<p>You can review MIT's credit policy for AP, IB, and A-level exams here. You may also want to review MIT's General Institute Requirements (GIRs) here, which is roughly equivalent to its "core requirements".</p>
<p>There is no such thing as "AP English 12" (unless that's what your school calls AP English Literature or Language). If you take either of those exams and score a 5, the requirement to take the Freshman Essay Evaluation (FEE) writing test over the summer prior to your MIT freshman year is waived. (Your performance on the FEE determines whether you are required to take a writing-intensive humanities class your freshman year. If one of your AP English scores is a 5, it is as if you passed the FEE without having to take it.)</p>
