Shall We Try Again?
You didn't pass this one. But it's not about passing or failing, it's about learning and trying again! Failing is how we learn to do better. So look up the material a bit and don't quit!
Good Job!
Really good job, you got more points and answered more questions correctly than 80% of people taking this test. You don't have much to learn here, but have a look at those you got wrong and try to figure out why that happened.
How Impressive!
Wow, your logic is impeccable! How did you get so many correct, all in your head? You must have a quick and agile brain or maybe you love logic questions. We're super impressed!
