You cannot go ROTC to WOFT. Once you graduate and commission assuming you get aviation, (one of the most competitive branches) you won't be able to go Warrant until your service obligation is up, at minimum 6 years. There are rare exceptions to this policy, but don't expect to be one of them. You also wouldn't go to WOFT, you just become a warrant. at that point you're an O-3 ish and its a significant pay cut for a little less work and a few more flight hours.
If you want to be flying in any capacity out of ROTC right now you should ensure you're top 10% DMG. Current accessions model has SIFT score not factored into accessions as long as you pass. Maintaining a 4.0 gpa and 500+ ACFT should be your priority right now. If you're in a hard major, switch to something easy.
