I am planning on taking the Science pre-recs over the next two years. I already have most of the non-science pre-recs (English, humanities). But I took these classes between 1999 and 2003. Have you heard of any schools which require you to retake these classes as well? I saw that some colleges would want you to retake you science classes if you took them 5 years ago. I'm hoping this doesnt apply to the non science classes.
