus on enzymes. For undergraduate students, the grade breakdown was the following:

Exams 1 and 2: 20% each.
Final: 25%
Homework Quizzes: 20% total, with 5 of them
Group project: 15%

The exams were somewhat harder than the homework. Instructions on exams were somewhat unclear, but for the most part, they were mostly fair. BE WARNED: YOU CANNOT MATH YOUR WAY OUT OF THIS CLASS! For exams 1 and 2, 40% of the points were from conceptual questions. Therefore, know the concepts, and know how assumptions made affect the questions.

The final was 100% cumulative. About 10% of the final was from conceptual questions.

Homework in this class is optional, and there were only five of them, with four questions each. However, each week, there is a homework quiz, with one of the questions from the homework. Generally, if you need to graph something for a homework question, it will not be on the homework quiz. So for a given homework problem set, of 4 problems, 2 will be graphing, so one only really needs to do the two non-graphing questions. Even better, Yuting would go over the homework before the quizzes, giving everything but the final answer. That said, one gripe I have about this class is that homework requires Tuesday and Thursday material, but the homework quiz is Friday.

For the group project, it really depends on your group. Fortunately, we get lots of guidance, and the presentation seems to be graded leniently. And for the overall grade itself, I was surprised by how leniently they graded; I thought my grade would have ended up a lot worse.

Also, the textbook is both easy to pirate, and when I took the class, the TA pirated both of the textbooks for us.

As the previous review mentioned, this class did seem to be better than C125. Annabi is overall a nice professor who does seem to care for students. She sometimes isn't the most engaging or best at teaching, and her lectures just got the job done in terms of delivering content and solving examples. There was homework pretty much every week with problems that felt harder than those done in lecture. The midterm also felt that way but the final seemed to be a bit easier. There is a group project component which needs to be improved. Although we got greater guidance than in C125, directions and topic selections were still pretty vague. Overall, a generally positive experience which could be improved.
