SAT Subject Tests for ED2

Hi, I’m an international student. Due to time limit, I couldnt prepare for the SAT or ACT but SAT Subject Tests. Did anyone here apply to Colby with the option of 3 SAT Subject Tests? Is it okay if I apply in this way? I’m so worried… I intend to apply in the ED2 round… cause I know the ED 1 is too hard (maybe it’s only for special guys)…
