Really energetic, cares about his students. A joke every morning. Take him if you want to enjoy physics.

good teacher, likes his electrical stuff. i didnt put much effort in so i got carried by the t-score. put the effort in and im sure youll get an A

this professor is energenic and fun, however,if you sleep in the class he will wake you up or he will throw something to you. exams are really hard but if you study, it will be okay. good teaching, hard test, every week homework, and dont miss the class

Very energetic. Loves his corny jokes. Lectures are easy, checkpoints almost every week to boost grade. All conceptual tests. Hard homework, but will give a partial completion grade.

He's really enthusiastic about what he teaches and he loves coming to teach. his attitude will rub off on you. His tests are fair, some questions come straight from notes. I used to suck at physics, but now its one of my favorite classes

very energetic teacher who will make you laugh in class. Tests are more on the hard side, and require a lot of studying. He answers every single email you send him, something not done by too many teachers.

I dunno. I never read the book and attended class regularly. I thought the class was pretty easy and survived with a B. I never really fretted anything. Final was just previous exam questions. Not taking again for PHY 2 because he thinks he may eliminate T-curve.

Great teacher. Actually teaches. Sometimes counts attendance. Assigns online hw but is easy with grading. Exams are made of problems from hw or class examples. Does NOT curve exam grades but will replace lowest grade with final exam grade.

He makes the class passable, but you gotta work for it. Dropped Jiangs class then took his, found it alot better. He's pretty informative.

horrible teacher, I was a freshman and thought physics 1 was the hardest class ever. Scared the hell out of me, almost changed my major but I am a junior right now in ENG no thanks to him, his HW is hard as hell, no one gets a 100 on it, tests are hard as hell, and you have to read the book contrary to what he says otherwise u will get a low grade

he's a good teacher, but isn't direct about what the exams will be like. the online homework he uses SUCKS really bad. if you can get through that HW you will definitely do ok on the tests. 3 exams, 1 final. i got an 89 on the first test, 40 on the second and somewhere in the 90s on the third and still got an a in the class thanks to the bell curve

Cool teacher. Homework is helpful to the tests, but not easy. The class is graded based on test grades, and the tests are graded relative to the class average.

This guy loves to teach! He's a little quirky/corny, but really nice. He understands the learning process better than any other professor I've ever had. HIGHLY recommended if you're interested in learning physics. I wouldn't call his class an easy A, but not too difficult either.

Professor Criss is truly a great teacher. He completely understands the learning process and does everything in his power to help you succeed; although his class is NOT an easy A. He assigns tough homework, but hw problems and exams come mainly from lecture notes. Study hard and go to office hours and an A is not hard.

Dr. Criss is the best! Hes exremely helpful IF he recognizes you so go to the class. He doesnt teach from the book-has his own methods, I had him for PhysicsI too and I have still never touched the book. Tests are pretty hard but he makes them that way because of the Tscore. The homework stinks but really prepares you for tests. Highly recommended!

Criss really likes to teach and it shows. I had him for physics 1 and 2 (with calc). He does lots of demos in class/videos and isn't just about notes. The homework system changed so it isn't graded as hard as before. Don't buy the book, you won't need it! Sit toward the front and ask questions (he likes that). Great class!

Dr. Criss is the man. His classes are never boring due to his engaging teaching style. He loves physics and will do his best to make sure you walk out of class loving it as well. My experiences with him are all positive, he is extremely helpful. His exams aren't the easiest, but if you study, you will do well.

There were many mornings where I couldn't stand him, but he taught the subject well. He managed to get the class engaged in learning most days and he has a WONDERFUL habit of dropping the exact wording for test questions in class. Don't miss class and there is no reason not to earn an A. Well, for energy and humanity that is.

Excellent teacher, esp. considering 150+ stud. and an auditorium. He keeps most students engaged. Homework is challenging; if it were too easy, & you got all the answers right the first time without referencing class notes or text, how would you know what you didn't know? How would you know you had mastered the material?

Awesome teacher. Probably the best physics teacher I've ever had. he really explains the concepts well, and makes class enjoyable. homework is sometimes challenging, but that's physics.

Great teacher. He challenges you, makes you think and can be quite hard. Still one of the best teachers ive had in this school.

Professor Criss is a very nice man and will never deny anyone help. still, his examples in class were quite simple when the homework requires a complex understanding of the concepts. physics is not easy eitherway.

