What is the difference between weighted and unweighted GPA?
Unweighted GPA treats every course on the same scale, usually 0 to 4.0, regardless of difficulty. Weighted GPA gives extra points to honors, AP, or IB courses, often pushing the maximum to 4.5 or 5.0. US high schools commonly report both, and college admissions look at unweighted GPA alongside course rigor. The calculator supports both modes so you can match what your school uses.
How are credit hours used in the calculation?
Each course's grade points are multiplied by its credit hours, all those products are summed, and the total is divided by the sum of credit hours. This means a 4-credit course affects your GPA twice as much as a 2-credit course at the same grade. Enter credits exactly as listed on your transcript so the result matches what your registrar will compute.
Does it work for the UK, India, or European grading systems?
The calculator uses the US 4.0 scale by default. UK degree classifications (First, 2:1, 2:2, Third) and Indian percentage or CGPA-on-10 systems do not map cleanly to 4.0, but you can convert manually using common tables: UK First equals roughly 3.7 to 4.0, Indian CGPA on 10 is often divided by 2.5, and European ECTS grades A through F line up close to 4.0, 3.0, 2.0, and so on.
How do I handle pass/fail or audit courses?
Pass/fail and audit courses are usually excluded from GPA because they do not have letter grades. Leave them out of the calculator entirely. If your transcript shows a pass with a credit value but no grade points, including it would dilute your GPA incorrectly. When in doubt, check your school's GPA policy, as some institutions count a fail as a zero.
Can I project my GPA for next semester?
Yes. Enter your current cumulative GPA as a single line with your total credits earned, then add each upcoming course with the grade you expect. The calculator will produce a new cumulative GPA assuming those grades. This is useful for figuring out what grades you need to reach a target, such as the 3.5 cutoff for many honors programs or graduate school applications.
What grade-point values does the calculator use?
Standard US scale: A equals 4.0, A minus equals 3.7, B plus equals 3.3, B equals 3.0, B minus equals 2.7, C plus equals 2.3, C equals 2.0, C minus equals 1.7, D plus equals 1.3, D equals 1.0, and F equals 0.0. Some schools use 4.33 for an A plus or skip plus/minus entirely. If yours differs, override the points on each row to match your transcript exactly.
