Admission officials at your potential transfer colleges will pay far more attention to your college grades than to your high school grades, especially those from 9th and 10th grades, so you’re in good shape there.
Although SAT scores don’t play as big a role in transfer admission as they often do in freshman admission, they can count. Is your 1250 SAT score from just the Critical Reading + Math sections of the test or from the Writing section as well? If it’s the former, then there’s probably no need to re-test. But if you got 1250 on all THREE sections of the test combined, it would be wise to try once more … IF you think you can improve (which, most likely, you will since you’re taking challenging English and Math courses now) and IF your transfer college requires SAT scores from its applicants.
You also might want to consider spending one more year at your community college rather than trying to transfer soon. There tend to be greater transfer opportunities for community college students who have completed two years and earned an Associate’s degree than there are for applicants who have only completed one year. In particular, many four-year universities have “Articulation Agreements” with two-year colleges that guarantee (or at least facilitate) transfer admission to students with an Associates degree who have fulfilled certain course requirements.
Also, since your academic record has risen steadily since you began high school, an additional strong year under your belt at the CC will make you a more attractive candidate to your prospective transfer schools. Moreover, some four-year colleges will require SAT scores from transfer applicants who have completed only one year of college and do NOT require SAT’s from those with an AA degree. (You’ll need to check Web sites for each transfer college you’re considering to see what the testing policy is. Also check to see what the median test scores are at each college. If yours are below the median, you should definitely re-test or wait until you’ve had two years of community college before transferring.)
You certainly can apply to transfer to a four-year-school in your freshman year, but do give a second year at the community college some consideration as well. You’re clearly on a roll there!
Good luck whatever you decide.
