professor sheng is really nice, i think her class isnt too bad, just practice hard, you will get a good grade

Professor Sheng is a very nice woman, but her lectures were not the clearest. I had taken AP Stats in high school so I had some background knowledge, but she taught certain concepts in a much more confusing way than what I had learned in high school. I thought her midterm was very fair since it was exactly like the practice exams, but it was a bit of a time crunch because we had 1 hour and 15 minutes to do 37 multiple choice questions. The homework questions were much harder than her in-class examples, but they were good practice for exams which included similar difficulty in questions. However, the final was a lot more difficult and I think there was a heavy curve. It was the first quarter in-person in a while and she allowed for 1 page front and back of cheat sheets. The exams had some fair questions but there was also a lot of things that seemed like she hadn't explained. It was a 50 question Multiple choice exam and we had 3 hours, so time wasn't too big of an issue but I did have to guess on many questions that I didn't have time to do. There was also one question that had to be removed from the exam while we were taking it because none of the choices were correct answers so I feel like that wasted some time if people had been working on that one. Someone sent a poll in the groupme after the exam asking how many questions people guessed on, and the winning response was a range of 10-15 questions. Overall, she wasn't the worst professor but definitely not the best.

After seeing all her previous reviews I decided to stand out and make a comment.
I think she deserves better scores than it shows, I would say she is at least an average or above-average professor. Yes, she has an accent, but she is very helpful and caring. She always answer students questions with patience.
Her midterm is very easy, and her final is kind of tough, but doable. My recommendation is to make sure to complete all her previous final/midterm exams and study at the homework for sure. Lots of questions on the exam are taken directly from the homwork/previous exams. Getting familiar with those exams and homeworks is the key to success in this class.
I would recommend taking her class.

Having prior stats knowledge from AP Stats or Stats 10 definitely will help you out in this class. Her lectures are helpful if you have no stats knowledge, otherwise, I'd recommend saving time by taking notes directly from the lecture PDFs that she posts. The midterm is relatively easy, but for this quarter it was open-notes and online. Definitely study for it still by going through the past year's midterms and reviewing homework. The material after the midterm gets extremely difficult as there is some integral work and calculus involved. The final is extremely hard and is often the reason why she curves the class. I recommend extensively studying the finals from past years, even though she says it will be like the homework. It was a time crunch and the first in-person exam for many people which will likely cause the average to be super low. She takes quite literally forever to enter the final grade. We had the scantron exam literally the first Saturday of Finals Week and it is currently the last day grades are due but she has yet to upload them. This is causing many that are enrolled in Econ 103L to be super stressed as it is a pre-req. Overall, the class is very do-able and her notes are somewhat helpful but I am sure there are better teachers out there.

This class wasn't too difficult if you've taken any form of stats before. Only a few of the concepts were new to me since I've taken AP Stats. The lectures are honestly really confusing, and watching her explain concepts that I already knew had me more confused after lecture. I did keep watching lectures just to see her examples, but I'd solve them on my own for practice instead of watching her do it. If her lectures weren't recorded I probably wouldn't bother watching them since they need to be sped up/skipped through to be worth it. The homework is graded easily and the exams are pretty fair.

First half of the class was fairly easy and straightforward, but then she got tough on us in the last half. Midterm was quite easy, but the final was very difficult. Make sure to go to your TA discussions and office hours. Sheng is also very helpful if you go to her office hours. Selling the textbook, contact (707) 391-5443.

Sheng is decent. The material after the midterm becomes a little tricky. The final is hard.

Do not take this class. While Professor Sheng is a knowledgeable woman, she is quite poor at conveying any of that knowledge in a useful way for the exams. The midterm for this class was fairly easy, with an average in the 80s while I earned a 90%. The final, however, was honestly the hardest test that I've ever taken. I got a 46% on it and the average was a 60, and because the class is graded on a curve relative to peers, I got a C+ in the class. Her lectures are incoherent, with her lack of charisma and thick accent making her very difficult to understand. If you can avoid her, I strongly recommend it.

i do not recommend taking sheng. her lectures are very dry; she copies directly from her online notes onto the board. however, i would recommend going to class rather than just following the online notes because she gives example problems in class that are often not included in the online notes. she assigns weekly homework assignments which are based off the lectures (kind of), and you need the textbook for those. that being said, the example problems from lecture and homework assignments are not at all indicative of the difficulty of her exams. i got a 28/30 on her midterm exam after going over the practice midterms she posted multiple times. So, i studied for the final the same way. i went over her previous final exams that she posted a multitude of times. she cut the final time to two hours and we were not allowed a cheat sheet. in the exam, i was extremely pressed for time to the point that when there were 5 minutes left, i just had to randomly guess on like 7 problems that i had skipped. although i felt very prepared going into the final exam, i would guess that i probably guessed on half of the questions.

when the midterm scores came out i was less stressed about the class because i felt confident that i could do well and get an A, however after that final i will be lucky to get a C. i don't know why it takes her so long to post exam grades considering all the exams are taken on scantrons. she still hasn't posted the final grades, and we took the exam on sunday preceding finals week.
