I feel the math portion at the end of the DAT destroyer book ( the one that has 117 questions + the 20 quantitive comparisons questions ) was very similar to my test, but again some questions were similar to the questions from the Math destroyer book.
All in all, you can't go wrong with these math problems, you just need to do them once or twice, then you need to take some timed tests to get used to time management and keep on practicing so you don't lose what you learned.
I did some tests with Kaplan and some tests with Bootcamps, they teach you about time management.
But, no matter how prepared you are, there will always be 2-3 questions that you have never encountered before and now the real questions are gonna be:
Are you gonna be smart and try to solve them and lose the points on easy ones?
or
Are you gonna be smart and guess + skip them and get the points on the easy ones?
Choose what kind of smart you want to be.
