Spring 2020 - astro 3 with professor petigura was amazing! I liked his lectures and the workload wasn't bad and the material was interesting but above all he was really helpful and caring throughout the entire quarter. our midterm was 24 hr and open note; our final was optional, 48 hr, open note, no harm. the exams were kinda hard though. I also liked that he recorded lectures and uploaded them on ccle. labs were fine, a bit difficult sometimes but the ta (alec) helped a lot. I wouldn't say the class is an easy a but it's also not super intense or anything. either way, astronomy is interesting as hell and I would definitely recommend :)

Fall 2025 - I thought that this class was going to be easy-- as the previous reviews say. However, I think that in recent times, they have transitioned this class from primarily online to in-person, absolutely destroying the ease of this class. I would never take this class again. I studied weeks in advance for the quizzes, staying up late every night and writing every note on our one-page cheat sheet, but the quizzes were genuinely impossible. The quizzes were ridiculously hard, 20 multiple-choice questions and three throughout the quarter, asking about a fact that the professor probably said once and wrote in size 8 font on the slides. They ended up curving at the end of the quarter since the grade average was a D, but to this day, they have not disclosed what the curve was or how it was applied. My friend who had 6% higher ended up with the same grade as me. The final wasn't that bad; they realized that everyone was doing poorly and just repeated quiz questions on the final. Overall, a horrible class; the lectures were extremely detailed, overly extensive, and boring. Might be a fun class for someone genuinely interested in the cosmos, but as a humanities major, this class was NOT an easy GE. The final paper was graded lightly, though, depending on the TA. Original grade make up: Lab assignments / participation 25% A- Writing Assignment 35% Quizzes 20%/30% Final Exam 20%/10% Total 100%

Winter 2022 - If I had a shotgun stuck up the roof of my mouth and my whole family hanging from a tall tower ready to be released so their bodies splatters across the road, I would still not take ANY class with this evil demon Petigura. This guy is responsible for the mental, psychological, and physical suffering of MILLIONS of innocent lives in this world. His lectures are inherently evil and he seeks to pollute your mind with disgusting, useless information to only screw you up on the quiz with questions you've never seen before. His goal in life, his purpose in this world, is to morally degrade students. Instead of doing other things to add value to society and make the Earth a better place, Petigura voluntarily chooses to inhumanely destroy the lives of millions of innocent children, as it brings him joy to see his students fail in life. He goes to sleep every night knowing he permanently scarred millions of students on the planet with his ridiculous lectures and quizzes. If you understand you have responsibilities to fulfill, duties to perform, and values to add to this society, DO NOT get within 10 miles of this guy, because he will pollute your minds with his corrupt, degenerate, and evil philosophy.
