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 mixes straightforward questions with a few that need an extra step, so it works well as a checkpoint once the basics are comfortable. At 25 questions in 40 minutes, you have about 96 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
