What should I do in the meantime?

I’m 24 years old and about to start applying for rad tech programs in a few months. I will apply to every program in the area that be community colleges or private programs.

My grade average is a B and I understand that the admissions to the program are extremely competitive and that I’ll most likely have to wait a couple of cycles.

While I wait to get admitted, should I go back to university and aim at getting a teaching credential(i would go from full time to part time at my job)

Or just continue working full time hours until I get admitted to a program?
