They are both mandatory resources if you haven't already checked them out. They can give you a relatively realistic perspective on where you stand.
Otherwise, you are in good shape. Especially if you can raise your score 3-4 points. The difference between a 164 and a 167 is pretty substantial. Not only would it get you accepted to schools you would otherwise be on the fence for, it's going to garner you way more scholarship $$$ from admitted schools. I highly recommend studying hard (2+ months) and retaking. Good luck!
