**A Student Scores 85, 90, 78, and 92 on Four Tests—If the Final Test Is 88, What’s the Average?** What does a consistent 85, 90, 78, 92, and 88 say about one student’s academic performance? At first glance, the range between the lowest (78) and highest (92) scores suggests variability—good effort in some areas, room to grow in others. But calculating the true average reveals a clearer picture of overall performance across all five assessments. For students, parents, and educators tracking progress, understanding how to interpret composite scores helps guide future study, test prep, and goal-setting—especially in a competitive, results-focused educational landscape. Understanding the Average Scores: The Math Behind the Curiosity A typical mean is calculated by adding all test scores and dividing by the number of assessments. Here, the four known scores are 85, 90, 78, and 92. Adding these together: 85 + 90 + 78 + 92 = 345. Adding the final score of 88 gives 345 + 88 = 433 total points across five tests. Dividing 433 by 5 results in an average score of 86.6—commonly rounded to 86.7 or 87 when reported. This average reflects a strong overall performance: well above the typical passing threshold and a solid indicator of balanced capability across diverse subjects or skills.
