If you want to figure out your final grade before it is officially announced, follow the model outline below. It's really simple and doesn't take long to do.

Go through it step-by-step, replacing the subject grades used as examples with your grades.

Right, so how did you get a 'C' in, let's say, Spanish? Here's what you need to calculate your final grade in any class:

- All the grades you have received
- The amount that each grade is worth

So, you make a list of all the grades you have already received. Here's what you find:

- Homework - 94, 87, 92, 85, 83, 89, 79, 91, 83, 90

- Quizzes - 89, 86, 90, 83, 84

- Tests - 81, 87, 78

Next, average the grades within each category to get one grade for each. You do this by adding up all the grades you've received in that subject and then dividing that total by the number of grades (e.g. Homework total 873 / 10 grades = 87.3).

So now you will have:

- Homework - 87.3

- Quizzes - 86.4

- Tests - 82

Your Spanish teacher has told you that homework is worth 25 per cent of your total grade; quizzes are worth 30 per cent; and tests are worth 45 per cent.

The last step to calculating your grade is multiplying each category's grade by the percentage that is assigned to it.

Add these three numbers to get your final grade:

- Homework - 87.3 x .25 = 21.825 (87.3 x 25 per cent)
- Quizzes - 86.4 x .30 = 25.92 (86.4 x 30 per cent)
- Tests - 82 x .45 = 36.9 (82 x 45 per cent)
- Total - 21.825 + 25.92 + 36.9 = 84.645

This gives your final grade, which is 84.645. Most teachers round the final grades, so your rounded grade is 85, which gives you a 'C' in Spanish. That's how easy it is. Good luck!
