When I graduated college my overall GPA was a 2.24… Now I want to go back to school and get my OTA degree and I need a 2.5 to apply to the program. How many years/classes would I need before i can apply?
That seems like a relatively simple calculation that you could do on your own, especially since you are the only one who would have the kind of information needed to answer it.
^Yes, this. You need to know how many credits you have, your grades in each class (grades are weighted differently depending on how many credits each class was), and how many credits the remaining classes are worth. There are some online calculators that will allow you to plug in values to figure this out.
Also, keep in mind that just because you hit the program minimum doesn’t mean you’ll be admitted. Medical professional programs, especially, tend to be competitive; often the average GPA for admitted students is higher than the minimum - sometimes much higher.
