They gave you a GREAT bit of feedback!! Kudos to them!
NOW..if you wish to reapply (I did, many years ago after I got the TWEs...), go ahead and start it...maybe wait until next month or so...
Now...what can YOU do to make your package more attractive given you're in a very competitive state? The answer is probably multifaceted. You could, of course, retake SAT/ACT and blow them away with BIG numbers!! Or you could enroll in college (big or community) and take the same schedule you'd take as a plebe/doolie...and crush the grades! Do that and you remove the biggest question they have: can you succeed academically?
And of course, stay in the best physical condition you can!
Easy, eh?
