Super, super, interesting class, but at times the tests were difficult. There is a quiz on the material every two weeks, each quiz consists of a written and a multiple choice section. It is pretty easy to get an A in this quarter of the class if you do all of the work and do well on the final, but again the quizzes can be a little tricky. Due to the TA strike a lot of things were graded on completion rather than quality, so there may have been a bit of grade inflation. I would recommend this cluster for pretty much anybody. It is really interesting and Jewitt makes it fun.

My Cluster 70A and 70B professors were Petigura, Jewitt, Friscia, and Brown. This was my favorite class all three quarters. The topics of the evolution of the universe/galaxies/stars/planets/life/ecosystems were SO interesting. I would absolutely take this class again in a heartbeat. It has upended my life plan because now I am debating pursuing a career in astronomy/biology/ecology. Jewitt was an engaging lecturer during 70A, and I was stunned to find out that Jewitt is LITERALLY one of the people who discovered the Kuiper Belt. He is remarkably intelligent -- regardless of how controversial of a person he revealed himself to be in 70B with controversial statements. TAKE THIS CLASS THO!!! I'm pretty sure the department talked to him about the complaints he got. I would take this class 600 times again if I could -- I totally adored it.

this man literally cancelled the planet Pluto

Jewitt is the man! Lecture is not necessary, but I went to every single one because Jewitt is so interesting and passionate about the subject. He gives you a list of questions the class before the final, then picks about 40 of them for the actual final. It's pretty much a race who can fill out their scantron the fastest...I got a 100% on it!

You watch BBC movies in the class which star Jewitt...he's a giant in the science community. Section was also pretty fun...both TAs are always looking to help. There is a ton of extra credit offered and I ended up with an A+ in the class.

Take ESS9--you will not regret it!

I didn't find the class as interesting as others did, but the class is easy and the professor is great. There's a lot of extra credit opportunity. The midterms were tough so I was worried about my grade, but he gave us the questions to the final so I got a 100% and passed with A+. You have to go to discussions for lab but not lectures.

Previous reviewer hit it correctly. Professor is amazing, class overall is easy. The multiple choice midterms were hard, and I did get low grades on those. No worries though since there is a ton of extra credit stuff the prof. hands out. We had to go to Griffith observatory and even build a telescope among others to get extra credit. I think the extra credit stuff amounted to 20-25% of the overall grade. The final was also easy since he gives you the questions beforehand. I also got a perfect score in the final and an A+ in the class. Going to class sometimes was kinda boring though, but powerpoints were posted anyways so I didn't really miss that much, although I wouldn't recommend missing a lot of classes since the professor also talks about some stuff not really found on the powerpoints.

This professor is by far the best professor I've had at UCLA and not because he gives lots of extra credit (which he does) but because he wants his students to learn without the stress of grades. This professor is well known across the world because he has discovered so much! We watched two videos throughout this course and he was in both of them! He found an object in the asteroid belt that had an icy tail and this discovery helped prove where earth's oceans/water came from. Really cool! He also knows so much information but explains it in a way so everyone understands the information. I actually enjoy going to this class because he makes a few jokes and clearly goes through his PowerPoint slides. This class has made become so interested in astronomy and I would definitely take another class with this professor! Take this class, you won't regret and you will learn so much with the benefit of receiving a good grade!!

Professor Jewitt is a true master of the skies, despite having ruined my childhood by being the one who proved that Pluto isn't a planet by discovering the Kuiper Belt. No, seriously, he's the reason; he's discovered like a hundred moons, too.

At first, I was scared to take this course because I heard horrible things about some other instructor of ESS 9 who made this course as hard as a graduate class.

Glad this isn't the case for Jewitt. This class was probably the easiest A I've ever gotten in my life. You have the chance to get up to 30% extra credit of the ENTIRE GRADE by going to the Griffith Observatory and checking out other cool astronomical things around LA and UCLA.

The class content was very interesting and fun, too.
This is one of those classes all the super North Campus people take when they have the mathematical and science skills of an 8th grader.

All in all, I very highly recommend Professor Jewitt for a fun and easy class; he's hilarious and engaging, and almost always lets us out 15-20 minutes early... Plus, he's currently one of the most famous men in astronomy; people like Jewitt are the reason I'm so damn proud to be at UCLA.

Best professor on the planet. He is soo nice and so interesting. You will WANT to go to his class. He is amazing and a flippin genius.

A great professor. I am so glad that I have him this quarter. His homework assignments are easy and interesting. He gives out questions before the final and picks about 40 of them as final. So if you are prepared well, the only thing you need to do during the final is fill out your scamtron. I think many people did well.
