Dr. Alexander is really funny. Makes the class fun. It is difficult because you really do need to study, but it is worth the time. I have learned a lot.

It's a very hard class, but he's a funny teacher. Good guy.

Provides copious notes and examples, exams cover reviewed material

Great prof, very straightforward explaining things

Good class, not much real math, some very interesting topics. I didn't think the class was all that hard, but a lot of others did. He made the class fun to go to, pretty much.

Exams are very hard. You must study beyond what the book says but also know the very concepts inside and out to do well. However, he is an awesome guy, very friendly compared to other physics professors, and really down-to-earth. He's pretty funny too and lenient/flexible on a lot of stuff. I definitely recommend him.

He's an awesome teacher. His tests can be kind of hard but they aren't impossible. His lectures are amazing! He has all sorts of videos and pictures and simulations he shows you to help you understand what the lecture is about. He's a really great and really funny guy. Definitely take him if you get the chance!

Good guy, he's helpful and nice. You have the opportunity to earn up to 14% of your grade in extra credit. Pay more attention to studying the book and past exams than class notes. Attendance isn't checked, all exams are multiple choice. If you do go to class, Alexander won't put you to sleep, he's funny at times and seems to enjoy teaching.

A very good teacher. Lectures are fun and interesting and he communicates the information clearly and neatly on the projector. To do well in the class you MUST complete all the textbook readings. He offers MANY extra-credit oppotunities totaling around an extra 7-8% added to your final grade. A very easy A.

Dr. Alexander is very interesting and loves his job! It's great, because he's fun to learn from.

He is a great teacher, and keeps you awake, which is hard to find these days.

Dr Alexander is awesome. His lectures are simple and he throws in the occasional science related jokes and offers a ton of extra credit. The tests are hard but besides that the class is easy. He is a great guy and is very helpful. great class to take

Great class, pretty easy if you can pay attention and get into it.

If you've ever wanted to learn about astronomy, this is where to start. His lectures are incredibly thorough and comprehensive, I never imagined learning so much about the topics in one short semester. His exams are difficult, to say the least, but the loads of extra credit he offers more than makes up for that. I'd recommend this course to anyone.

Dr. Alexander is a great professor. You learn so much about astronomy in such a small time but his exams are difficult...However, he offers so much extra credit through the homework assignments that I literally failed one of his exams and still pulled off a B plus! hard course but easy to do well if (if that makes sense). Def. recommend this guy!

You get really into the class because he loves the topic. It is lecture so individual questions are hard to ask. The exams are EXTREMELY hard but it is such an interesting class i never have wanted to skip. He shows a lot of pictures and videos... and also shows movies in class about once a week

Guy was great to actually learn the material. Exam grades are rediculously low but makes a huge curve. Class wasn't doing well so he made one of the tests take home. Pay attention to his lecture examples cause they help a lot. Convinced me to major in PHY

Alexander's a cool dude. his class is rather hard though, especially for a 100 lvl class. his tests are very hard, but he gives homework and tons of extra credit to help you out a bit. BE SURE TO USE THE WEBSITE FROM THE BOOK HE GIVES YOU. he takes questions from there and puts them right on the test. haha i didnt realize this until it was too late

Overall, I enjoyed this class. I learned a lot of great information about astronomy and the universe thanks to him. However, your grade in his class is almost exclusively based on your reading of the BOOK. Exam questions come from there, online homework is made by the book. That's how I got an A in his class. Great movies! Lots of extra credit.

Tough prof. in this class. You have to be willing to do alot of practice problems b/c his exams are difficult. Fun guy though, class is interesting. He also curves the grades at the end from what I heard. He's tough but fair. Be ready to work hard though. Not impossible to get an A.

Very tough class. I got more out of reading the textbook than going to the lectures. Online hw can be difficult, low test averages.. the only positive in the curve that comes at the end of the semester

great guy, speaks english unlike a lot of the physics department. Good teacher, but if you can't do physics to save your life like me his all multiple choice exams can be very unforgiving.

I studied physics for 6 years and he is the best professor I have ever had. His lectures are super clear!!! Just take notes and keep it for the rest of your life! There are lots of ways to improve your grade. There are masteringphysics which is very helpful to practice the knowledge. Also there are couple of tests.

SA is a very clear and organized professor. Physics is a very difficult subject to teach and he did a fantastic job in emphasizing the basics of physics and providing structure to problem solving while providing the theory behind the subject material. Exams are challenging but do your HW and practice a lot, and you will succeed. Awesome professor!