Dr. Criss is a great professor. He makes the class interesting by showing youtube clips of the concepts we're learning. He explains the topics thoroughly by covering conceptual questions and calculation questions. Tests are hard, but the goal is to try as many right as you can and not necessarily all of them. Definitely recommend him.

Good guy, funny, keeps the class reasonably entertained. He does have a weird approach to problem solving. It's not a bad thing, but it's more theoretical than I'm used to. (he majored in Physics, my previous instructors were engineers.)Overall, good guy. Take him.

Dr. Criss is very funny. He likes to show cartoons at the beginning of class. His examples are always easy, while the homework is not. The exams are very difficult but are based on a T-score.

Criss is a good lecturer with his eye on teaching as opposed to research. He talks a good game but individual attention can suffer due to class size. He also tended to have some favorites in class. When asked to go over some questions in more detail he would ask one of these favorites if they understood and then decline to explain if they said yes.

Dr. Criss does not require the textbook; he encourages students to build a professional library with texts of their choosing. The material is fairly simple with the right perspective. "Randy" is very enthusiastic, entertaining, and caring. He could use more demos and analogies, but as-is, he is one of USF's better professors!

Dr. Criss is the best professor I have ever had at USF. He is clear and easy to understand, and he tries his best to make students interested and engaged in learning. Take him, you will not only learn, but you will understand physics.

Dr Criss is a great teacher! He believes in teaching you the concepts and his exams are 50% 'conceptual' no computing required!He teaches you the ideas and assigns homework that will work you hard and force you to learn anything you did not entirely get in class,if you dont go to class you may miss some of the concept questions and do your own hw!

I wish USF had more professors like him who actually care and want you to learn. Easy homework, very easy tests, and he will explain anything you don't understand as much as he can, whether it's during office hours or after class.

Great teacher. HW is hard but he will help with them. Tests are easy but tricky. A little bit of studying and you should receive an A on all his exams

Tests are crazy hard, but T-scored so it works out! homework is tough too, but if you go to class and understand the homework you will be fine. Its an interesting class!

Loved his class! He's very energetic and personable. He makes everything very easy to understand and only teaches things that you need to know and doesn't confuse you with any extra stuff. Definitely taking him for Physics 2 next semester!

excellent teacher. incorporates textbook rarely but lectures are exciting and personable. highly recommended.

He's a great professor and now I actually understand physics! Doesn't use the book. For exams just study by using the conceptual and objective questions and you will pass. Only problem is that it is T-Scored, so most people get B's. However, your grade is always higher than it would've been. Take him if you will go to class and do all the homework!

Criss is a decent professor. He's passionate about the subject and cares about his students. The way he teaches is a little hard. He isn't the best at explaining things and only teaches the hard way, so there's not point in attending. But the physics department has enough resources so you can still learn. With HW and T-score it's easy to pass.

Criss is a very knowledgeable teacher. I really think he does the best with the information to make it easy for us as students. You don't need the book. He responds to emails quickly and is very helpful. The material can be difficult. Go to class, not for the written material, but for the concepts and test information.

He is a great professor. I have no complaints about him, but the textbook is a whole lot of frustration and time spent scratching my head to no avail. Despite not having a useful text book, I was able to learn the material and get an A by attending his lectures. P.S. - There is hardly any calculus needed.

He's a nice guy and nice teacher. His exams weren't easy but were fair in my opinions. Attempts to keep class interesting and gets you to pay attention. Responds to emails quick and willing to help you out if you don't understand something. Take him, he goes nice and slow and won't move on if you don't get it.

He is a VERY smart &good professor. He wants the best for each student but to be an engineer you will not be spoon fed in this class. I've had him for both Physics I (B+) and II (B). If you want to know the material,take him and study your heart off. If you want the easy way out take Zhou. There is no curve except for in the hw. I'd take him again.

Loved him, so nice! He barely uses the book with the exception of extra practice problems (do those if you want to fully grasp the material and practice for the exam) he doesn't test on the material from the book, and you must attend lecture to fully grasp concepts (he tests on those!). I would take him again I actually don't hate physics bc of him

I took Energy and Humanity with Dr. Criss at USF in the fall of 2013. It's half online and half in person. You must go to his lectures (which only last an hour barely) to complete quizzes. He is an awesome, easy professor. Allows you to use your own notes on his quizzes that you hand write from material he provides online. You do not use the book.

This guy really knows how to teach. He's enthusiastic and repeats so everything is drilled into your head. You still have to study ALOT, but the guy is probably the nicest physics teachers you'll ever meet.

