confusion regarding single course (repost)

, l'm taking pre-Calc as a prerequisite to get into computer science, this is my intro into WGU and I'm a little confused. The only thing on my portal is quizzes/midterm. I really thought there would be some course material to be studying or do I really have to use external sources for everything? just need some guidance plz

(post again because i just need an answer 😭 at least tell me where i can find one)

thanks!
