Lectures are packed with info but if you find astronomy, math, geology, etc interesting then it will be a fun but semi-hard class. Lots of reading, minimal math, mostly memorization.

professor seems chill, but too too much homework. As a summer online course, it takes about at least 3 hours per day.

geller is very passionate about astronomy but you have to stay on top of the lectures and assigned reading or the concepts will be hard to understand. homework was online but easy, sections were essay questions (also easy), but some midterm/final questions were tricky and weren't covered in lecture.

He's a chill guy. He loves Astro which makes it fun to hear him talk about things like the multiverse. Hw is through Achieve which is not my favorite but its manageable although kinda annoying. For a GE though, it does take a lot of time for reading and then rereading to study.

Prof Geller was very thorough with his lectures, you should go to lecture if you want to understand the material fully, along with reading all the chapters assigned. If you're interested in this topic, its not hard to pay attention and grasp the concepts, if you're not interested, its probably going to be rlly hard. Lots of hw too, but easy.

I adored Geller's Astro 1 class. You can tell he loves teaching it. The class was thought-provoking and made me appreciate life more. If understanding the universe, stars, planets, and other celestial phenomena sounds boring to you don't take the class. His physics courses artificially lower his rating. Don't let that deter you from taking Astro 1!
