I heard Math Destroyer is very similar to the real DAT....
Just memorize some conversions and trig problems then you will be fine
Here is my breakdown for math destroyer so far.
1 - 20
2 - 22
3 - 23
4 - 23
5 - 23
6 - 26
7 - 26
8 - 26
As you see, you will be used to the problems and get used to the types
of questions that they are asking. So don't worry too much.
Tips - If you encouter hard problems that you think you cannot solve it within 1 min, just skip the question and try to come back later
