His 8:50 am classhe's a bit unclear in his lectures and kind of lazy to help students during lecture, but if you take his class at 1:20 or later, he seems to put more effort into teaching the material and helping out students during lecture. (his lecture class size isn't like normal lecture sizes, it's substantially smaller but not classroom size)

He is so good. He helps students a lot and he has office hours every single day. His tests are not hard and he is genius. He is my professor for math 221. I highly recommend him.

His lectures can get annoying at times because his mind seems to jump from one thing to another and he is very awkward. The lectures can get confusing because of his awkwardness and fumbling of words. Other than that, he is very helpful and will try to help any student he can. I would recommend him. He says "I mean" "I don't know" and "um" a alot.

Dr. G's lecturing isn't always the most clear and he is really awkward, (be prepared for a lot of: um, but anyways..., you know... etc.) but he does well enough. He is very helpful, and makes you think. He gives helpful hints on what to do. The group projects felt a little pointless. Take him if you can with the five lecture a week format for 221.

Super nice guy and is pretty good at explaining math. I had him for 221 and he grew on me throughout the semester. Wish I could get him for 222 too :(

Dr. Grizzard is quite goofy and awkward, but in a good way. He sometimes fumbles his words, but he always gets the point across. Overall a very good teacher and I enjoyed the class.

Fall of 2014 was Dr. Grizzard's first semester here, and based on the first day, I didn't think it was going to be pretty, but he did A LOT to improve and listened to what us students wanted. Lectures are pretty dry and not always the clearest content-wise, but he does well to keep your attention. I found his office hours to be helpful.

The class was really enjoyable. He definitely wants you to succeed and learn the material, and is really helpful if you take to initiative to ask for help. Tests are pretty straight forward but do the homework! It helps a lot.

I took him for 221 this past fall and he was one of my favorite professors. By far the best 221 teacher at Madison. The 5 lecture a week style with smaller settings was a great help. He is very open to questions and helping students. Only drawback is he gives group projects for math which doesnt really make sense to me

Very good teacher, made math seem fun

Forces you to understand the material. He teaches the foundation, you are required to build on it. Friendly and genuine.

Love his cat tattoo!

He was my favorite teacher this semester. He is goofy, awkward, and truly cared about each and every person's success. He knew us all by name (a lecture of over 60 people). Made calculus interesting and gave straightforward and fair tests. He would always set aside 2 points on the tests for us to draw a picture (a bunny, snowman, and badger)!!!

He is kind and respectful. Gets to know every student by name which is cool to see. Office hours are very beneficial but dont expect him to just show you how to do the problem. He will guide you along and make you think for yourself to solve the problem, which is helpful for tests. Favorite professor I had. Also had Hansen-Econ and Sibert-Chem

Grizzard started off the semester a little rough because this was his 1st semester. He really improved throughout the semester and was one of my favorite professors! He is a little awkward at times but it's kind of funny. There are 3 group projects given throughout the semester which are kind of pointless, but Grizzard himself is a good professor.

It was his first time teaching the class, and at first you could tell he struggled. His biggest downfall is he doesn't give enough examples. At Madison though he is probably the best teacher for calculus 221. He is kind and cares about student's success. If you show him you want to do well, he will help you succeed.

Grizzard is a great professor. The class is hard and it takes a little bit to adjust to his teaching style. The tests are hard, but he gives you a lot of practice problems. He is very helpful in office hours which I realllllllly suggest you go too.

Robert Grizzard was very amusing. He was awkward, but he made the class humorous while conductive to learning. His office hours were extremely useful, and it is important that you to go to them at some point. Grizzard was very friendly, his exams were fair, and pretty much everyone liked him. The group projects were sort of weird, but that's minor.

He really is an awesome guy, his lectures started off being very unhelpful but it got a lot better as the semester went on. If you want help, he will help you and he is very clear and very good at explaining things in smaller groups1 on 1.

He was a wonderful lecturer. This is one professor that you should go and talk to outside of class because it will help you tremendously.

He was new and had difficulties when he started out, but as the class went on he got better.

Professor Grizzard was great! I had Linear Algebra at 7:45am, yet it was enjoyable (although I kinda like math in the first place) and made sense, despite the hour of morning. He's helpful, good at explaining things, and makes sure you really understand the concepts he teaches.

FAVORITE PROFESSOR EVER. Prof Grizzard was awesome. He's really good in lecture about explaining things so they make sense and writing things down on the board. His office hours are super helpful, and he genuinely wants to make sure you understand the concepts. Tests are very fair. Seriously, take his class.

