Cách tính điểm hoạt động
Most grading systems use weighted averages: each assignment category (homework, exams, projects) has a weight reflecting its importance. Your final grade = sum of (category average × category weight).
Example: Homework (20%): 92 average. Midterm (30%): 85. Final (40%): 78. Participation (10%): 95. Final grade = (92×0.20) + (85×0.30) + (78×0.40) + (95×0.10) = 18.4 + 25.5 + 31.2 + 9.5 = 84.6 (B).

US 4.0 scale: A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D = 1.0, F = 0.0. Some schools use a weighted GPA where honors/AP classes add 0.5–1.0 points.
International equivalents vary widely. A US B (3.0) roughly corresponds to: UK 2:1 (60–69%), German 2.0–2.3, French 13–14/20, Australian Distinction (75–84%).

To calculate the minimum final exam grade needed: Required final = (Target grade − current weighted total) / final exam weight.
Example: You want a B (80%) overall. Current average (excluding final): 76% on 60% of the grade. You need: (80 − 76×0.60) / 0.40 = (80 − 45.6) / 0.40 = 86%. You need 86% on the final to get a B overall.
Frequently Asked Questions
Điểm trung bình có trọng số và không có trọng số là gì?
Unweighted GPA uses the standard 4.0 scale for all classes. Weighted GPA gives extra points for advanced classes (AP/IB/Honors) — typically up to 5.0. Colleges generally consider both but weight course rigor heavily in admissions.
Tôi có thể tăng điểm trung bình của mình một cách đáng kể trong một học kỳ không?
It depends on how many credits you have completed. Early in college, one great semester has a big impact. By senior year, the effect is much smaller due to the large number of existing credit hours. The formula: New GPA = (old GPA × old credits + new GPA × new credits) / total credits.
Tôi cần GPA bao nhiêu để học cao học?
Varies by program. Competitive PhD programs often expect 3.5+. Most master's programs require a minimum of 3.0. Professional schools (law, medicine) are highly competitive (3.7+ is common for top programs). Research experience and test scores also matter significantly.
