I took my SAT Achievement Tests one dreary Saturday morning in November 1983. These were the scores that were going to determine my eligibility for "top-tier" schools like Caltech, MIT, and Harvard (all of which I applied to, why I still can't fathom.) Sitting next to me was a dipshit who, for the entire test of four hours, sniffled like an elephant who desperately needed Afrin.
By the end of the four hours, the entire room wanted to either scream at him or beat him senseless.
I do not recall anyone blaming that environment for their performance on those tests. Nor should they have.
Memo to LSAT weenie: suck it up, buttercup.
