Absolutley Awful. Handwriting is Illegible, cannot explain topics well at all, tests are out of left field, constantly goes off on tangets, all examples are from insurance company. DO NOT TAKE.

Used to love Calculus, but this course made me hate the subject and feel as if I unlearned the material. Only a few tests and he doesn't input grades as they come so you have no idea what you have. Reviews are 10x easier than the tests and don't prepare you at all. His notes are unorganized and hard to follow.

He makes me feel anxious because he'll do problems on the board and then blank out, so then he tells us to do it as a challenge and we never talk about it. The way he tests grade is weird, when we go over the practice he says its ok to just put the answer, however when we look at the real test points are taken off for not proving or simplifying.

Lectures, homework, and tests are based on three completely different groups of information. Kind of whiny and off-topic a lot. If I hadn't taken this class already in high school, I would have failed. Promised curves on midterms when the class avg was poor, then at the end of the semester, claimed that curves were unnecessary and never promised.

absolutely terrible. If you haven't taken calculus before then you will fail, or will need a tutor. whenever he teaches he assumes you already know many of the topics so he will skip over many of the fundamental calculus laws and rules that you need to know. lectures are very boring and will leave you more confused than actually learning. DONT TAKE

Will literally tell you to "pull a function out of thin air," say that you will get the hang of it, and never actually teach you how to do it. If you don't write, verbatim, what he said in the notes on a test, he will take off most points for the question (even if you got it right). Also awful at explaining things if you ask questions in class.

Clark is a terrible teacher. He doesnt explain anything and gets randomly sidetracked all the time without explaining where hes going with it. He expects you to know things he hasnt taught and remember every random function he mentions. Hes very monotonous in lectures. He is terrible at answering questions. I would not recommend taking him.

I would avoid taking 408D with Clark unless you HAVE to. It takes an intense amount of concentration to actually learn any information during lecture. He teaches by doing practice problems, while barely/quickly explaining them in a monotone voice. Plus, his tests/homework are also difficult and he doesn't care if the class has a failing average.

I hate writing this because Dr. Clark is really a considerate person, giving HW extensions, make up dates, and so on, but his lectures are difficult to follow and the homework (Quest) is tedious. However, the worst part has to be the midterms. They are way harder than any of the review midterms, and you lose ALL your points if you are slightly off.

By far the worst professor I've had at UT. Extremely poor lecturer, exams that are consistently more difficult than the review sets (with averages of 60), quest homework. Wrecked my GPA. Thanks.

A math professor that cannot teach to save a life. Lectures and homework are beyond useless. Point is, do not take him.

Learned more once I started skipping and learning on my own through Paul's Online Notes. Tests are difficult (class averages were around 50-60). One time he went on a tangent about how he throws rocks at pigs in his driveway (came from predator-prey scenarios). Don't take unless you want your GPA to get wrecked. He curved final bc everyone failed

He is awful. Lectures suck, he doesn't care about anything other than going home. Spends half of lecture ranting about something else. Does not clearly explain anything. Handwriting sucks. Does not care if the students fail, will not budge on anything. Homework assignment every other day even if it is short. Skip this man if you want to learn.

He's a terrible teacher. He's a nice man but so smart he'll skip over many steps when solving problems and will do example problems in 15 seconds then talk about insurance for 35 minutes. Wouldn't recommend unless you have a solid background in calculus, and even then you may struggle.

Dr Clark is a terrible teacher. His lectures are dull and he speeds through examples with little explanations. I learned the most by going to TA office hours. He gives so much homework I could barely keep up with the homeworks in my other classes. We got about 3 homeworks a week for a total of 36 homeworks throughout the entire semester.

Probably the most boring lecturer I've ever had. Textbook is useless. He also gives a ton of homework. The TA wasn't very good either. His grading system is fairly nice and the tests were only slightly difficult, but this was probably the most bored and uninterested I've been in a class at UT. Wouldn't recommend taking him.

