There is no longer a college forum to apply for college, you now every 3 ooc months have the opportunity to take an exam, if you get a passing grade amount other things to which you can find in the reply above, you gain the chance to enter college or go up one. There is Bacholor, Masters, and just recently introduced PHD, for the college degree levels.
There will be an announcement in the Academy discord to when the exams will be. (I believe there will be one this month I’m not sure)
