Help a struggling engineering student out??

I have a couple questions lol I’m lost as all hell

1. I need to take Mat266 (or just Calc II) online over the summer at a Community College but I can’t find the equivalent and I called SCC and they couldn’t give me a definitive answer. Does anyone know the CC equivalent? I think it’s Mat230 but a friend of mine thinks it isn’t

2. I’m struggling ALOT in CSE100. Does anyone know of any good online prep material or tutoring on campus for it? No shade but every time I ask a TA for help, they just kinda do it for me without explaining what or why they did and it’s really nice of them but not very helpful and I don’t want to be pushy

3. Any good (secluded) study spots on campus? I hate to be that person but Hayden and Noble can get so crowded sometimes it’s a nightmare

Thank you!!
