Hi, I am a single mother of 2 and am currently finishing up my pre-med pre-req's. I am a registered nurse at the moment and have taken my bio, anatomy, physiology, and gen. chem quite awhile ago. By the time I apply some of the classes wiill be almost 10 yrs old. Does this matter or will I have to repeat them? I have not yet taken the m-cat and my gpa is 3.7.
