The Academy is divided into four faculties. Three of them are available to all Academy students, according to their skills. The Secret Faculty is for elite members with +600 points. You can join the Academy by filling in the and passing the entrance exam.
You can objectively decide yourself which faculty to join. Slifer Red can be entered by everyone who wants, Ra Yellow can't be entered. Obelisk Blue can only be entered by passing the written exam and the practical exam, which is a 3 duel battle with an Academy representative. The virtual battles are done with the help of KCVDS or J_PROJECT.
Slifer Red students must collect +200 points in order to get to Ra Yellow. Ra Yellow must collect +400 points (the +200 points from Slifer do not disappear). Obelisk Blue students are collecting points as well. After collecting +600 points they are able to move up to the Secret Faculty.