Dr. Clark is a very boring, uninterested, dry lecturer who lacks teaching skills. Did not go to many lectures after first midterm. Class itself is not too difficult, you have to do a quest homework (harsh penalties) for each lecture and weekly quiz. Don't be fooled by the grade distribution, because Dr. Clark ruins the beauty of college math.

I took this class in high school and did perfectly fine and understood the concepts. Professor clarks class was completely different. While I did understand the topics and how to do the assignments he would always put the hardest and weirdest problems on tests. Quest assignments were brutal if you missed even one question. Avoid Clark if possible!

Professor lectures in a way where it is difficult to understand, rarely stays on topic and talks about his unrelated experience in the business sector. Is rarely helpful in office hours and will not curve the 2 points you need to pass the class. Class is a waste of time, CC classes are more involved. Waste of time skip this man.

One of the worst profs in the entire math department at UT, and that's saying something. If you get put into his class (math department doesn't tell you who you register for), drop. Seriously, drop and pray you get into another class. He is a terrible lecturer, and the TA is the only saving grace (thanks Chandel). He doesn't use +/- thankfully

I cant even get started. This class is online and after knowing and studying every concept front and back, the open book final exam was still impossible. I saw the reviews were not so good but I still had to hope. Never again. I passed my AP Calculus exam and knew every concept but the way he teaches is so poor. SKIP HIM

Dr. Clarks lectures are useless unless you want to listen to him crack jokes and ramble about life experiences. In the words of Clark himself (three days before the final by the way) I wouldnt recommend 408C for people who havent taken calculus before OChem was easier for me than this course.

I stopped attending lecture after the first week bc he teaches so poorly and is so disorganized. The TA was a life saver! I don't recommend him if you didn't take calc in HS

I am conflicted, because Prof. Clark, is a really nice and knowledgeable man. He is smart, but a poor teacher. If you dont have any experience of calc, be prepared to teach yourself. Exams/HW are nothing like the examples in class. He did give a nice curve though at the end, but thats also because so many people failed.

so many people failed the final, luckily he gave us extra credit the day grades were due. his lectures are worthless, you're better off learning by yourself, a TA, or Sanger. Tests and practice homework were never alike, but he gives a lot of time for you to complete them.

AVOID THIS professor, at all costs. His lectures are not helpful and very difficult to follow. Exams are hard, and the questions are all free responses. Probably the worst math professor here at UT. The only thing that saved my grade was the textbook.

Not a good lecturer whatsoever. You WILL have to read the textbook or else you're likely screwed because (once again) you learn nothing in his lectures. HW after every lecture. I would avoid him at all costs for Probability I and take someone else.

Do not take him. Run. He is not good at teaching.

He is very knowledgeable, but he does not do well teaching the material. His lectures are hard to follow, but he does answer questions.

I took this class in high school, but I have no idea how someone could pass this class if they didn't take it in high school. His lectures are very boring, and doesnt explain the material. He just writes the material on the board. The only reason I passed this class because of the TA in the discussion sections. She actually helped us understand.

DON'T TAKE THIS PROFESSOR. I got a 5 on Calc AB junior year; thought it'd be an easy review class even though his reviews sucked. I was so wrong. Do yourself a favor and drop. If you can't, watch lectures by zoom and do all the practice midterms he posts before the exam - they're the exact same format so if you can do those problems you'll get by.

He's awful. I honestly don't know how anyone could have anything positive to say about him. I taught myself the course through chegg and youtube videos. I did fine, but it would've been much less time consuming to have a good professor. It is 100% worth the trouble of switching teachers, especially if you're taking other hard prereqs like I did.

I came into this class with a strong base in calculus 1 and 2. The only reason I survived this class was because of my prior experience, and even then it was painful. You would think this class would be an easy revision, perhaps an opportunity to practice and gain experience. However, I LOST experience, I unlearned. TAs will carry.

