A sample question from this test
What is the least number that must be added to 470 so that the sum is exactly divisible by 16?
- 8
- 9
- 10

Answer: C. 10. 470 ÷ 16 leaves remainder 6, so the number to add is 16 − 6 = 10.
How to approach this test
Use remainders and cycles: unit digits of powers repeat in short cycles, and divisibility rules save long division.
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 50 questions in 50 minutes, you have about 60 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
