Okay I have a lot of thoughts about Prof. Wink. I had him for Math 3A the first time that he taught. I took calc AB in hs and I did very poorly, and I was super worried coming into this class. The material is difficult, and even people who were wizards in AB and BC struggled because of the way he taught it. He loved using proofs and being conceptual instead of plugging in numbers and showing examples. His tests are difficult but there isn't anything that catches you off guard. The only problem is that for the midterms, he doesn't give us enough time so I felt really rushed and I was never really confident with my answers. However, on the final, we had wayyy more time so I performed a lot better. The final wasn't easier than the midterm, we just had more time. You definitely have to be a fast test taker.

He is a very sweet guy, and I definitely would take the class with him again if I had to. He is not very forgiving but he's reasonable and I personally liked him. Tiny guy too, looks like a student when he walks in.

I get why people give him low ratings, but I liked the way he taught. By teaching with pure proofs, he was making sure that we actually understood the material rather than just plugged and chugged. I got a B- (like super borderline C+) in calc AB and I did well in this class.

Taking Math 31B with Professor Wink was an amazing experience. I would agree on the part that he is one of the hardest professors for Math 31B, but he is one of the best ones as well.

Grading
He had two grading schemes and would use the one which yielded a better score for each individual student out of the two.

Scheme 1
Homework: 10%
Midterm 1: 20%
Midterm 2: 20%
Final exam: 50%

Scheme 2
Homework: 10%
Higher of midterm 1 or 2: 30%
Final exam: 60%

Homework
He assigned weekly problems from the exercises in the textbooks which had to be turned in during the lecture on Friday every week. The difficulty level of the problems ranged between easy, moderately difficult, and hard. Though they offered good practice, in order to perform well on his midterms and finals, just the homework problems definitely wouldn't suffice and extra practice of the examples and other problems from the exercises are important. In addition to that, I'd strongly advise to solve his practice midterms and final, and also the problem sheets assigned by the TA (if your TA does)- they're extremely helpful and a great source of practice. Also, he drops your two lowest homework scores and a score of 75% and above on the homeworks is considered as a 100%, so that even if you make some error, you can learn from it and avoid it later on without putting your grade at risk.

Midterms and Finals
His midterms and finals were hard- no kidding. The averages on the first and second midterms were a 50% and 61% respectively, and that on the final was a 63%. But that doesn't mean they were completely impossible to handle. The exams being hard just meant that he really made you work if you wanted to secure a good score. The one drawback with his midterms that I would say is that they were just worth 26 points. So if you made even a small error, that would drop your score in terms of percentages a lot. If you're consistent with practice and don't put off the syllabus for just before the midterms and final, then I don't think you'd have any major problems in performing decently on his tests. The material in Math 31B is much, and a lot of it is in interconnected with each other (for example, you can't move ahead with infinite series or Taylor polynomials without having your concepts of all the convergence and divergence tests crystal clear). That is why it is important that you follow through with the practice and material as it progresses in the class so that you allow yourself to get familiar with it at a comfortable pace, which is really crucial to ensure in this class if you wanna perform well.

Also, Professor Wink gave two points of extra credit for filling out the instructor evaluations at the end of the quarter.

Curve
He said that he wouldn't curve any exams (midterms or finals) individually, but would scale the overall scores after all the exams. The class was scaled down to quite an extent, with the cutoffs for letter grades in comparison to the overall scores being as follows-
100% or above: A+
>=85%: A
>=82%: A-
>=79%: B+
>=72%: B
>=69%: B-
>=64%: C+
>=53%: C
>=43%: C-
>=33%: D

In all, I'd definitely recommend someone who loves to learn more about the intricacies of Math to take Wink's class because although it is hard, you learn a lot and get used to taking difficult tests. He does a great job of preparing you well for harder classes to come along.

Had an okay experience with this class. Exams were tough - fast-paced and peppered with tricky questions. I mostly learned from the textbook; I definitely don't think I could've gotten by using just lecture material. Wink is helpful in office hours and scaled our homework so that it was easier to get full points on them even if you didn't get all the questions correct. He also gave two extra credit points at the end of the quarter for filling out his instructor evaluation.

Overall, not a bad choice for a prof, but you will have to put in a lot of your own work to do well.

The Professor spends more time using fancy words than he does in teaching. Overall, a decent teacher. Midterms and finals are hard though.

This was his first time teaching 31B. He's still learning how to teach and explain stuff but he was a decent teacher. He's sometimes hard to understand but he follows the book closely, will answer questions and seems like a nice guy. Hard but fair exams and he curves grades at the end of the quarter.

Finding a professor for this class is like finding the lesser of two or three evils. Wink is helpful if you attend office ours and do all his practice problems. The class is just generally challenging, but I feel like Wink was a good professor

Not gonna lie, this is a tough class. But I really like how Professor Wink presents the material; he shows a lot of "proofs", if you will, to show why theorems are true. This really helps for a deeper understanding of the material, and is great if you like math (Professor Wink is from Europe, where apparently math is taught from a more proof based perspective, whereas here it's more about computations-- you can take that how you will, but I really liked the different perspective). Sometimes lectures were difficult to understand, but he takes questions very well. And at office hours he's incredibly helpful. Very patient and thorough.
His lectures also follow the textbook quite closely, so if you're stuck from lecture it helps to review the book.
Do all the homework! Even the extra problems you don't have to turn in. Personally, I had do a lot more practice than what was even assigned. My advice is do as much practice as possible.
His tests are quite challenging, but honestly pretty fair. Took me a while to get used to his style of problems. My experience is that sometimes they're more doable than I thought they were. But sometimes you do get a really tough problem, which is life.
All in all, great math class.

Wink is still very new and learning how exactly to conduct class so this review may not be useful a few quarters from now. However I would say he’s a very average professor in his current state. Not anything great, but not bad. It’s not a hard class, but it’s not easy. The workload isn’t too bad, but it’s not super light either. The class was perfectly average.

His lectures are super proof-heavy and not very helpful. I ended up skipping lecture most of the time and studying from the textbook as his notes are straight from the textbook. Know the material inside out for the exams because there is just enough time to finish the exams and do all the practice questions he gives out. Overall, he is a nice guy and very receptive to questions but since it was his first quarter teaching at UCLA, he really did not know how to explain anything.

Wink is a very nice guy who's receptive to questions in office hours and will repeat the material until you understand the topic (He's fantastic in office hours. Super clear and understandable). Lectures, however, were a whirlwind. I know some people that appreciated Wink's structure, but I quite frankly did not learn much from lectures because he would mostly do proofs. As such, I pretty much self studied the whole course through the textbook. Wink's exams admittedly are fairly hard and you have to do a lot of practice problems to do well in them . I honestly thought I was going to have to retake this class based on my midterm scores but revamped the way I studied for the final, and ended up doing okay especially given the fact that I had a D going into the final. Would take again. 7/10 experience.
