It all depends on your target law school. For example, if you want to get into a Tier 4 or Tier 3 school, then scoring in the 150s would be a good score. If you want to get into the Tier 2, however, then you would have to get a much higher score than a 150. And the score needs to get higher as you continue all the way up to the T14.
Anything 165+ will open a lot of doors for you.
