that's r factor, to get direct correlation or whatever you need to square that number, which gives you like .21, supposedly .16 of that is directly related to LSAT, the rest the UGPA.

This.

Simply put, if the correlation coefficient is .46, then 21% of the variance in first year grades can be explained by the regression model (UGPA+LSAT).

The correlation is high enough to make the LSAT a remarkably good admissions tool. That you can find any single predictor with such a high correlation to something like law school grading is pretty amazing.

From the standpoint of trying to grant yourself some kind of competitive advantage, however, the correlation is dismally low. It makes almost no sense at all to factor it in.

As an illustration imagine just assuming that you will be an all-star in the NBA because you are tall. It's not that extreme of course but you get the idea.