Dr. Criss is the best professor I've ever had. He knows what he's talking about, he speaks VERY clearly and teaches very well, teaching in a manner that is understandable due to the fact that he had trouble in college with his professor's limited teaching abilities. If you have a problem with Criss, then you probably are skipping class.

Dr. Criss is a really great and enthusiastic, university level professor. YOU WILL HAVE TO APPLY YOURSELF AND DO HOMEWORK, but if you're taking this class then you should know that already. He teaches process not formulas which is very diffferent from high school physics but I enjoyed that. I will not take physics 2 without him!

By far one of my favorite professors at USF! Corny jokes, exciting, explains material well. He is awesome. I love going to this class because of how fun he is. He simplifies the equations and makes it easy. Had to retake after last semester with another prof and he has taught everything a million times better. TAKE HIM!

Dr.Criss is probably the most enthusiastic professor i've ever had. He is so passionate and knowledgeable about physics, that it shows through his lectures and makes the class enjoyable. Tough class, but he is very good at explaining the concepts in a easy to understand way. Hands down the best professor to take for this class.

To start with, I took this class online. Quizzes are based on readings and homework is more about applying what was read, you can use book for both if needed. Although I did not have much contact with Mr. Criss, he seemed like he would be a very nice teacher in person. Overall, easy class as long as you read and understand the concepts.

Dr. Criss is a very dynamic speaker! The major issue with his class is that he teaches concepts in class, but he does not do problems. If you want to pass this class, do all of the problems that he recommends. If you have time, spend time learning how to do the masterphysics questions (but those are much harder than exams). Highly recommend him! :)

Dr. Criss is the bomb compared to anybody else in the physics department! He always helps if you ask. His classes are easy if you sit up towards the front and pay attention, unfortunately it appears as though the simple majority of students don't even come to the lecture. Oh well, easier curve for me!

Dr. Criss rocks!! Just a warning that he'll teach differently from the textbook, but he does show us how to do various problem. HW is more difficult compared to the exams. All exams are based on a t-score curve, so you'll be able to get a good grade on the exams if you do well initially. Would take him again for Physics II

Great lecturer, gives cool demonstrations and is clearly excited about physics. The online HW is really hard, harder than tests and the tests aren't easy so you definitely have to work for a good grade.

Dr. Criss does have hard exams, but he has 5-6 office hours per week, answers all your questions, and is explicit in class about what is and is not on the exam. Homework is intentionally harder than exam. Dr. Criss comes into class excited to present material and talks about concepts instead of formulas. Would gladly take physics 1 and 2 again.

Dr. Criss is the man! He cares so much for his students. He is very down to earth. If you ever have problems with the homework, he's not too big to sit down and set you up on tricky problems. I ended with a B+ in the class, but I feel that I understand physics so much better and have a strong foundation for further study.

I took him for PHY2048 and PHY2049. He taught physics the way it should be, not just through memorizing formulas. His tests were difficult and the homework took a while to complete, but the tests are curved. It's not too difficult to get a B.

What a lot of people seem to bash Criss about on here is simply the structure of the class itself, which Criss has little control over. All Physics 2 courses have the T-score system, all have a cumulative final (if Fall or Spring), and all have mandatory 10% homework. The tests are hard, study. The guy explains material thoroughly and is passionate

Honestly one of the greatest professors I have ever taken. In his lectures, he will explain things in the easiest way he can, plus he repeats himself constantly, just to make sure we get the main points. He doesn't use powerpoints, he teaches straight from the heart. But he gives tough problems so be prepared to work.

He is funny but at the same time he can be mean. I personally do not like him. In class physics seems to be pretty straight forward but tests are tough. He doesnt teach from the book so you dont really know whats going on if you dont go to class. You need to study a lot by your own to understand. AVOID HIM

This class material can be very confusing, I know I have always struggled in physics. But Criss teaches in a way anyone can understand, he is very good at teaching physics. Test are curved based on a T-score. So if you do average you'll basically get a B depending on the class and test. Homework is only a few problems a week.

Easily the best Physics professor on campus. His lectures keep you engaged and he is very knowledgeable. His approach is different from the textbook, but having the textbook helps. Homework every week, some extra credit opportunities, and 3 tests and a final. Tests curved on t-score. Not the easiest material but he definitely makes it easier.

Are the tests hard? Yes. Is the material hard? Yes. But you aren't going to find a better Physics teacher at USF so you better suck it up. Some people grasp the concepts better than others so if you aren't one of them, start studying ASAP. Not a lot of homework so give yourself plenty of time to study before the tests - they aren't easy.

