Not to make this bigger than what it is lol, but I have to think everyone who walks across the zodiac just does so to be a contrarian "see everyone, look at me, I don't believe in the curse, I'm a loser and have no friends". Of course no one really believes you'll fail your next exam, you just do it because traditions are fun.
You're allowed to walk on it once after you've taken your last final but other than that if you step on the zodiac you're not cool. I feel like traditions are fading at ISU (veishea etc.), keep them.
On that note it's WAY past due for the return of veishea.
End rant.
