Brain Training

So I've been going through training to become a "brain trainer." It's getting to play brain teasers and mind benders with other people, mostly kids and getting paid. If I pass the rest of the certification process, it's onsite training for the facility. To help improve me for the job I was told to play certain games at home, such as tetris, bejeweled, DDR, etc. It's a pretty cool gig. Now to study the procedures and materials to make sure I ace the practical exam and written portions.
