TLI FAQ

Remember, the TLI test today was a PRE-test. It is ok if there was something you had not seen before the test. I didn't help anyone because I wanted to see what you knew and what kind of reasoning/test taking skills you have. We will get to everything on the test some time this year. I will cover it in detail then. For now, here's a quick run down of the "weirdest" stuff.