Alexander is a great professor. He makes his objectives very clear and teaches you want he wants you to know for the tests. However, the tests are difficult due to the multiple choice questions and the Mastering Physics problems seemed impossible most of the time. Practice is key. I took this course in the summer and got a B. Very fair prof.

His material is really tough, but he offers extra credit that adds as a percentage to your grade... I had about 10% added to my final grade, got Ds on the first 2 exams, and still got an A. When I actually decided to read the book, I got a 94% on an exam... It's not a boring book and not too hard.

One of the best professors I've had. It's a tough class with a lot of work but Dr. Alexander is great. He explains everything in a way that's easy to understand and makes physics bearable.

Was a nice & funny guy, but hated him as a teacher. Never understood his lectures. Gave out super long MasteringPhysics assignments. He gives you a practice exam with an answer key, but the actual exam will only have like 5 similar questions from it, so don't think you can study that and be good for exam. Felt like he was trying to screw us over.

I can only speak for my Astronomy class, but I enjoyed this class. It was difficult for me, as someone who is not very strong in the sciences, but it wasn't impossible. Choose either lecture or textbook and you'll get at least a B. It takes some of both to get an A, but it's not impossible. Not a bad CAS-D/Miami plan course at all.

I had him for two semesters in a row. I never heard anyone complain about him as a prof and I think he is great. Take him if you have a choice. When doing masteringphysics hw (182), don't google the answers right away or you will fail exams. That stuff is hard and you need to understand it, not just to copy it. Go to his office hours or fall behind

Very clear lectures with lots of examples. Challenging homework. Moderately challenging exams.

He's really good - had a great physics class with him because he always explains the concepts in simple terms. He assumes that no one knows math, which is both helpful and unhelpful, and although I'm a math major, I was OK with it. Gives crazy homework problems, but they barely count for anything, and the tests are kinda hard. I'd say take him!

Reading quiz almost every class and the tests and God awful. Out of all of the options for professors however, Dr. Alexander is arguably the best.

Great prof. Posted amazing power points that were all super helpful. Gives crazy hard homework. Tests are hard but fair. Textbook helped me a lot, but most people in the class never opened it. Best option for intro Physics.

In class practice and homework are the most helpful. Lectures are pretty accurate but the textbook offers a different way of explaining things which is very helpful in some chapters. Tests are hard but if you do well on the homework, you should be fine on the exams.

Dr. Alexander is very invested in his studies, and he shares his excitement with his students. Astronomy and Space Physics is mainly an Astronomy course, and it's a very interesting one at that. He is very personal, and his lectures are rarely boring. I highly suggest taking his class.

Dr. Alexander was a great professor. You don't have to come to class, except when he shows a video, but he'll tell you; however, if you do go to class, he supplements his material with interesting astronomy stuff. Tests aren't common sense but if you read the textbook you'll be fine.

Alexander is funny, fast-paced, and likes to show lots of videos and simulations. I not only really enjoyed learning about astronomy and space physics, but his enthusiasm for the subject makes the class even more enjoyable. He does post his powerpoints online, but definitely attend class on movie days because you get a quiz over them every time.

Dr. Alexander is the preferable option when choosing a professor for 191 or 192. He is the head of the department, makes the exams, PowerPoints, and does the homework solutions by hand and posts them. The class is difficult, even with him, but he knows what he is talking about because he put the stuff together.

Compared to what I've heard about the other physics professors, he's the good one. The first test is the hardest, but not even bad if you've had high school physics. You have reading and problems every night for homework and about half the time you have a one-problem quiz the next class that matches the homework. Go to at least a few SI sessions.

GREAT PROF. PHY 191 is incredibly hard, even for PHY majors. He makes the class as easy as possible. Exams are INCREDIBLY HARD, but they are the same for all profs. Averages are about 60 across the board. YOU MUST DO THE HW OR YOU WILL NOT PASS. With all of that said, there is a huge curve at the end, about 15%... If you have a choice, take him!!!

A really really nice guy. He is a great teacher and prepares you very well for exams and homework quizzes. He is also just super chill and wants everyone to do well. If you miss class, he is cool with it and he will help you get back on track. Just be respectful and you'll get at least a C.

Love the class. Its very interesting. Dr. Alexander is great. However, the exams so heavily weigh in your grade. Also, a lot of the exams include content not mentioned in lecture, rather just in the book. He shows lots of cool films though.

He's a great guy but the lectures are heavy. Sometimes you watch cool videos but the exams are tough. I worked my butt off for the grade I received.

