You don't say why they are "postponing" your acceptance - it could be because they have too many applications or the performance level is high - it could also be because they have to limit admissions for some other reasons. You should not only talk to your counselor, but look at the college catalog and see if they have any 'probationary" or "conditional" admissions - some schools have policies for admitting students who are around the borderline of the grade/test minimum requirement.
You could always email the department you are interested in as well - even as a starting college student, it's not a bad idea to let the department know you are impressed with what they have to offer. . .and it helps get your name in their mind. Tell them about your interests and why you are attracted to that department. It might not change anything but they'll know you are interested and will sometimes remember that later. . .
Counselors at the high school level hardly ever make this suggestion, but it also wouldn't be a bad idea for you to pick a company/profession that is doing the work you want to study, and just send them off an email, or better yet, a snail mail, asking them for suggestions in how to prepare yourself for the field and what experiences they look for in new college graduates. That might help you plan out things through your whole four years and put you in a good position when you start looking for jobs and internships. It might take awhile to get a response, but you might be surprised how many professionals out there will take a few minutes to make suggestions.