The tests at first are hard, but when you see the solutions he posts after it's very basic. I suggest doing the practice problems from mastering because it is very similar to the actual exam and attend class!

Took Dr. Criss for 2049. He makes it very clear how he will teach the class, which is based on the material he covers in class and not on everything in the book. The test were fair, there are 3 and a final and all are t-score If you went to classes, do the one masteringphysics assignment per week and the additional problems posted it will go well.

Dr. Criss responds to emails quickly with clear, concise responses. I enjoyed his class and will take him again if given the option. Although, I took his online class, I selected "mandatory" for attendance because if you don't participate in the discussions within the allocated time, you receive no credit for them.

Physics is a hard subject in general, but Dr. Criss does his best to help his students understand the material. You can really tell how passionate he is about the subject; he gets super excited during lectures, which made me more excited about physics. He tells you exactly what to expect on the test. I wish I could take more classes with him!

Dr. Criss is an energetic teacher and keeps things interesting. He goes fast in class but all of his notes are uploaded to Canvas. He simplifies physics with a more process-based approach to solving problems. Tests are hard but grades on a curve with lowest test worth less. He drops lowest 3 homework and offers some extra credit. Would take again.

I never really went to class and could have gotten a better grade than I did. He is a good professor that cares about the success of his students and is almost always accessible. Sometimes he makes things more confusing than they need to be and throws random problems that have not been covered in class on the test, but he does curve all the tests.

Criss is a great professor. I had to withdraw from physics once before and was ready to change majors. I got an A. He teaches physics for people who don't get physics and stresses problem solving over memorization. Text is just for homework. Tests are 100% based on the lectures. Expect tricky questions on the tests and learn concepts over math.

The exams are tough but as long as you attend class and you are actually engaged you should do fine. One or two homework questions after each class. Great lecturing style and always stops to make sure everyone is keeping up and to drop a joke or two.

Doctor Criss provided a great introduction to physics; as an individual who has never taken a physics course before, I found that his lectures were informative and accessible. That being said, if you miss a lecture, you have a lot of work to catch up on. He creates tests directly on his lecture material, so best stay attention.

I took Dr. Criss for Physics I and will be taking Physics II with him in the spring! I found him to be a great professor. He focuses on enforcing a "process based approach" to physics which can be confusing for some, but i found it helpful. His exams are tough & but each is curved with a t-score grading scale which helps a lot.

Not for everyone, but he knows his stuff. Moves at a rapid pace, so it's easy to get behind in the material. Attending lectures is paramount for the exams. Tests lean heavily on the concepts discussed in class and very little on the homework. Hard to get an A, but an easy B if you do the work. Don't mess around in class, he hates it.

He teaches at a fast pace but mainly because there's just a lot of material to cover. Almost your entire grade is based off of exam performance but there's a generous curve (lowest you can get is a 50%). Exams aren't based off of the homework, but he tells you what you need to know for them IN CLASS. He's a great guy and just wants you to do well.

If you put in the work in his class, it's most likely that you will get a good grade. He has some pretty hard exams, but I think if you do the homework and practice problems you will be good to go most of the time. Biggest problem is he cuts some details around the last few lessons. tldr; good at teaching but has some pretty hard exams.

I took this course online with him. Wasnt bad, but it was online, so I never had him actually teach me. I recommend the online class. Only 1 homework and 1 quiz due per week. Take some time, but not horrible. Quizzes are timed, but homeworks are not. Tbh quizzes are easier than homework. Dont do the work, you dont pass. But its really not bad

I took his summer physics class. I would say that as long as you sit up front and actually attend the lectures and are engaged in the material the class is really engaging and useful. His process for teaching physics I found a lot more effective than a previous physics class that I took.

People on here claiming that his "tests are impossible" clearly don't make an effort. They are essentially a copy paste of the practice exams. Dr. Criss is an absolutely fantastic lecturer, and even as someone who hates physics, I LOVED his class!

By far one of the best professors I've had. All of the test are curved so if you do better than the majority of the class you'll end up with an A or B. Tests aren't too hard if you study for them.

Great professor. I loved the lectures. A lot of exam questions are out of the practice exam. Every exam grade is curved.

Funny guy and explains physics as it should be explained, as a process rather than searching for a formula to solve your problem. He has big curves on his exams and the lowest of the 3 normal exam grades count only as 10% of your grade, and the other 2 normal exams as 25%.

