Hi Mike –
My responses to your three questions:
1. Yes, I have taken a proctored LSAT exam (offered by a preptest company in my city) but not one administered officially by LSAC. So if I took it, the December exam would be my first official one.
2. Realistically, I would say I’m 10-12 points away from my goal score of 167-169.
3. No, there is no pressing need to go to law school next year. It’s more important for me to attend a better school to the point that yes, I would be willing to wait an extra year if I had to.
