<p>Is he considered a student of that college, or a student at his HS? I think that’s the important question, and it is probably a good idea for him to talk with someone in Admissions rather than speculating here on CC. Many MIT freshmen have taken college courses, either on campuses or via online methods, before they arrive at MIT, this is not completely unusual. If the student has not been a registered college student and has only been taking courses there to supplement a lacking HS curriculum – it may not “count” as being a current college student and hence may not affect applying as a freshman. This is a question for Admissions, I think.</p>
<p>Also note, “college credits” for classes taken in HS do not automatically directly transfer in at MIT for incoming freshmen. There are requirements to document the course curriculum, sometimes to do the entire year’s worth of problem sets for the equivalent MIT course, and then to take an exam during Orientation (usually the final exam from the MIT course) to qualify for outplacement. So having college credits on one’s HS transcript does not automatically place a freshman out of an MIT course.</p>
