He has the worst hand writing. Everything he says is so confusing, mainly because he says whatever passes through his mind.

This is one of the hardest sciences to take. The lab that goes with it really does not go with the lecture. He had 3 types of tests while I took the class, T/F/? , T/F, then matching. I failed at least half my tests which are 80% but I still got a C+ because of the strange curve he calculates. The homework will save you but it will take 3 hours!

Professor Perry is the man. His class is the most reasonable science class imaginable.

Prof Perry is extremely knowledgable in Astronomy. He presents the newest and most exciting information, as well as the history of how we got there.

A good class to take if you're not a science or math major since he explains everything in plain English. I do recommend going to the TA's office hours if you don't understand the quizzes and want to do good! Really enjoyed this class even if it was just to fill the science requirement.

worst prof I've ever had. 0 empathy, I was in the ER during a test & he didn't let me retake it. He never replies to emails and if he does he copy-pastes them & then proceeds to tell u to talk to a TA bc it isn't his problem. Lectures don't make sense, very math-heavy, the quizzes have nothing to do with what u learn in class. NEVER take his class.

At first I liked John because of how passionate he was for astronomy, but over time he taught me absolutely nothing. The lectures had nothing to do with the quizzes or exams. The lectures are so confusing and make no sense. He is not accessibly outside class and leaves all the problems to the TA's. Everyone I know in this class is failing. Awful.

He is super passionate, so lectures are made interesting. The class was super easy and open book quizzes/finals, which makes it easy to get a good grade. The lab was not great online but the TAs were helpful.

I had John for 3 classes. As an astronomy minor these classes weren't the easiest as tests/quizzes do require work. Astronomy isn't supposed to be an easy topic, and being that its changing topic its complex, and people don't realize that so they dismiss the class as bad. John is an amazing prof and person. Worth taking, just put in the work.

I love how John is very passionate about the subject and its fascinating to see him go on and on about the topic within a long period of time. However sometimes his slides sometimes dont match up with what he says.. so take note of what he says and that will be your best help for the homework. TA meetings are great. Astronomy is awesome.

John is a nice guy and very passionate about his profession but the course was unnecessarily difficult. Though he is understanding enough to give generous curves and drop the lowest grades, but avoid this course if you can. Tests were also difficult to study for because the question where very random and specific.

John is so sweet but this class killed me. The class is taught in English, not math, but attempting to learn strictly physics concepts is pretty hard, and the quizzes and tests are almost entirely word problems. I honestly stopped going to class because I felt like the lectures did not prepare me at all for the quizzes.

Minored in astronomy and took basically every astronomy course offered at UVM, John is a great guy, knows what he's talking about and is very passionate. Lectures include a lot of information. Exams can be hard but he gives everything possible to pass it. Literally gives you the questions lol. GO TO TA SESSIONS AND OFFICE HOURS, best way to pass!

Took this class expecting it to be the easiest way to fulfill a science requirement. He "gives" two thirds of the exam questions before the exams, except when he decides he wants to use completely different questions. Lectures are incredibly boring and the assignments are designed to trick you and are littered with errors.

Interesting course, taught in a way anyone can understand. Listen to what he's saying rather than what's on the slides. Those who hate this course just take notes without actually listening to how he's explaining the concepts. He's a great guy too. Quizzes are more difficult, they test understanding rather than memory.

My Brother in Christ knows what he's talking about but strictly talking about physics with no math substance and heavy theoretical topics that can leave one mind boggled doesn't leave the best experience possible for students.

It's really important that you listen to how John explains the subjects instead of writing everything down on the slides. It can be difficult to absorb all the material he covers each lecture, but having a study group or a couple friends to help take notes will make your life a lot easier

John really knows what he is talking about, however he gives lectures like we understand the material as well has he does. He goes over too much in class that it is hard to follow what he is saying. If you are really struggling go the the TA help sessions, especially before a test because they will give answers on the possible test questions.

John Perry is an amazing professor. He is incredibly passionate about astronomy and loves to share his knowledge and excitement with his students. The topic itself is very dense and a little difficult to grasp but John tries his best to explain it in a way that makes sense.

John is awesome. He cares so much about astronomy and it's clear in class. He is funny and enthusiastic, only recognizable if you are engaged. Weekly hw assignments are doable and tests fine if u study. Might be f*cked now that Hazel (amazing TA) is gone, but review sessions were insanely helpful. I rcmd this course if ASTR program can stay afloat.

Perfect for non-stem majors! Lectures are really interesting, it's complex but John is a great teacher and is very helpful. There are weekly quizzes - easy A if you pay attention in class, easy B if you google it. And 3 exams that are difficult if you don't keep up, and if you don't the curve is a lifesaver! The lab was easy and fun too.

This class is difficult, but John is great guy and makes things as easy to understand as possible. He makes the lectures interesting and fun and is also super funny himself. He knows what he is talking about and is a pleasure to listen to. The tests are hard but everything is curved so don't worry about getting a bad grade.
