GPA 是怎么算的
每个字母等级对应绩点（标准制 A = 4.0），乘以课程学分得到质量点。总质量点除以总学分 = GPA。加权 5.0 制下，AP/IB 课程多加 1 分（A = 5.0），奖励选了更难课程的学生。
学期 GPA vs 累计 GPA
这个计算器算的是学期 GPA。算累计 GPA 时，把每个已完成的学期当成一门“课程”：成绩填该学期 GPA，学分填该学期总学分。（本质是加权平均：各学期 GPA×学分之和 ÷ 总学分。）
多少 GPA 算好？
On a 4.0 scale, 3.5+ is generally strong for college admissions and scholarships; 3.0+ keeps most doors open. Graduate programs often look for 3.5–3.7+. Context matters — course rigor, trends over time and your major all count alongside the number.
常见问题
What is the difference between weighted and unweighted GPA?
Unweighted caps at 4.0 regardless of course difficulty. Weighted (often 5.0) adds a bonus point for AP, IB or honors classes, so it can exceed 4.0.
How do +/- grades affect GPA?
Typically A− = 3.7, B+ = 3.3, B− = 2.7, and so on. Uncheck the +/− box if your school uses flat letter grades.
Can I calculate cumulative GPA?
Yes — add each completed semester as a course row: set credits to that semester's total and pick the grade closest to its GPA, or compute the weighted average manually.
Is a 3.5 GPA good?
Yes, on a 4.0 scale 3.5 is solidly above average and competitive for most colleges and scholarships.
Do colleges recalculate my GPA?
Often yes — many strip out non-academic electives or re-weight AP courses their own way. Your transcript GPA and their number can differ.
