As a ps gen-ed, I took this class only having some knowledge in physics. I assumed since it was a 100 level it would be more basic than 131 or 151-not so.

do not take this class if you're looking for an easy PS gen ed. It doesn't matter if there is no lab attached to this class, do nottttt take it. exams are worth over 50% of your final grade. so it doesn't matter how well u do on the thousands of hw assignments, u do badly on the exams, u FAIL. And the cherry on top is the exams are short and HARD.

DO NOT TAKE. Signed up for Physics 100 as a gen-ed and had the most miserable semester of school because of this class.

Guy is so funny and the lectures were very interesting. HOWEVER probably the hardest class I've ever taken. The homework is once a week and 45% of your grade but the TA's grade it extremely unfair and makes it almost impossible to get a 100. The exams are 50% of your grade and they are so difficult and you never know what's it gonna be on.

Guy is a great professor. Lectures are interesting, full of demonstrations that keep you engaged along with his sense of humor. However, the exams are 20 multiple choice questions, so if you mess up a few questions, you grade suffers greatly. Would not recommend for a gen ed as it can be a struggle.

Guy is the goat. Pedagogy is super respectable and fair. Course material and lectures are engaging with genuinely useful real-world applications. If you do the work, take lecture notes, and think critically, then you'll do fine. Just make sure you're interested in the subject and good at MCQs: two 25-question MCQ exams are 50% of your grade . . .

If I could give Guy a zero I would. Lectures were mediocre at best and cringy at worst. Homeworks are worth 45% of the grade and are long, difficult and graded harshly. Two exams make up 50% of the overall grade and are trivial MC questions that are difficult to study for. The exams do not relate to the class material at all and prof isnt helpful.

Homework was outrageously hard and counted for a large percentage of the grade. $100 textbook for a gen-ed. Very math-heavy. The lectures were boring. Tests were impossible to study for and contained mostly random questions. Material that I honestly don't need to know for life.

This is by far the hardest class I have taken at umass. He requires you to just know all the math needed without teaching it. None of the homeworks make any sense and tests and impossible to study for. Do not take this class.

I swear on my life this is by far the worst class I've ever taken. The TAs are useless, I went to many sessions and my grades were still tanked. The professor although quite funny, he just expects you to know A LOT about math for an entry level course. The tests feel almost impossible, and the homework is such a joke, they grade it so horribly.

Teaches as if its not a gen ed, and expects that you have background knowledge on astronomy. Too much work for a gen ed, and be prepared to teach yourself math you have never seen. TA's grade harshly. Avoid this class.

Every great review you see for Astro 105 ignore, do not by any means take this class. Guy is a hilarious dude don't get me wrong, his lectures are quite funny, but the class itself is awful. Far too much work for a gen-ed, very confusing work he gives very little support for, and possibly the worst TAs I've ever experienced. Avoid.

Find a different class to fulfill your gen-ed. And if you need it for your major, consider switching majors. That's all.

Funny dude but the class was so hard. I took this as a gen ed, might pass. Weekly quiz online, weekly reading with mandatory comments online, and weekly homework. He puts the slides online and lectures which is great but that alone won't be helpful. No extra credit really. For exams, there's 3, he allows a piece of paper but that doesn't even help.

His test questions were extremely specific, often statistic-based questions that make it almost impossible to do well on the tests unless you have a photographic memory. Tests were a large percentage of your final grade.

I took this class as a physical science gen ed and trust me it was no worth taking. Spent more time working on homework and studying in this class then I do on classes for my major. Impossible to get 100s on quizzes and home works. As well as a $60 textbook...

Don't take this class unless your interested in Astronomy!! Very difficult impossible to get good grades unless you care about the topic. For the homework they dock points for every little thing so read carefully and answer all parts of the question.

Very difficult grader, and with all the homeworks, quizzes, and graded readings it can be a lot, however he rounds the homework grades up by 10% at the end which is helpful and the worst exam grade is worth less than the other 2. Very hard class, but probably more manageable than any other physical science gen ed

The class is very interesting, and i enjoyed it. Homework is so much more stressful than it should be and graded quite harshly, but for a physical science gened i much prefer it over regular physics or chem. The lectures are very important for both the homework and exams, and going to the ta help sessions are very helpful.

Definitely a challenging class, the homeworks are really heavy against your grade but he rounds up by 10%. Go to the TA help sessions they boost your grade. A lot of work for a gen ed wouldn't recommend if you're not interested in weather.
