How has the new Math SAT topics differed from the old SAT, what topics were terminated?

I’m just wondering, because I’m practicing on a few old SAT tests and a few of the questions I don’t recognize as being one of the four topics.

There are no more counting/permutation questions. And really no more of the random logic puzzle type questions. Can you describe some of the questions you are talking about? Also, the best indicator is: did anything like this appear on the official tests 1 - 8?
