**Why Students Scoring 85, 90, and 95 Are Rethinking Final Exams—and How to Reach That 90 Average** In today’s competitive academic climate across the U.S., students and parents are increasingly focused on navigating grading systems that weigh term performance differently—especially when high-stakes final exams count double. As.Test tools, educators are seeing a rising pattern: when a final exam counts twice as much as each test, even strong midterm scores may fall short of a target average. This dynamic is prompting curiosity: *What final score is needed to earn an average of 90 when three tests score 85, 90, and 95—and the final counts double?* Understanding how averages work is key. In a weighted scoring model, the final exam’s doubled weight amplifies its impact on the final grade. With three midterms each worth 20% (60% total) and the final doubling, the final’s weight becomes 40% of the overall grade. To maintain a 90 average, the weighted total of all scores must equal 90 points across 100 points available. **How A student scores 85, 90, and 95 on three math tests.
