You need to talk to the universities. They will decide if they want to admit you in light of your results (it's possible you might not be declined if you miss your grades by a few points). If the universities reject you, it will be necessary to look elsewhere or re-apply after re-sits. Ask if they will accept you based on your results. If not, ask if they will consider you if you reapply after re-sitting your exams. See more about results day.
