Be boring and buy it for 6540 robux. Why? It only takes a few weeks to get it if you do it right.
Not be boring and work for SI. My recommendation is do Shifts until you’re Warden as that’s the highest rank you can get with Shifts. Shifts may be boring but they’re easier then Trainings cause you just need to talk a lot to pass, and they take less time. After you’re Warden (Remember your CDs,) attend a Training, pass Faces, Accuracy, and just know a little bit about the game, and there you go, you’re a hungry white shirt begging for co-hosts/helpers. You’re welcome.

CAO and CO: 2 days
ERT and COMM: 3 days
PI and DW: 5 days
W: 1 week
These Cooldowns mean that they end 2 days or whatever your CD is after you’re promoted. For example, if you get Warden, then your CD will end on the 7th of you becoming a Warden. Hope this helps!
