Common questions
Is a 3.5 GPA good?
On the standard 4.0 scale, 3.5 sits between an A- and B+ average — comfortably above the typical US college average (around 3.1) and competitive for most graduate programs, internships and scholarships, though the most selective programs skew 3.7+. Trend matters too: an upward trajectory reads better than a flat one.
What's the difference between weighted and unweighted averages?
An unweighted average treats every score equally: add them up, divide by the count. A weighted average multiplies each category by its share of the grade first — homework 20%, midterms 40%, final 40% — which is how most courses actually work. If your syllabus lists category percentages, you need the weighted version.
