Does the school offer financial aid?
No. We don’t offer financial aid because we’re free. No, really: completely free.
Do you offer industry certification?
No. We are not certified yet, so we can’t offer that to students. What we do offer is knowledge and understanding of a trade.
Enroll first in the trade you’re interested in. You get your key, your program opens, and you begin studying.
