After everything is green, the next step is to keep your grades up, ENJOY your senior year, take the ACT again (as you stated), make sure you have Plans B, C, D in the works (did you apply for the AROTC scholarship? apply to & visit those schools?), stay healthy & injury free.
Control what you can; have patience for what is now out of your control. You may hear something soon, OR you may not hear anything until March / April. My DS received a BFE, with no advance warning, one Saturday morning in January. Until you receive that TWE, you are still being considered.
Good luck!
