Ultimately, colleges don’t want to know what your IQ is. I am willing to bet if you had a kid with an IQ of 100 but worked super hard all through high school he would get into some great schools. On the other hand, (not implying that this is you) if you have a kid with an IQ of 150 who did nothing at all in high school but cruise along, he probably wouldn’t get in. My point is, colleges care less about what your intelligence may be… they care much more about what you do with your intelligence. As long as you have good grades and good extracurriculars, there’s no need to tell colleges your IQ, they should already know that you are intelligent simply by looking at your resume.
All the luck to you in your college applications!
