GED® Mathematical Reasoning: Full-Length Practice Exam (Level 4 - Mastery)

The final and hardest of the four full-length GED® Mathematical Reasoning practice exams, for students aiming at a top score after clearing Levels 1-3. Same test-day format -- 46 questions in 115 minutes, a no-calculator Part 1 (the first 5 questions) then a calculator Part 2, with a provided formula sheet, scored 100-200 (145 to pass) -- but every single item is a hard, multi-concept problem at the ceiling of the GED®'s range: fractional and negative exponents and nested radicals, semi-annual compound interest, reverse pricing, dilution to a target, marginal tax brackets, inverse variation, multi-leg average speed, conditional probability, combinations and expected value, hemisphere-on-cylinder volumes, annulus area and volume scaling, the quadratic formula, line-parabola systems, factoring by grouping, rational expressions, quadratic and absolute-value inequalities, function composition, exponential thresholds, and arithmetic sequences. Every question includes a worked explanation and a pro tip.
