Thank you for sharing! This is very interesting!
Unfortunate we can't really compare 1 mistake on the test - there are different sections and different difficulties of questions.
But here are some clues/things I have observed:
You left the last question unanswered. That has a HUGE impact on the Focus. You lost 4-5 points on that one.
The most interesting aspect to me is your DI performance and why it was so inconsistent. You got very different scores in Test 1 and Test 2. Did you take these sections in a different order? The only explanation for having such different scores on data insights is that you got an easier section in one case and the harder section in another which means these must’ve been taken second or third.
Because of your performance in the first section, your (second) section started with easier questions (fewer hard questions, means mistakes are more painful) which also caused your third section to start out easier as well and similarly carry s steep penalty for any mistake... 😥 (this is my understanding of the algorithm which is still evolving as I am taking more tests and have more data points).
In terms of how to score better, I have not run all the experiments yet to try different scenarios so I appreciate your example here. I don’t know what was the time between the two tests and why your performance on the data insights was so much better than one than the other…. I think that’s the biggest question.
