Last month I participated in a CTF event organised by the RR team in Indy through this platform, CyLab Security Academy. The challenges covered several categories and were organised in 6 levels, each level only made available if you solve at least 50% of the challenges in the previous level. While some challenges I could solve in a few minutes, others took much much longer. In fact I got stuck for days in a reverse engineering one. I ended up learning a fair bit about assembly and radare2 through The Official Radare2 Book and eventually cracked the challenge. However I ran out of time and could only complete one more challenge before the deadline. All in all, great experience. I decided to go solo instead of teaming up with someone else and managed to finish in the top 10th percentile of participants (~13th percentile of people who at least solved one challenge). Nothing like jumping into a new topic to see how many things you don't know...
