61b getting ahead?

hi, i want to get started a bit early for 61b this semester(hilfinger) because i really need to do well. i was looking at the website for fall 2021 and it seems like all homeworks/projects are not available to the public. is there a place where i can find these assignments so i can start early? if not, are there any other methods i can do to prepare? all i have been doing so far is watching hug's lectures. thanks!
