Frequently asked questions
What does a two-quarter exam calculator do?
It combines two quarter grades and one exam. Each score uses its assigned course weight. The result estimates your overall course grade.
Must all weights total 100%?
Yes, standard weighted calculations require a 100% total. This tool can normalize other positive totals. Check your school policy before normalization.
Can it find a required exam score?
Yes, select the required exam calculation mode. Enter your desired final grade target. The tool reports possible or impossible outcomes.
How are plus-and-minus grades assigned?
The included scale uses common percentage boundaries. Schools may define different letter-grade cutoffs. Custom boundaries support those local differences.
What happens when the lowest quarter drops?
The lower quarter receives zero weight. Its weight moves to the higher quarter. The displayed notes explain the applied change.
How does exam replacement work?
A higher exam can replace the lower quarter. This rule only runs when enabled. Actual replacement policies may use different limits.
Can grades exceed 100%?
Yes, enable grades above 100% first. Then increase the maximum allowed grade. Bonus points may produce higher calculated results.
What is the GPA equivalent?
It is an approximate four-point grade conversion. It does not calculate cumulative GPA. Official GPA policies can differ significantly.
Are exported results official records?
No, exports only summarize entered information. They are useful for planning and discussion. Your institution provides the official final grade.
