Thank you very much for your response. I saw on the internet that as long as you had less than 24 college credits you're fine, but the headline was "from High School Student to College student", so there's definitely some truth in what you're saying. I will call them directly.
And thanks for your kind and encouraging words. To be honest, I do feel a bit old to go into med and I looked into nursing school instead, but I didn't find it so fulfilling for me. I need more science and theory. I decided to go for the medical program since I'm single, I have no kids and it's been my dream.
