The previous comment simply was not true. Though it is generally wise not to take the test when completely stoned, medicated or drunk, there obviously are things that you can learn.
Firstly, the questions follow a logical pattern. For example, the prime numbers, squares, cubes, or addings.
The patterns too have a logic to it, as do the words and math tests.
If you are used to making simple calculations without pen and paper, surely you have an advantage.
All in all, it is fairly clear to me that you practice to the test, which is supported to by the original posting. But hey, you are free to make up your own mind. Either the two of us (and our reasoning) is correct or the other guy saying it just ain't so.
