Prof Wei's class was a horrible experience. Lectures were confusing and she would often speed through her lecture slides. Homework was managable due to unlimited tries. Midterms (2 worth 20% each) were challenging, but the Final (40%) did not resemble her "Final review" whatsoever and left me lost. Overall, self learning is a must, and take CLAS!

Avoid unless you have no choice! Pretty much a self-taught course because lectures are useless and hard to follow. Concepts are actually simple, but become really hard to grasp when you aren't taught it well! HW is doable and problems are fair, but did horribly on tests despite feeling confident about the material and attending CLAS every week.

Closely all the grading bases on exam. No easy point. Tough grader. Weird lecture.

** rating for MATH 4A. Wei is extremely difficult to understand during lecture. I completely self taught myself linear algebra, & going to CLAS saved me. Her lectures are useless. Midterms are 40% and the final is 40%, with the other 20 being HW -- ridiculous grade breakdown. Also did not inform students of the letter grade breakdown as it was TBD

The weekly homework in this class is tough; you get unlimited chances though. The biweekly quizzes and the midterm are similar to the homework, but then the final absolutely murders you, and shell curve the final grade down. For my class she didnt drop the lowest quiz/hw grade on time, which left things on an irresponsible note.

Prof. Wei changed grading eventually and I got what I expected. Lowest scores were manually dropped, and grades were given fairly. So to be fair, I think the overall course deserves 3-4 out of 5. But I'm not sure if grading would be tough next time.

The final was so unreasonably difficult. It was nothing like the practice problems in the textbook, the homework, or lecture examples. I got so many points off because of tiny errors and it really messed up my grade. Also what kind of professor curves down?

I didn't even know curving down was a thing until I took this class. I took this class during COVID so it was much more difficult to concentrate, however I did not feel that I could learn a lot from her lectures anyway; everything I learned was on my own. I seriously do not recommend, not even as a last resort. Take it at a CC if needed.

A pretty good professor overall. The down curve and not dropping the lowest HW score initially caught a lot of us off guard but I'm glad everything was fixed in the end. Quizzes and midterms are similar to lecture problems and HW is on webwork with unlimited attempts. Honestly one of the better math profs, but be careful of the grading scale.

She is a good professor and is knowledgeable. The accent isn't a problem for me at all. She adjusted the grading scale because the class average was too high for her. She also didn't drop a hw like she said she would on the syllabus. I feel like most profs try to accommodate student's needs during this pandemic but she did the opposite.

Lectures are great, quizzes and homework are not difficult. I messed up my final so I expected to get a B+ (I got my homework and quizzes around 95%), but she messed up grading. She didn't have time to drop the lowest score of homework manually, which she promised in the syllabus; and she didn't make up for our loss but curved down (95+ A, 90+ B)!

Terrible terrible terrible. Curved down the entire class a ridiculous amount. To get a B you needed a 88%. Can barely understand her because of the accent, does not communicate with students, and even changed her mind about the syllabus on the last day grades were due in a way which hurt her students. Do not take any of her classes

She's a great lecturer but really messed up the entire class with grades. The final was significantly harder than anything seen in the class (not even sure we learned some of the stuff), she didn't follow her syllabus and drop assignments, and curved down the class! Still have no idea why profs punish students for doing well. WOULD NOT RECOMMEND

She's pretty good throughout the semester. Quizzes and midterms were straightforward and easy if you know what you're doing. Final was much more difficult, and she curved our grades DOWN. If you want an A be prepared to score near-perfect on every test bc she might lower your grade.

Class was pretty straightforward material wise. However, the professor is terrible. I did not understand anything from her lectures. She also rounded everyone's grade down. She also said in the syllabus she would drop the lowest hw but did not live up to that promise. The rounding down is completely unforgivable since I earned my grade.

Frankly say, professor Wei did a good job in Math 4b class. Her accent is not a big problem and she covers every question raised by her students. Accessableduring office hour, and offers a lot of help to solve student's confusion. Students are graded by homework, quizzes, mid and final. Trust me, listen to lecture carefully and these won't be hard.

I did great on quizzes, hw, and the midterm. I was expecting at least a B but the final was so much more difficult, compared to everything else. Did not drop lowest hw score either, even though stated in syllabus. I learned more form CLAS and section than the actual lectures.

From previous reviews, I was scared that Prof. Wei's accent would be an issue but her accent is actually ez to pass through/understandable. You get 10 questions per homework (rare to see limited attempts) per week--aka a chill class in terms of workload. Her bi-weekly quizzes are straightforward & if you took calc bc, this class is a good review!

Don't use the practice final to study, you pretty much have to know everything from the sections in the book. Final was one of the hardest finals I've taken at UCSB. Don't think she curves the class

Midterm was easy, final was awful. Her lectures are difficult to understand and she gets frustrated with questions in office hours, but is sometimes helpful.

Class was not structured well. First half was too slow and midterm was not too hard. The last two weeks were completely rushed and I felt very unprepared for the final

Her accent isn't significant, she's very easy to understand if you're paying attention. She explains the proof methods clearly and I learned a lot in her class. Tests were the same difficulty and topics as the homework, which is turned in weekly and graded for correctness. The required written homework helped me really learn all the topics.

Wei is an excellent professor. Her lectures teach students important theorems from the book and proofs her gives are clear and easy to understand. Although attendance is not mandatory, one should not miss her lectures. Final is largely based on homework and not hard at all for students who carefully finish their homework with their own effort.

Wei is one of the better upperdiv professors. Her class is tough but she is very willing to help students and listens to feedback -- she won't just brush you off if you're struggling. There's 4 pop quizzes each quarter, and she assigns quite a bit of homework but in the end you'll definitely learn the material. Her tests are tough but reasonable.
