If you’re looking for the most bang for your buck, then start fool proofing logic games. The core curriculum explains the concept of “fool proofing” and, in my experience, most people can pick up points in LG pretty quickly.
Congrats, especially for that impressive 16-point jump (In fact, the hardest 16 points to achieve)! A demon is keeping me from 180. I've had 3 179s and nearly 10 177's or 178's. Hope to join your club soon, several times over before August in fact!
