Grade Calculator: limits and things worth knowing

• A weighted grade is the sum of each component's score multiplied by its weight. Weights must total 100% or the result is meaningless.
• Working backwards to a required exam mark often produces an impossible number above 100%, which is genuinely useful information to have early rather than late.
• Institutions differ on rounding — some round 69.5 up to a 70 boundary and others do not. Check the policy before relying on a marginal result.
• Dropped-lowest-score policies and extra credit change the arithmetic and are not modelled by a simple weighted average.

Is it private and secure?

Your privacy is built in. Grade Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
