# How to Find Needed Final Score to Pass Class

Knowing what you need to score on a final exam can give you peace of mind and help you study effectively, but grading systems can be complicated, and teachers have different formulas for assigning grades. For this reason, it's difficult to guess or estimate what grade you need to pass a class. To be sure which grade you need to aim for, you'll need to calculate your grade yourself.

• Contact information for your teacher
• Calculator, pencil and paper or a spreadsheet program
• Class syllabus and/or grading scale
• All class assignments or list of grades so far

## 22. List All Grades You've Earned to Date

List all of the grades you’ve earned so far, including attendance, homework and participation. If you don’t have this information, get it from your teacher. If your class uses a computer program or website, your grades may be listed there. If you have to guess at some of your grades, guess low to give yourself room for error. For example, if you think you’ve only missed three classes, assume you’ve missed five instead. When you’re aiming for a grade, it’s better to set your sights too high than too low.

## 44. Subtract Your Calculation from the Total Needed to Pass

Subtract this total from the grade you need. Let’s say you need a total grade of 70 to pass the class. This gives you 16.

## 55. Divide by the Percentage of the Final

Divide this number by the percentage the final is worth in your total grade. Convert this percentage to a decimal first. In this example, you would divide 16 by 0.2, giving you an 80. This means you need an 80 on the final to pass the class.

Double check your work. Multiply your final grade goal (80) by the percentage the final is worth (0.2) and add it to the number you got in Step 4. Your result should be the minimum grade you need to pass the class.

## 77. Use an online final grade calculator

Use a free online final grade calculator to calculate what you need on the final exam.

If your teacher uses a points system, the calculations are easier. Simply add up the points you’ve earned so far and subtract them from the total to find out how many you need. Just make sure you understand how the points are assigned. For example, find out how many points you lose for each absence.

If your teacher uses a letter system, she probably assigns a numerical value to each letter and calculates the grades that way. In that case, you must ask your teacher for her formula before calculating your grade.

Understand your teacher’s grading system. The percentage system should work for most classes, but some teachers calculate grades differently and take other factors into account when assigning a final grade.
