That software is utterly pointless....
The aptitudes are designed to not only test ure natural aptitude, but also youre improvement as you repeat the tests for a second and third time...
Getting good at certain tests before stage 2 will not be beneficial!
Also, the hardest tests are not included in the software according to those who did waste their money.
Everyone in my morning group bar 1 person passed stage 2!... you'll be fine!
