Hi run,
First of all, congratulations on an excellent score! It sounds like you are well on track to a 175. Take a moment and pat yourself on the back because we are thrilled at scores that high!
During these last three weeks before the LSAT, you will want to put some finishing touches on your strategy. It sounds as though your timed drills for LR and LG have certainly paid off, so obviously continue with those. Continue to reassess yourself as a test-taker, identify your weaknesses and drill, drill, drill your weakest question types and game types. Perhaps challenge yourself with the 12 Hardest LSAT Games ever if you are feeling up to a good workout:

And remember after studying, take some time for yourself and mentally recompose. It's easy to get overzealous with this exam, so take a day off this week and recenter.
In addition, you will want to do practice tests at least twice a week to make sure that you are keeping yourself at a high performing level. Regular practice tests will also increase stamina and confidence. And my favorite piece of advice comes from my Powerscore's Nikki Siclunov who discovered that he only started scoring in the high-170's when he stopped trying to get a 180!

So drill hard, PT harder and relax when you need it. And for the next PT? Don't go for perfect! Realize you are going to miss one or two and have some fun with it! You may just find that's the extra bump you want.
