When did you graduate from college? Quinnipiac requires that you have taken the prerequisite classes within the last 7 years. CWRU is 5 years. I ask b/c you said you've worked for 14 years as an RT. So it sounds like you've been out of college for awhile. You'll need to re-take all of those pre-req classes if it's been longer than 7 years since you've taken them. Forgive me if you already know this.
With your 14 years of clinical experience, I'd say you are a VERY good candidate! If you do have to re-take those classes, don't let that stop you. My husband did just that! He too was a RT and spent the last 3 yrs working and re-taking all of the pre-req classes, and he just started at CWRU Houston last month. Plus, we have 2 kids! I'm a little proud of him! All that to say, if you want it bad enough, GO FOR IT!
