If u apply to the same school again do they even consider you? I plan to apply to the same schools again but in July..bc this year I applied in February and apps weren't reviewed until march 🙁!
Do you need more science classes? Do you need to retake the OAT?
If you've been interviewed before, I'm sure that volunteering/working would be a better use of your time than more classes. Did you talk to the schools about how you can improve your application?
The doctors I worked with said that if you are rejected from a school, don't try again. If they don't want you, then you don't want them. If they don't think you are a good fit for their school, then you don't want to go there.
Look into other programs when you apply next year.
