I second Vera's comments.About three weeks ago I was missing, on averaging 40-60% of the questions in Games (so 9-12 wrong). I picked up the LGB, went through it in 3-4 days, and took a practice section. I got a perfect score. I've taken three practice tests and a few practice games sections by themselves, and I've yet to miss more than 3.For me practice will solidify. I kind of liken it to the following analogy: the LGB will give you the tools, but practice will give you the skills to use those tools.REDO your games, indeed.
