Is a 3.4 GPA Good?
A 3.4 GPA on the unweighted 4.0 scale is roughly a B+ average — about 90% — and it is comfortably above the typical US college average (around 3.1) and competitive for most graduate programs and internships.

Context that matters more than the number
GPA is read alongside course rigor and trajectory. A 3.4 earned in a demanding major with an upward trend reads better than the same number from an easy schedule that's sliding. Mathematically, raising a 3.4 takes time: one straight-A semester of 15 credits moves a 60-credit GPA by only 0.12 points — which is why starting the climb early beats a senior-year sprint.

Common questions
How are letter grades calculated from percentages?
Most US schools map percentages to letters in 10-point bands: 90–100 is an A range, 80–89 a B range, 70–79 a C range, 60–69 a D range, and below 60 an F. Plus/minus splits each band roughly in thirds (e.g. 90–92 = A-, 93–96 = A, 97+ = A+). Individual schools and professors can and do vary the cutoffs.
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.
