I have participated in NACLO for the past two years and not qualified for Invitationals. I scored roughly a 40 in 2023 and roughly 60 in 2024. However, I also did not prep for those two years. This year, I'm working through roughly 1 chapter of Vlad Neacsu's prep book every 1-2 weeks and working through all the open round problem sets. If I finish those, I hope to finish Radev's red and green books.
