How do you calculate what grade you need on your final exam?▼
To calculate the required final exam grade, use the formula: G_needed = (G_target - G_current * (1 - W_final)) / W_final, where G_target is your desired course percentage, G_current is your current weighted average, and W_final is the final exam weight expressed as a decimal. For example, if you hold an 85% current grade, the final exam is worth 20% (0.20), and you want a 90% (A), your needed score is (90 - 85 * 0.80) / 0.20 = (90 - 68) / 0.20 = 22 / 0.20 = 110%, meaning you need 110% (extra credit required) to reach an A, or 60% to maintain a B (80%).
What grade do I need on the final to get an A in the class?▼
The grade needed on the final to earn an A depends directly on your current average and the exam weight. Assuming a standard 90% A- threshold: if you currently have an 88% and the final is worth 20%, you need a 98.0% on the final; if the final is worth 25%, you need a 96.0%; if the final is worth 30%, you need a 94.7%. Conversely, if your current average is 92%, you only need an 82.0% on a 20% final exam to lock in a 90% A- in the course.
What is the difference between weighted grading and total points grading?▼
In a weighted grading system, assignments are divided into percentage categories (e.g., Homework 25%, Midterms 45%, Final Exam 30%), meaning each exam question carries disproportionate weight toward your final semester grade. In a total points system, all assignments contribute to a single pool (e.g., 1,000 total course points), where every individual point carries identical mathematical weight regardless of whether it was earned on a quiz or a final examination.
Can a final exam lower your grade if you fail it?▼
Yes, a final exam can drastically lower your overall course grade. For example, if you enter finals week with a 90.0% (A-) and score a 50.0% (F) on a 25% weighted final exam, your overall grade drops to 90.0 * 0.75 + 50.0 * 0.25 = 67.5 + 12.5 = 80.0%, falling an entire letter grade to a flat B. If you score 0% on a 25% final, your grade drops to 67.5% (D+).
How does a teacher's 0.5% rounding rule affect the score needed on the final?▼
A teacher's 0.5% rounding policy lowers your effective target grade by 0.5% (for instance, treating 89.50% as a 90.00% A), which reduces your required final exam score by 0.5 / W_final. On a 20% weighted exam, this lowers your required score by 2.5 percentage points (0.5 / 0.20 = 2.5%). On a 25% exam, it reduces your required score by 2.0%, and on a 30% exam, it reduces the required score by 1.67%.
Why is my Canvas or Blackboard grade different from my actual syllabus grade?▼
Canvas and Blackboard often display inflated grades because the 'Calculate based only on graded assignments' setting excludes unsubmitted homework, future zeroes, or unweighted extra credit categories from the denominator. Additionally, LMS gradebooks may calculate a pure unweighted points average rather than the weighted category percentages specified in your professor's syllabus, creating discrepancies of 5% to 15% between the portal score and your true academic standing.
