PCP7: Flag Checker
PCP8: Solve the first of the 0-hero problems at https://sec.prof.ninja/challenge/, you'll just say "got it" in the discord, maybe your pwntools script.
PCP9: Try out https://ctflearn.com/challenge/1011

PCP13: Solve ROPEmporium callme32 you can say "got it" with spoilered script or some other proof.

PCP20: RESET/SIMPLE ONE! Run either of the two scripts from class using gdb with pwndbg and after a malloc vis the heap, take a screenshot and share.
PCP21: RESET #2 Use the playground code from class and generate a leak using Use-After-Free. Use pwndbg to identify what you leaked. Extra points if it is a glibc leak.
PCP22: RESET #3 Use patchelf to link your playground to a glibc with safe-linking and one without, capture a screenshot of both types of leaks (one encrypted one unencrypted)

PCP25: CONCEPTUAL: suppose you need to get a CHUNK where you can UAF into the largebins, make a pseudo-code script to leak from the largebins rather than the unsorted bin.