Great professor. He is definitely inexperienced but his unusual style of teaching makes his classes very easy and enjoyable. Plenty of problems in class means that homework becomes very easy to do. Very friendly and helps out a lot. Would definitely take his class again. Textbook is needed just for homework and it is available online too.

Profesor Grizzard was a bit of a mystery at first, especially with the way he teaches (involves students by giving problems to work on.. vs normal lecture). Yet, after the first exam I've come to realize there is a reason he makes you critically think during lecture. I did very well on the first exam, however I spent a LOT of time in office hours.

Awesome professor for math. Feels like a fresh blow of air in the monotonous styles of teaching in college. His teaching style inflicts a lot of pain on the students, but I guess that is what bring out the best out of me and helps me ace his tests(which are not tough at all if you do the homework and the class problems seriously and diligently).

I love this guy. He's hilarious although a tad awkward at times. Lecture is surprisingly not boring and understandable. Also, he has tattoo of a cat which is pretty neat.

He's a pretty great professor. At first, I was very skeptical. His teaching method may seem odd but it works. Plus, he's super awkward which makes the class slightly funny and enjoyable. He honestly wants all of his students to succeed and he's the type of professor who likes to challenge his students. Tough grader but fair

It's a lot of independent learning so be ready to teach yourself. He is always available for questions and replies to emails very quickly.

I really enjoyed his class style-- he had class every day that was a little bit of lecture and then getting actual practice by working on a worksheet. He could sometimes be a bit hard to follow when answering specific questions, but generally, I was able to understand most everything. Overall, he's a cool guy and an effective teacher.

If you didn't take calc in high school (like myself) I would highly recommend this lecture. You meet 5 days a week in a smaller class so you can ask questions. Gizzard's teaching style is frustrating at first but if you really put in the work you will truly understand the material. Learned more from this class than any other class I've taken at UW.

Grizzard's a pretty cool dude. At first his lecture style is a bit frustrating, but by the end of the class, every concept that's brought up you clearly understand. Compared with the other 221's the 5 day a week structure, allows for a more intimate setting with more help. Grizzard's class wasn't the easiest but was incredibly worthwhile.

Professor Grizzard was my favorite professor this semester and made Math 221 very enjoyable, despite the difficulty of the class. He is an interesting guy whose unorthodox teaching style made me think about math much more critically than I have before. Go to office hours often, work through problems! If given the opportunity, take this class.

Professor Grizzard was one of the most enjoyable professors I have had in my college career. His style of teaching made me really think and work for my grade, which allowed me to delve much more deeply in the subject matter. Go to his office hours often; he is so willing to help! I would definitely take a class with him again.

Gizzard really cared about his students and wanted everyone to perform well. You definitely have to put in work and do all the worksheets, but the tests are never too surprising and the previous exams really help a lot in studying. He was very easy to learn from and I highly recommend him. The final was the one exam that was very difficult for me.

Great professor

Prof. Grizzard is a great guy. He super quirky and funny, but his class is more of an independent learning style (e.g. he answers your questions with more questions to make you think). If you put in enough effort to understand WHY you're doing everything, this class will be doable.

Prof Grizzard was a true gem who sometimes accidentally gave solid life advice in math terms. "You have to balance your life" -Prof Grizzard

Grizzard is a great professor. I was initially worried by his alternative lecture style, but found it to be much more productive (at least for me) as the semester continued. Every day we either start with a short lecture and move into work time on worksheets he'll hand out or go straight to work time. Weekly homework/quizzes, manageable exams.

Good overall person. Really nice and caring if you go to office hours. The set up of the class is more like a standard high school class with more problem solving in class. Kinda nerdy (as any Doctorate in Math) but funny. Great person with a cool cat tattoo that you should look for.

Great math teacher that truly wants his students to understand the material. His office hours are super helpful and a great way to get the homework done. Class is either hum lecturing or everyone working on a worksheet. The exams weren't too hard if you understood the homework and worksheets. I learned a ton

Amazing Professor

Overall very nice professor

This guy was great. He had great office hour times and was big on teaching us through participation. We did a lot of problems in class. It was awesome. I came in to Calc. 1 not knowing much but left a master.

This professor is easy to understand and cares that students understand the theorems used to solve problems. Overall he is a comprehensive lecturer, and smart guy--if you take good notes, do the homework and pay attention you should be good.

I think Bobby was a very good professor. He has a different way of lecturing that some people might not like but he is always willing to help and answer a question

Grizz can loose his train of thought a bit during lectures which can be a bit of a downside, but I felt he did a very good job of explaining where things are derived from. There was practically no memorization in this class due to in depth explanation of the theory of the topics. I recommend using textbook and all other resources. Class is tough.