Im a biology major so Im awful at physics no matter what professor I have. I love Dr. Criss for many reasons, though. Physics is not easy, especially to try to teach in only a semester. He considers how well students understand concepts, is helpful answering questions in the canvas discussion forum, and his tests are fair if you study correctly.

His tests are very difficult. Homework, lectures, and exams don't really correlate. He's a really cool dude and his lectures make sense and are interesting to listen to and follow. Even though the lectures are good they may or may not help you for homework/exams.

He is a really good professor; clearly explains his methods of teaching and the reason for doing it. He tries to make the lectures interesting and takes his time to see if we understand. He also posts class notes as a visual aid. If you take the time to know how to do the homework, exams won't be hard. I recommend taking the problem solving class.

I recommend taking this problem solving class with the lecture. It certainly helps to understand the material and homework better. We are assigned to a different 3 person group each week to work problems together. He and a TA will help and answer questions. He often assigns problems that are similar to the exam and homework problems. 1 credit class

Best teacher I ever had in term of lecturing. However, test is HARD. To do well in the test, you have to understand every aspect of the homework. It's risky if you are the person who want to preserve your 4.0 GPA, but otherwise, awesome experience

He genuinely cares about physics and student success. He gives clear feedback and is always willing to help if you ask him in person (or during these times through canvas). His exams pre quarantine aren't too hard if you follow his "process" that he explains in lectures. This is not an easy A class at all but you will get a better understanding.

I took him for Physics 1 and 2. I had an extenuating life circumstance in physics 1 that kept me from taking the final exam until a month later. He worked with me, probably more than he should have, to help make sure I was able to finish the class. His exams are challenging, but he gives plenty of practice problems to prepare you for them.

He's got everything beautifully laid out for us. He is very clear and extensive about assignments throughout the week.

Love Dr. Criss! Took him online during covid and in person. So much better in person. Really funny and likes to have fun. Study his notes from the lectures and youll do fine. He makes it easy to learn physics and is almost always available outside of class. One of my favorite profs at USF- looking forward to the next class with him!

Dont take him online! Much better in person. Tests are from homework and lecture problems. Goes kinda fast but gets the job done. Funny guy!

I took PHY 2048 with him online and it was terrible. There was no real lecture for his online class during Spring 2021. Luckily, PHY 2049 was in-person, and I feel like I'm not as bad at Physics as I thought. He's very funny in class, and he lets us ask a lot questions during his in-person sessions as well. Overall, I think he's a great professor.

Criss is a good teacher. I hear a lot of opinions about his class and still decided to take it. He is a good teacher. Tests are hard.

Its physics. Its hard. No doubting that. But once you get past that, you see how great of a professor Criss is. He truly does care about his students, and although he may not be able to get every concept across, he is truly spending his life trying to. In lectures, he takes breaks for questions and writes emojis into his notes. Heavy dad joke vibes

He gave really tough homework and exams. What I did before exams is that I went through all his lecture notes, the hw, and the study area on Mastering. Those resources are super helpful. He curves all exams and quizzes. Overall, he's a great lecturer. I like his style and his humor.

Dr. Criss does a really good job explaining some difficult concepts. He can be irritable sometimes, but will always answer questions anyway. Homework is 20% of the grade and the rest is the four exams. There is no extra credit. He curves every exam so that the class average is a C. Exams are all multiple choice and usually easier than the homework.

One of my favorite professors he makes physics easy to understand. however, I would not take him online I heard he is one of the worst online teachers.

I don't understand why Dr. Criss has such low reviews, he's a great guy and definitely wants you to succeed However, you HAVE to put in the work if you want to do good Exams are LITERALLY homework questions He sends an announcement out before the exams that include a breakdown of what topics will be covered Homework is a big part of the final grade

Criss is extremely passionate about physics however he has a very polarizing teaching style which may or may not result in studying from outside sources if you don't get it. His grading scale is ONLY 3 exams and homework, but he curves exams heavily. He is also extremely strict about exam policies and WILL kick you out if you don't follow them

Dr. Criss is very passionate about teaching, and will always answer questions and explain it fully until you understand. Lots of homework but small % of grade, other than that 3 tests. Missing lectures will hurt you, he moves very fast so ask question as soon as you have them. If you do the hw, pay attention and ask questions youll pass the tests.

You either love or you hate Dr. Criss. If you are obsessed with a perfect GPA and getting straight A's, you will hate his class. If you only care about passing and are more interested in fun lectures, you will enjoy his class. Tests are all extremely hard, but all curved to average a C. It's damn hard to get an 'A', but it's much harder to fail.

