I know at least 2 of my letters look NOTHING like that, lol.
I used 2 math professors, and I didn't show them my grades, GRE scores, didn't tell them ANYTHING about economics etc (even though I have a near 4.0 GPA and an 800). Correction: I remember telling one of them what my statistics were, but not the other.
Anyway, I wonder what they wrote.
P.S. Don't lose hope.
