For Level Up!, Jump Level Up!, … I’m looking for these pdfs. Especially the ones for Level Up Essential Life & Death.
The Baduktopia’s website went down some time ago.
The answer books for the first 5 volume and review 1 of Level Up! are still available from http://baduktopia.dtrinks.de/. Dunno for how long.
edit: Found the answer books for Level Up Essential Life & Death on wayback machine. 바둑토피아 Level Up . Unfortunately the links for Level Up! series’ answer books don’t work. Only Essential Life & Death.
I couldn’t find the answer books for Level Up! 6-10, R2, and Jump Level Up!.
