Mentioning one’s IQ tests results is just gauche.
Unless one is specifically asked for an IQ test result on the application or during the interview, it is in poor taste to include it. Furthermore, OP’s IQ test score is not out of the stratosphere relative to the applicant pool.
OP’s grades, test scores, and teacher recommendations are sufficient to indicate that OP is academically capable.
OP should focus on actual accomplishments and interests - things that paint a picture of her as an interesting intelligent person.
