How to approach this test
Decide first whether order matters (permutation) or not (combination). Repeated letters divide the count by the factorial of each repeat.
This set leans hard, with multi-step questions, so treat it as a stretch: attempt the questions you can see a method for first and return to the rest. At 10 questions in 15 minutes, you have about 90 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
