A sample question from this test
How many different arrangements can be made using all the letters of the word DOCTOR?
- 362
- 360
- 350
- 358
Answer: B. 360. There are 6 letters with repeats, so arrangements = 6! ÷ 2 = 360 (the divisor is the product of the factorials of the repeated letters).
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 easy, so use it to confirm that you can solve the basic pattern accurately before you move to harder sets. At 30 questions in 45 minutes, you have about 90 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
