Frumnot: He posted later that his friend took college as a joke.
I don’t see any purpose in arguing whether you did or didn’t score in the 170s without major studying. All I know is that the people I know in real life whom I thought were smart before they applied to law school spent significant time studying and scored in the 170-180 range, but mostly closer to 170, after having studied a lot. Also, I can’t tell from your post what conditions you got your score in, but there’s an exponential difference between getting in the low 170s while meandering through four sections one at a time over the course of a day, and taking five sections consecutively under test day conditions.
If it’s true that you did it under the right conditions, then I would suggest you study more, get your 180, and go to Harvard.