Going to class and doing the homework are a must. He had a lot of energy during his lectures and well organized notes. He teaches strictly from a physicist perspective and does'nt entertain questions about other methods during class. Sets clear expectations for tests but they're still difficult. The curves are generous but don't rely on it.

Criss is a good guy. You will only do good if you put the work in. This is not a class that you want to skip its lecture or start its hw the day its due. Hes a tough grader but, I think that just prepares ourselves for are future classes. Generous curves if you do bad. Got two D on the first exam and a B in the final and got a B in the class.

I honestly like his teaching style, but the thing is, you have to follow every thing he says as if your life depended on it. You need to show up, take notes, and pay attention the ENTIRE time. Life is easy when you do these things, but if you get behind it's next to impossible to catch up again. Tests are very difficult, but the curve helps a lot.

I did not show up to class but managed to end up with B. However, I feel it's very difficult to end up with an A in this class. do problems in mastering to help with tests.

Its hard to put Criss in a category rating. He is a great lecturer and clearly knows what hes doing, but his condescending and harsh nature + the rigor of the exams makes his class a very difficult experience to live through. While i dont think hes the worst professor in the world, this class will involve a large amount of your time.

Do you want an easy A? This class isn't for you, but if you actually pay attention to his lectures(which are good if not great) and honestly attempt the homework, then it will be a great class. Extremely easy to access outside of class for help as he responds within minutes. Take him if you need to understand the material well.

very good professor, has good lectures. exams are hard but fair, and the curve is very generous. compared to prior physics courses in high school, i retained a lot more knowledge in this course than others.

The content is very difficult and hence his exams are difficult as well. The class average was always around 50% correct responses (eg: 10/20 questions correct), which he curves to a 75. The curve will save you. 2nd exam is the hardest. Finals was easier than 2nd. Rarely attended his lectures, so can't comment on his teaching. HW is due each week.

Genuinely tries and succeeds

A GOOD PHYSICS PROFESSOR? This professor is a role model for being there for his students. I can't even begin to explain how helpful he is, how devoted his is, and how much work he's done to help his students in any way he can. Physics is hard, and I respect his efforts greatly. Go to this guy if you wanna learn.

He is such a good professor and he makes sure that you understand the information that he teaches. He's funny and open to questions. You can tell that he knows and loves physics and is really passionate about teaching it. Definitely taking him for 2049! The tests are kind of hard but you just have to study and there is a curve.

very good lecturer. genuinely cares about his students learning. he has very cool lab demonstrations in class sometimes, and can explain very well difficult physics concepts. i took him for phy 2048 and 2049, so definitely one of my favorite professors if not my favorite at usf.

Textbook is required, however Dr. Criss does not teach directly from it. Lectures are great, though are different from other professors. No + or - grades on final grades. Tests are always curved to make the class avg 75%. Homework is done through Pearson, but allows for multiple attempts (question based). MC tests. Great prof would take again.

Criss has a very different teaching style from other professors. He focuses only on the theory of topics, leaving the applications and problem-solving to you. I found reading the textbook and attempting homework problems before lectures was very helpful. Exam questions are much easier than the homework, and exams are curved generously.

He truly knows what he teaches, and is passionate about it. You can get a good crack at some of his jokes and he likes to do small physical experiments on class that help your understanding. His exams aren't hard, but the questions were too long, especially in the final, it's almost impossible to get 100% on it. And he's NOT rude, btw.

I personally think Dr. Criss is a very caring and kind professor. His class is very difficult, but he is overly willing to help you and seems like he wants his students to succeed not just in his class, but past it. You will have to put in work to do well. Physics is not usually my thing but Dr. Criss actually made it pretty interesting often.

In my opinion, lectures can be interesting; his tests are a bit harder, but if you study correctly, you'll do well.

His lectures are great. I try to attend most even if they're not mandatory. His explanation can be tough to understand at first, but ultimately, he just doesn't want students for fall into the plug and chug pipeline. Do your homework and practice problems. The exams are tricky not hard, you have been given everything you need to solve them.

Great lectures, fun experiments in class. The materials are calculus-based but not really tough. He will take time to explain things in-depth which is a bit confusing, but he won't make you do crazy integrals or anything. Tests aren't hard, formula sheets allowed.

IMO Criss gets too much of a bad rap sometimes. Yes, his exams are hard, but it's very doable if you put in the time to study. He explains the math part of Physics well, and has cool demonstrations in class. Attend lectures, take notes on how questions are solved, do the HW, and study well before an exam. You will get rewarded for your effort.
