NOTE: I took this class during COVID-19 quarantine online. I don't know how different it was from a regular Astro 3 course, but I thought it was relatively easy.
-LOTS of online coursework, all answers can be found online. I usually finished within 20-30 mins
-Participation isn't necessary with lab sessions, just make sure you turn in the labs every week. One week it was just me and the TA doing my whole lab together. It like office hours and honestly great.
-Rich is a boring lecturer, but honestly all the info on the slides are crucial to beating the exams. Just go over each of the slides in depth. Know them all.

Strengths- The content of this class is so cool. I looked forward to learning about whatever the new topic was for the week, and it was even more interesting to see how each topic built on one another as the course progressed. Professor Rich is incredibly open to students asking questions and always gave us an opportunity to seek help when we needed it. I really appreciated that.
Weaknesses- Professor Rich can be somewhat of a boring lecturer. He sometimes goes off on tangents about something that he discovered that relates to what we're learning, but has no resounding significance to the course. Additionally, the Mastering Astronomy assignments are quite pointless and I don't even see most of that information on tests.

Overall, a great class and I would highly recommend it to another student who is looking for an interesting G.E. that will keep them busy with lots of information to take in. Professor Rich is passionate and I enjoyed going to his lectures to listen to him talk about the universe!

maybe it's because i'm a complete idiot but this was not an easy GE like everyone says it is. i just taught myself pretty much all the material. i could tell professor rich was super passionate about astronomy. he's always more than willing to help students in office hours, and he gives out extra credit up to 2%. despite this, he wasn't the most interesting lecturer. he goes off the slides. i could tell that a lot of students got bored, because some would just be going on their phones. a lot of people just didn't bother attending lecture.

we do our homework on this website, which we have to pay for, and you can almost always find the answers online. the lectures aren't enough to be able to do the homework. you have to read and take notes through the textbook yourself. as for the lab, it wasn't super easy, but it was doable. everyone in the class pretty much worked with the people around them, and the TA would be walking around to help.

take these factors into consideration, as well as the fact that i'm kinda a dumbass (but i did end up passing the class) overall, i would not take again

ONLINE FORMAT

Non-mandatory lectures, all posted the day of. Professor Rich was extremely helpful throughout the online process. Lateness policies on assignments were lenient. Large portions of homework graded on completeness. Labs can be worked through individually, but there are plenty of opportunities to seek help if necessary.

ASTR 3 was not an easy A for me. Granted, if I could do it again, I would have definitely attended lecture more (something that I stopped doing after a few weeks into the quarter) and kept on top of the reading schedule - I think both would have made working to get a good grade a lot less of a struggle. Regardless, the content of astronomy itself was a brand new topic to me, and I had greatly underestimated what exactly it would consist of - i.e. a lot more physics and a LOT of brand new terms and concepts than I had expected. Some of it - such as learning about black holes - was extermely interesting. Some of it was harder, denser and not quite as exciting. This was made more difficult due to the weekly homework assignments (not difficult but just somewhat time consuming) and the nearly 2 hour weekly labs which were DENSE and somewhat tricky. To anyone taking this class, also be warned that the second half of the quarter picks up quickly and the chapters go into a lot more detail than the first half of the class.

I believe the reason I walked away with an A is because I was able to self teach myself like crazy before each test - I read every chapter and would test myself like the professor recommended (I would definitely recommend watching crash course as well, to anyone taking the class, as it really helps you visualize some concepts). As someone mentioned below, the professor will often put some of the review questions on the actual exam! Do not disregard this helping hand.

Professor Rich is clearly a passionate and caring professor (and offers lots of extra credit opportunities), so if you do end up taking this class, you're in good hands! Just know you MAY have to work harder in this class to do well than what you may expect from its reputation

If you have a pulse, you will pass this class. I stopped attending lecture after week 1, but was still able to do well using the online study resources provided on mypearsonlab. If you need an easy science GE, this is the class for you. The only thing that was slightly difficult, was the random historical questions that the professor put into his midterms and finals. Overall it was a non-stressful class. Take a deep breath, it's not that deep.

I was not expecting to, but I actually really liked this class. He is not a super engaging lecturer but he just wants everyone to have fun with the material. The textbook reading is good because he is not always clear in lecture. This class actually made me really like astronomy by the end and I would recommend it.

Easy G.E with interesting subject matter, professor is enthusiastic and knowledgeable but the lectures are rather boring

The professor can be messy and unprofessional at times, but it is a challenge to dislike him. He is very passionate about both the material and the students. He wants the student to succeed and will help everyone as much as he can. The worst part of the course is that much of it is essentially reading the textbook to teach yourself and completing the online homework by Pearson. You have to grind out the online assignments, but that is the extent of the workload. The exams are clearly rushed as they are riddled with mistakes, but I believe they were fair. You have few excuses to not get an A in this class if you read the textbook and do the homework which admittedly can be a rough and tedious chunk of work.

Pretty easy GE. Rich is a pretty good and helpful professor, and lectures are interesting if you enjoy the content. There's a decent amount of online homework, but most answers are easily found online. Exams were easy as well, especially being open note.

Pretty straightforward GE. Rich is a nice guy, clearly cares about the material he's teaching. If you're taking this online, doing well on the tests is as simple as having extensive notes (all tests are open note). If they weren't open note, they'd honestly be pretty difficult, so I assume he compensates for this by making the tests easier when the class is in-person.
The labs are fairly easy, and if you struggle the TA's are very attentive and will usually give you answers.
The textbook helps with your understanding, but I stopped reading it towards the end of the course and did fine.
