AMC 8 Strategies

Test-Taking Strategies

StrategyDescriptionTips
Time Management~1.6 minutes per problemSkip hard questions, return later; don't spend more than 3 min on any problem
Process of EliminationRemove obviously wrong answersEliminate 2+ choices → guess; no penalty for wrong answers
Work BackwardsPlug answer choices into problemStart with middle value (C); often faster than solving forward
Smart GuessingLook for patterns in answer choicesA, B, C more frequent than D, E; if stuck, choose C or B
Draw DiagramsVisualize geometry problemsLabel known values; look for symmetry and similar triangles
Simplify ProblemsReplace large numbers with small onesUse unit ratios; look for hidden "nice" numbers
