Pro Tips

Understand Grading Scales
Different institutions use different grading scales. Some use a 10-point scale (90-100 = A), while others use a 7-point scale (93-100 = A). Always confirm which scale your school uses.

Track Cumulative Performance
Don't focus solely on individual assignment grades. Calculate your cumulative grade regularly to understand your overall standing and identify areas needing improvement.

Consider Weighted Grades
Remember that many courses weight different assignment types differently. A test might be worth more than homework. Check your syllabus for weight distributions.

Set Realistic Goals
Use the calculator to set achievable grade goals based on remaining assignments. If you need a 98% on the final to get an A, you might want to reassess your target.
