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 20 questions in 20 minutes, you have about 60 seconds per question on average. After you submit, review every wrong or guessed answer using the explanations.
