How to calculate my grades from percentages
Understanding how to calculate your grades from percentages can help you track your academic progress and set achievable goals for success. In this article, we’ll explain the simple steps involved in converting percentage scores into letter grades or a grade point average (GPA).
Step 1: Determine Your Grading Scale
The first step in calculating your grades is to identify the grading scale used by your educational institution. This information can often be found on course syllabi or institutional guidelines. Common grading scales include percentage scales, letter grade scales, and GPA-based scales.
Step 2: Calculate Your Raw Percentage Score
To convert your percentage score into a letter grade or GPA, you first need to calculate your raw score by compiling the results of tests, assignments, quizzes, and any other scored components of your coursework. To do this, follow these steps:
1. List each scored component and their corresponding weights (percentage of the final grade).
2. Multiply the achieved score for each component by their weight.
3. Add up the weighted scores.
4. Divide this sum by the total possible points to get your raw percentage score.
For example, assume a class with four components: a midterm (30%), final exam (40%), an essay (20%), and participation (10%). Suppose you scored 80% on the midterm, 75% on the final exam, 90% on the essay, and 95% on participation:
(80 * 0.3) + (75 * 0.4) + (90 * 0.2) + (95 * 0.1) = 79%
In this case, your raw percentage score would be 79%.
Step 3: Convert Percentage Score into a Letter Grade or GPA
After calculating your raw percentage score, you can now convert it into a letter grade or GPA using up-to-date grading scale provided by your educational institution. Here’s a sample U.S. grading scale for reference:
F: Below 60%
In our example, a raw percentage score of 79% would equate to a letter grade of ‘C’. If you need to convert your letter grade to a GPA, follow the institutional guidelines and use standard GPA conversion scales as follows:
A = 4.0
B = 3.0
C = 2.0
D = 1.0
F = 0.0
Using this scale, a ‘C’ would convert to a GPA of 2.0.
Calculating your grades from percentages is a valuable skill that can help prioritize assignments, set academic goals, and gauge performance throughout the semester. By understanding the grading scale, calculating raw percentage scores, and converting these scores into letter grades or GPAs, you can successfully navigate your academic journey and achieve academic success.
