If you need percent added and grade and you already have grade, weight, grade, weight, grade and weight, this calculator does the substitution for you. It suits a quick check, a homework answer you want to confirm, or any figure you need to sanity test.
What Is the Semester Grade Calculator?
The semester grade calculator turns grade, weight, grade, weight, grade and weight into percent added and grade.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Semester Grade Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with grade set to 10, weight set to 5, grade set to 2, the calculator returns grade of 3, and percent added of 110. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out percent added?
Enter grade, weight, grade, weight, grade and weight. The calculator then works through the relationship and reports percent added and grade.
What does the semester grade actually calculate?
It takes grade, weight, grade, weight, grade and weight and converts them into percent added and grade using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter grade?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
