@JTT,
Yes it is, but we're talking about students hugging the "bottom of the class."
That used to be me through high school.
Also, there's a current magazine that lists the preferred colleges and universities, their SAT/GRE scores, admissions, and rankings. I was surprised to see CIT higher than MIT or Harvard. Of coarse, Harvard, Yale, Stanford, Cal Berkeley, and some others are always listed as the place to get your education. I was never in that league, so attended Cal State Hayward when it was a small school (less than 3,000 students), but got a pretty good education, and had four job offers before I even graduated (because it had a good reputation for accounting grads).
Some of us who didn't do well in grade school ended up doing better than average in our work careers, and I believe that's what counts.
Study hard, and work hard; it pays off.
