<p>Mootmom is right - if a high school student takes college courses under a dual-enrollment program, it should not affect their status as a freshman applicant. There’s only a problem if they take college courses as a regular college student. Definitely contact MIT admissions for the official word, but how the student is classified while they are taking the college courses has a lot more to do with it than the total number of credits, which may not matter at all. (if it does matter, your brother can always audit next year).</p>
<p>Here’s what MIT says in their transfer applicant FAQs, towards the end of the page at
<a href=“MIT Admissions”>MIT Admissions; </p>
<p>“I have been attending college during my senior year in high school. Can I apply as a transfer?”</p>
<p>“No. If you are still in high school, you are considered a freshman applicant regardless of how many units of study you may have taken at the university level.”</p>
