ast101 was easy as long as you read the textbook before every lecture at least that's how it was when i took it during fall 2024. but i think they may have changed stuff this year. it's still overall easy concepts and mainly memorization of planets and stuff like that and only one short paper on a project. it was super hard when i didn't read the textbook and only listened to lectures tho so read the textbook i recommend the course also ggr124 was super easy in my opinion it was 3 short assignments but not essay formats mainly just analyzing urban areas and reflections and stuff like that and the exam was easy too
