Hi Visesque,
If you have not yet done so, then you should reach out to the Support Team (at
[email protected]) with any issues that you might be having. You can also fee free to email/PM me with any questions that you might have.
While the Scaled Scores on this recent CAT are a bit different from your initial CAT, they essentially show the same general performance. This means that you're 'seeing' (and responding to) your CATs in the same way as when you started, so there are some fundamental issues with how you work through your CATs. THOSE issues are leading to the little mistakes and lack of improvement.
On this CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just didn't know how to do?
3) Because the question was too hard?
