HE IS SO NICE! Always wants to help. Makes his lectures sooo clear and gives you so many ways to learn it. Has an interesting slide show everyday when you walk in. Really wants students to do well. You have to pay attention in lecture or read tho cuz there are some formulas in the material but 95% of it is easy stuff and he'll help you with the res

Makes astro WAY interesting. Some homework, challenging tests, but he gives you study guides that tell you everything to study. You must go to class to do well, but class is *actually* interesting, not a drag. He knows what he's teaching and it shows...makes it very understandable. Highly Recommended.

Professor Leonard is by far the best instructor i've ever encountered. He dedicates effort to each and every lecture and it shows, because many of his students learn the material and learn to appreciate him. I'm speaking on behalf of the many who agree with me. He's quite funny too. An amazing person, indeed!!

Dr. Leonard is amazing! He uses video clips and pictures to explain only the most pertinent and fascinating material about our universe. If you're looking to take a physical science GE, astr101 with leonard is your best bet- there isn't much reading, and despite what others say the math component of it is nothing to worry over. It's pretty easy too

Lecture is not mandatory and does not help. If you do the reading outside the class you'll do fine in the class. There's an online quiz every week,3 midterms and a final. You drop your lowest midterm and quiz grade. This class isn't too bad but the material is somewhat difficult.

Awesome class. He spoon feeds everything you need to know. Unlike other subjects, there is plenty of AST info available on the web so I only needed the web-key for online hw+tools instead of the whole book. Shame on you if you can't pay attn to an hr lecture AND ALSO not grasp his topics because it barely scratches the surface of AST, chem, & phys.

In all honesty, as an individual who is taking this class as a GE, I feel more mentally inferior than I did in the beginning of the semester. The fact that our grade in this class is determined by 3 tests honestly feels inadequate in determining a student's intellect, especially when everyone just ends up memorizing and regurgitating material.

I thought this class would be a cake walk but the tests are deceivingly difficult. Nonmandatory attendance, no textbook but there is a course reader you should buy, and EASY online quizzes weekly. Teacher is nice and very well educated/respectable but the tests will have questions that will catch you off guard when you thought you were prepared.

One of the most caring professors I've had. He wants his students to pass and understand the material. The tests are somewhat difficult, and the cumulative final is 40% of the grade which is tough. Attendance isn't mandatory but lots of his test questions are pulled from lectures. Didn't ever use the textbook but definitely but the course reader!

Dr. Leonard is a professor who is very knowledgeable and passionate about astronomy making his teaching more understandable. It was at times difficult since, despite it being a 101 class, he did expect you to know a lot of specifics on his exams. Exams oddly worded so it was hard to know how to answer at times.
