He is not a very interesting person, but he does love astronomy. If you remeber each week to do the quizzes(which are easy) you will pass no problem. I missed more than half the quizzes and bombed two of the tests, and i got a C. Easy if you do the work. And its an interesting class too.

A lot of people say that Mendelsohn is the worst teacher they've ever had. He is rude to his students, but I think he's just socially clueless, not malicious. Will repeat a lot of points throughout the semester, but the exams are straightforward multiple choice (3 midterms) and he posts reliable study guides. He's generally harmless.

Lectures heavy, tough grader,old school. Professor can accidentally sound harsh or rude to students. Not one to get along with easily. Although he lectures well, his grading policy is tough. Received B for a missing assignment that was not graded properly online. Keep track of submitted homework so the same does not happen to you.

Prof. Benjamin is a great professor. He offers a lot of help if you just ask him. He is accessible, if you ever send him an email on Canvas, he would reply in maximum 30 mins. If you are struggling, dont hesitate to contact him. Be ready to read a lot. His lectures are heavy but very informative and helpful.

Don't take this guy if you are a visual learner. SUPER textbook heavy. If you don't read you won't get the quizes right. I took this online because of corona so didn't have a choice. He posts these "Lecture tutorials" which are basically worksheets, says it'll be on the tests wish he would actually go over the worksheets if it was tha important.

Terrible professor, wont grade an assignment if one page is out of order, he makes it impossible to do his class and has a lot of the work barely accessible. Do not take him whatever you do steer clear.

He sucks at explaining how his assignments should be completed. Points are not given based on the amount of the effort you put into the discussion. If you forget to respond to someone on a discussion, that is already half your points gone. He also is so specific on submitting assignments the way he wants it, and leaves no room for mistakes.

Beware! Avoid at all costs. Some profs inspire you to love to learn; Benjamin leaves you frustrated, bemused, and despondent. Has no empathy for assignments, does not care about your extenuating circumstances, will give you a Zero for one tiny "mistake" as simple as using bullet points instead of numbered bullet points. Does not explain material.

HA HA. The biggest joke. It's rather funny how uninspiring he is. Does not adequately teach anything. Very pedantic, do not ask questions because he gets very defensive and will guilt trip you for no reason. He will not answer your questions, will not email you back, will not listen to your concerns, will not help. I wish I enjoyed it--worst class.

Atrocious. Learning is inaccessible. Resources are dated. Will give you no credit for labs and assignments if one thing is out of order. I emailed him 6 times, never once did he reply. Does not care about anyone's varied accessibility to wifi/learning resources/materials. Due dates can be changed the day of without notice. Very rude and apathetic.

Participation and effort does not count for much as youre graded off a badge system which is very inconsistent and confusing. Class often leaves most students lost & bemused, and the prof- is extremely difficult to have any interaction with. Overperfection is expected. Can easily become your most frustrating class. Proceed with extreme caution.

This guy... Oh boy, where to start? Ever have a teacher that hates it when students figure out something on their own? He actively shuts down students who come to realizations in his class. For a class that is basically "stare at the stars", he expects a lot of studying and work. Only benefit: His grade scale. 80% is an A.

He was extremely rude and lacked empathy, but expected respect when it goes both ways. While I got a good grade in his class, I was belittled and made to feel like an awful student. If this was in person I would have dropped. Unsupportive and tries to guilt trip you for his miscommunications. Assignments lack thorough instructions.

Mendelsohn has a particular teaching style that takes adjusting to. Though sometimes rude, he means well. To succeed, use the textbook, attend class, and try unstuck study for handy study tools. The grading is tough but fair.

Students must combine multiple files into one PDF to submit on Canvas or you get a zero, which is time consuming and few services do this for free so he can save 2 seconds in grading. He uses materials from places like ASU (HabWorlds), so I must check multiple places for daily assignments. He bans AI, his feedback on hw is 100% AI (zeroGPT confims)

Benjamin Mendelsohn's passion for the subject he's teaching resonated with me, even though—due to a number of personal reasons at the time—I was struggling. He's old-school, but his lectures are frequently intriguing, backed by a nice sense of humor. If he didn't single me out over an issue (which is a trigger of mine), I might have stayed.

RUNNNN! Reading the course description might sound like the class is easy but it ain't specially with this professor. He doesn't teach instead he expects us to know everything. When asking for help, he doesn't tell you the answer which leaves you feeling overwhelmed because you have to figure it out yourself. He wants everything his way.

Very rude! Don't miss a class ever, you really won't be able to make up anything if you do. I had a "hybrid" format but the integration and communication for every assignment was poorly done. Any email I sent would receive a passive aggressive response.

At first, his lectures were interesting and well-paced. But later, he began assigning 8 assignments at a time, all due the following week, on top of labs and lengthy videos. This class is too much and strays too far from stars. His attitude is snarky and passive-aggressive. Most students dropped before midterms—choose another professor if you can.

Mendelsohn should be studied as a case-study on how not to teach an aviation class. His class is built on boring recorded lectures, unclear assignments, petty grading, disorganized and error filled quizzes, and condescending messages to students. He also takes forever to respond. His entire class (which he teaches as a hobby) should be scrapped.
