<p>As you said, transfer admissions are very, very difficult. More competitive than freshman admissions. I do, however, know someone who was accepted as a transfer student (she had second thoughts and didn’t end up transferring, but she’s now at MIT as a PhD student).</p>
<p>Her grades were good, but, if I remember correctly, not phenomenal. However, she already had extremely good research experience, and had taken a couple of MIT classes as a cross-reg student and gotten As. No clue what her test scores were. But the fact that she would be behind others from her year was one of the reasons that she opted not to transfer after all.</p>
