This page ONLY updates when there's a completed chapter, so it's a fair bit behind right now!
Here's where you can read the comic as it updates each week:
https://tapas.io/series/Space-School/info
https://www.webtoons.com/en/challenge/space-school/list?title_no=338321
:) I hope you'll consider checking it out there because it helps the comic a lot when it gets love on Tapas or Webtoons.
