Dual-N-Back

 I've heard that Dual-N-Back is an excellent way to increase fluid intelligence as well as memory so I thought I'd give it a shot. Since I'm concurrently working on my memory via Lumosity I limited my number of sessions/day to 12 for purposes of not overtraining as well as time constraints.

 

The website used to find this exact program is https://brainworkshop.sourceforge.net/

I'll update my improvements at reasonable intervals.
