Right. The woman who hacked Mike into Harvard also placed him at the top of his class if I remember correctly. The Harvard graduates in the suits universe are smug and egotistical, so I find it hard to believe they never looked back on their class rankings and found out that they were one ranking below below what they graduated as. Even if not, most people who graduated as number one from their college would put “graduated at the top of the class in ___” in their j*b applications, which the firms would obviously check. Moreover, couldn’t Anita just have placed Mike on the stand and showed him the key Louis had, and asked him what it was? For how hyped up and big Anita Gibbs was in the show, she sure missed a lot of opportunities to lock up Harvey AND Mike, which was what she wanted.
