a few transfer questions?

<p>ok so i'm a freshman at texas state university-san marcos right now, i got rejected to a&m last year, but i want to apply as a transfer. i was wondering if
1. how early should i apply?
2. is it like high school where all the good majors get filled up for late applicants?
3. how hard is it for an average transfer student to get into engineering (computer science)</p>

<p>thanks</p>
