How Final Exam Weight Works

Final exams are typically weighted as a percentage of your total grade. Common weights include:

10% of total grade
15% of total grade
20% of total grade
25% of total grade

The higher the weight, the more impact your final exam has on your overall grade.

The Formula: What Grade Do I Need?

The formula to calculate what you need on your final exam is:

Required Final Exam Score = (Desired Grade - (Current Grade × (1 - Final Weight))) / Final Weight

Don't worry - our calculator does this automatically!

Step-by-Step: Using Our Final Grade Calculator

Method 1: Online Calculator

1. Visit our Final Grade Calculator 2. Enter your current grade (as a percentage) 3. Enter your desired final grade (what you want to end with) 4. Enter the final exam weight (what percentage of your grade the final is worth) 5. Click calculate to see exactly what score you need

Method 2: PowerSchool Extension

If you use PowerSchool, our extension can calculate this automatically: 1. Install the PowerSchool Grade Calculator Extension 2. Go to your PowerSchool grades page 3. The extension shows what you need on your final exam automatically

Real-World Example

Let's say:

Your current grade: 85%
Desired final grade: 90%
Final exam weight: 20%

Calculation: Required Final Score = (90 - (85 × 0.8)) / 0.2 Required Final Score = (90 - 68) / 0.2 Required Final Score = 22 / 0.2 Required Final Score = 110%

Wait, 110%? That's impossible! This means you cannot achieve a 90% with your current grade. You'd need to improve your current grade first, or lower your expectations.

Let's try a more realistic scenario:

Current grade: 88%
Desired final grade: 90%
Final exam weight: 20%

Required Final Score = (90 - (88 × 0.8)) / 0.2 = 98%

Much more achievable!

What If I Can't Reach My Goal?

If the calculator shows you need an impossible score (over 100%), you have options:

1. Improve your current grade: Focus on upcoming assignments to raise your current average 2. Adjust your goal: Aim for a slightly lower but still good grade 3. Maximize your final exam: Study hard and get the highest score possible

Tips for Final Exam Success

Common Questions

What if my final is worth different amounts for different categories?

Our calculator works with overall final exam weight. If your school uses category-based weighting, use our Grade Calculator instead.

Can I use this for midterms too?

Absolutely! Just enter the midterm weight instead of final exam weight.

Does this work for weighted grading systems?

Yes! Our calculator works for both weighted and unweighted systems. Just make sure you're using the correct current grade percentage.
