Common questions
Does the GPA calculator work for weighted grades?
The GPA calculator uses the grades and credit hours you enter with the grading scale you select. Schools treat honors, AP and plus or minus grades differently, so check your school's scale and confirm your official GPA with your registrar.
Can I rely on the citation generator for my bibliography?
Use it as a starting point. The Citation generator formats the details you provide and does not invent missing information. Check author names, dates and titles against the source, and confirm the result matches the style edition your instructor requires.
How is typing speed calculated?
The Typing test uses one consistent words per minute formula for every run and also reports accuracy. Comparing both numbers shows whether a faster score came at the cost of more errors, which matters for real typing work.
