CALS Transfer Required Courses

Does anybody know if it’s possible to still be accepted as a CALS transfer even if you haven’t completed the required courses? I know they say the “most competitive” applicants have completed the required courses, but is it still possible? I was accepted for the Spring semester but am not able to attend for financial and personal reasons. I tried to defer but they just shot me down. I will have all the other courses completed except for Physics I & II (calc-based). I plan to take these courses over the summer however before the fall semester starts. Anybody have experience with this?? Thanks!
