Whats my next step towards TESC?

If I were in your shoes, I might hold off on applying. I'd look at plans, see what I need, and test as much as possible. Then, when I was close to getting everything that I needed, I'd apply. Then, enroll. Regardless of what you do, good luck.

I'd do the same exact thing as LaterBloomer just stated.