You absolutely have to attend lecture to do well, and although it seems unorganized at first, looking back at notes you realize how well Bobby teaches. He's funny and caring and gives you every opportunity to do well, even if the class is hard work. I recommend sitting in the front to hear him best and be able to read his handwriting.

Bobby is the best math professor I've had in college. He places a heavy emphasis on working on practice problems during class and he logically builds up one topic from the next. I've had him for calc 2 and linear algebra, I wish I could have him for every math class. Phenomenal professor

I've taken four math classes at UW and Grizzard is definitely the best professor I've had in the department. Teaches in a way so that topics are constantly building off the previous ones, and emphasizes understanding things conceptually and practicing the arithmetic. My only complaint is the class was somewhat disorganized and inconsistent.

After taking a different math professor on campus, I really have grown to have a strong appreciation for Bobby. He gives lots of examples, has good discussion worksheets and makes himself available. Bobby is super approachable and makes himself available to the students. He teaches through examples but gives lots of review material and practice.

Super nice

Bobby is a really nice professor. Although he does upload videos late sometimes, I could see that he's really trying. His grading criteria is very straightforward. He is also lenient. I really respect Bobby.

I'm so glad I had Bobby for calc this semester. He would post video lectures for you to take notes on, and then during the synchronous lectures would allow students to ask questions about the homework. He did post some videos late, however, but would always extend the deadline for homework if that was the case. Videos included cameos from his cat!

I loved having Bobby for Calc II! He tried hard to make online classes fun, literally had a beach themed background just for online class, posted videos for lectures to watch whenever and then during actual lecture time he would answer any questions you had. He was sometimes behind in posting but always extended deadlines. My fav prof so far! :)

Bobby was a real gem. While he wasn't always responsive outside of class, I think this can be attributed to what this semester was. Bobby clearly explained the topics covered in each unit and I felt that he adequately prepared you for each test. While the online format of this class made things more difficult, I would strongly recommend Bobby.

Seems like I had a very different experience than a lot of these reviews. Bobby is hands down the best math teacher I have ever had. I do agree that he was behind at times, however his videos were incredibly clear and I liked the fact that we could ask questions as lectures. My advice is GO TO OFFICE HOURS. IMO, take your math courses with Bobby!!

Bobby is a great professor. He's incredibly kind and friendly with his students, very clear in his lecturing, and is always accessible. He assigns HW problems that are just difficult enough to challenge you but not overly daunting, and likewise his exams can be challenging but certainly not unfair. Overall, he is an excellent professor!

Bobby is an excellent professor. He's really friendly and easily accessible. His lectures are engaging and easy to follow if you're comfortable with proofs. His homework assignments are reasonably challenging and reinforce the material covered in lectures well. His quizzes and exams are also very fair with generous grading.

Bobby was my first math professor and surely was one of the best. He was interactive and fun to have as a professor in lecture. Also, always open to new ideas and input. Glad to have taken a class with this guy.

Bobby was an interesting professor. If you took calc in high school and did well, you will be able to do well and enjoy his class, if not, do not take him. He focuses on little details a lot of the time and you will find yourself learning the material in your own time. Lectures were interesting and a really nice guy, but not the best teacher.

He was a very funny lecturer as far as math lectures go. He was clear with what he taught but did go on tangents often. Would take again.

Often, Bobby can make it difficult to understand because he can get quite scattered while teaching when he doesn't come prepared. But when he is, he's a beast who who teaches us concepts without needing to really rely on the formula and truly understand the meaning behind us making certain calculations. He is extremely helpful in his office hours.

He's a great guy and super approachable outside of class (and extremely helpful). Math 222 is an inherently difficult class, but he still does a great job teaching it. He may be a bit disorganised sometimes but he's still one of the best professors I've ever had. He's hilarious too.

Bobby is clearly knowledgeable and tries his best to convey the concepts to us in a way that we can understand. Sometimes he can be all over the place and difficult to understand, but overall not bad. He likes to derive equations and give intuition, making it easier to understand the topics.

Bobby is a great soul (loves TayTay). Lectures weren't the best but were fun! (helps w/morale in 222). His love for the subject shows in post-lecture doubts. Behind his tangent-filled, informative lectures, is a smart person who loves Math. He develops intuition to solve problems - he does 2/3 examples per lec but your understanding will be deeper.

Took 221 and 222 with him. Will say, 222 is better if youre taking him than 221, as he was more invested in 222. he always records lectures so I just watch it on my own. in lectures, he's really scattered but when watching it at 1.5 i focus a lot better. hes funny, goes through 3 examples but dis/office hrs makes up for the lectures.

He seems somewhat disorganized and can ramble. If you have a phobia of filler words during speeches, he's not your man.