Dr. Alexander is truly an interesting and funny professor and even if you don't know much about physics or astronomy to start with, this class is easy to understand as long as you read the textbook and watch the lectures.

This class was kind of fun, actually. Dr. Alexander is a great guy and professor, and he always tried to make lectures entertaining. My favorite thing about the class was having homework questions that you answered while you were watching his lecture videos, where he would often tell you the answers.

Super nice professor and makes lectures interesting. Classes are kind of hard and he grades tough, but if you study and pay attention you'll be fine.

Professor Alexander is an amazing professor, I would definitely recommend him for anyone looking to take a physics class for a Miami plan credit. There are lots of opportunities for extra credit and the topics are super interesting. Lectures are a large part of the class, so always attend, but otherwise. it is a super fun class.

There's a homework assignment after almost every class, but if you copy&paste the questions into google, Quizlets come up with the answers. He has an online platform that makes you answer questions during class as a way of taking attendance, but if you text a friend for the code, you can participate anywhere. Just study hard and KNOW the material

Dr. Alexander is a very funny guy and tries to make his lectures interesting. You're only graded on 3 exams, but he drops the lowest. The final is a little tough but fine. He's very lecture heavy and goes over a lot but he makes up for it with giving you free points with learning catalytics. A tougher class but fun.

He is funny and knows his stuff. The only caveat is that his class is at 8 in the morning. If you're a morning person, definitely take him!

Pretty nice guy. Lectures can be boring but will ask participation questions during class, so no way out of buying the online textbook or really skipping class without a friend. Average on exams were quite low and he barely curves at the end of the semester but gives extra credit that is a FULL POINT OR MORE EACH so going to most is a necessity.

I LOVED this course. My grade was not exceptional, but that is my own fault. Exams matter A LOT in this class, and take advantage of every extra credit opportunity. Lots of reading and heavy lectures, so be ready to take notes. Dr. Alexander was a wonderful professor and a very caring and funny person. Not an easy class, but would 100% recommend.

The class is good, but it's a difficult class.

A good professor! Got a better grade than I expected and he was very kind.

Great guy! Got a better grade than expected. Can get boring though.

He is so passionate about his work and it really makes you care about the class. He shows lots of movies and animations during lectures. His tests are not super easy but DO THE CONTENT QUIZES in mastering astronomy, all of the test questions come from there. He is a cute old guy who loves his job.

Interesting teacher, very funny/engaging but there were only 5 grades total and the course content is tough if you did not take AP physics

Stephen is one of my favorite professors! He is so funny, cares about students, and you can tell he truly loves what he is teaching. As long as you go to class and listen you should be fine! He does offer some extra credit and there was only one group project. I really enjoyed this class and would look to take his classes in the future.

Never had any issues with him, he was very understanding. He always made his lectures interesting! the tests can be a little difficult.

Reading is one of the biggest things that I would suggest for this course even if you don't read in depth a ton. Just having an idea of the topics before you head in is a game changer. Dr. Alexander has been my favorite professor by far. PHY181 is rough either way but he is always light-hearted and likes to have fun in lectures when he can

A good guy who teaches loads of students, so if you want help you'll have to go to office hours. Did poorly on most exams but ended with a C after lots of hard work and studying. Every section will be like this though since they use the same material, but Alexander is a clear, concise, and funny guy.

The exams are entirely mastering astronomy and have little to do with the actual lecture content some of the time, but overall I enjoyed this class. The lectures are engaging and the course work was not nearly as hard as I had expected. He's great at answering questions.

Hard class subject but I chose him for the second time after 181 and would take a class taught by him again. Attendance definitely matters but he also gives a lot of resources to learn out side of class. He's chill, would recommend (but heard beers is also very good).

Really great guy, lots of jokes in class and lighthearted. The class is difficult and based upon at least 3-5 hours of homework or studying a week. Three exams and lowest gets dropped. Participate in class, do the homework, and get help if needed, and you'll pass.

He is one of the best for physics for sure. I've heard good about Beer but after taking Alexander for both semesters I can't say that I can complain too much. I love when he has fun in class because it can make the 2 hour lectures go by at least a little bit quicker

Physics 2 is hard no matter the teacher. Come to class even if your tired to get participation points. You can easily end the semester with over 100% in the participation/homework category because there are lots of extra credit opportunities. Try to study off previous exams- they don't change much semester to semester.

He is genuinely so nice and Phy111 is actually really easy if you just practice the problems in the text book. My only warning is that you can't just listen and take notes in class you definitely need to be working in the text book and paying attention to the movies.
