I'll try to release an interesting topical problem each class. These help you keep pace with the mastery tasks.
PCP2: (little tougher) findtheflag
PCP3: (HARD) Solve the February 8th "Intro Buffer Overflow" Imaginary CTF problem (Problem files with the latest glibc and patched etc can be found HERE)
PCP4: (IMPORTANT) Mastery A and B in one: Learn To See/C
PCP5: A classic crackme crackme
PCP6: Write a crackme for your fellow students and solve one student crackme.
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: LIVE ONE! hackme running at

PCP14: Help day: Pick any PCP problem, or pwn problem from the class, that was the hardest for you when you first attempted it (it might be easier for you now). Make a "write-up" that is designed to help someone else facing that same problem. Share the write-up, make the world a little more beautiful.