A fun guy and talks a lot about his existential crisis of working at UT and wanting to become a professional rock thrower, but his lectures are boring and painful. I took calc in high school, but he has helped me forget everything I've learned and made sure I am not ready for the next math courses I will take. A lot of self-studying is necessary.

Hes a smart guy, but hes very big on proof. 90% of the lectures are him proving his work. His homeworks are not made by him, even he struggles with doing the homework questions. definitly would not recommend him at all

AVOID. Only did well because of prior Calc classes. Worst professor I've ever had. Lectures were completely useless but attendance was still mandatory. Everything I learned was through YT or our TA. Never gave the slightest hint of what would be on exams. All my friends in other calc classes were doing much better. Look for a different professor.

David Clark is very knowledgeable and intuitive about the topics he teaches. However, I would never take his class again. The lectures are useless, and the homework is nothing like the tests. The one saving grace is the practice tests, which you can use to teach yourself the course material, as well as how the tests work. FIND SOMEONE ELSE

Not only is David Clark's class not helpful, I actually leave feeling like I know less than when I walked into class. All he does is confuse everyone. The homework is said to be on a "guess and check system" however it WILL put you into the negatives if you get one question wrong. Like my grade has gone up by NOT doing the homework. Transfer out.

I wouldn't wish this professor on anyone. His job is to teach and he fails at it so bad that he confused students with prior Calculus experience. Look for someone else.

by far my worst professor this semester. i had to learn everything myself. take somebody else if you can

I feel like the material was difficult enough, but having Dr. Clark as a professor made it so much worse. He's dry and boring, and convolutedly explains everything. Tough grader, the only reason I passed was bc of our TA. I should've Q dropped this class

Clark is probably, if not the worst professor/teacher I've ever had in my schooling career. He's very intelligent, but lectures are basically useless. You will most likely have to teach yourself 90% of the course material. 3 quest assignments a week, two midterms, and a final (tests are 77% of your grade). Do not take for the sake of your sanity.

Worst prof I've ever had. Lectures are mind-numbing and useless, I learned everything from khan academy. Homework is often due before material is covered, and wrong answers result in negative points. Exams are difficult. Clark gave extra credit and a generous grading scheme, but that does not make up for how genuinely terrible he is at teaching.

Moderately difficult class. Clark has to be the MVP when it comes to giving monotone lectures. That said, he did give us corrections on the first two midterms; but then on the final, he gives neither corrections nor a curve. Homework was assigned 3-4 times a week resulting in 36 problem sets. Moral of the story: get Blazek if you can.

Worst class I've ever taken. The lectures are extremely monotone and boring to the point where its impossible to focus. 36 homework assignments, 15 discussion quizzes, over 30 learning modules. Don't take this class, get a different professor.

He made us memorize all formulas for practically every distribution (literally dozens of formulas, totally pointless, and made everything 100x more difficult). The final took my grade from an A- to a C+. All of my studying was spent on memorizing formulas. Avoid this passive-aggressive incompetent professor for the sake of your sanity.

Worst lecturer Ive ever had, he makes going to class feel like a waste of time and doesnt explain concepts big picture. The textbook for this class is really helpful and he is a generous grader, but dont expect to learn from lectures. This is a hard class but if you put in the work you can do well enough on the midterms and final (90% of grade).

Absolutely horrendous. The worst professor I have ever had hands down. This is literally my first time ever posting a review for a professor because I am usually pretty understanding. The dude is extremely incompetent and is literally blindly copying from a paper onto the board with no shame. Terrible handwriting as well and cranky for no reason.

Worst professor I have ever had.

Impossible to learn from the lectures. Impossible. Rambles at length, scribbles random stuff on paper, doesn't explain anything. Unless you already know everything in this class, don't take this professor. Having to learn this alone is terrible.

Class isn't too bad, i ended up pretty much teaching myself everything because this guy is a stunningly bad lecturer. Boring, messy handwriting, doesn't explain stuff well and goes into detail on things that aren't relevant. Nice guy though.
