This article offers a comprehensive guide on how to calculate grades into percentages. It covers a step-by-step guide, formula approach, professors perspective, technology-based tools, comparative approach, practical advice, and online tutorial videos.

## Step-by-Step Guide

To calculate your grades into percentages, you need to know the weight of each component that contributes to your final grade. These components include assignments, tests, quizzes, and attendance. Assignments, tests, and quizzes may have different weights. For instance, assignments may be worth 30%, tests may be worth 50%, quizzes may be worth 10%, and attendance may be worth 10%.

1. Determine the weight of each component that contributes to your final grade.

2. Find your grade for each component (assignments, tests, quizzes, and attendance)

For example, let’s assume that the weight of assignments is 30%, the weight of tests is 50%, the weight of quizzes is 10%, and attendance is 10%. Suppose your grade for assignments is 80%, your grade for tests is 75%, your grade for quizzes is 90%, and your grade for attendance is 100%.

(80% x 30%) + (75% x 50%) + (90% x 10%) + (100% x 10%) = 24% + 37.5% + 9% + 10% = 80.5%

## Formula Approach

Grade Percentage = (Earned Points / Total Points) x 100%

Earned points refer to the total number of points you have earned in a component, while total points refer to the maximum possible points for that component.

1. Find the weight of each component that contributes to your final grade.

2. Multiply the weight of each component by the total possible points for that component to arrive at the total weighted points.

3. Add the total weighted points to arrive at the total possible weighted points.

4. Divide the earned weighted points (earned points x weight) by the total possible weighted points.

5. Multiply the result from step 4 by 100% to arrive at your final grade percentage.

For example, let’s assume that the weight of assignments is 30%, the weight of tests is 50%, and the weight of quizzes is 20%. Suppose you received 90 points on assignments out of a possible 100, 80 points on tests out of a possible 100, and 70 points on quizzes out of a possible 100.

(90 x 0.30) + (80 x 0.50) + (70 x 0.20) = 27 + 40 + 14 = 81

Total possible weighted points = 30 + 50 + 20 = 100

81/100 = 0.81

Grade Percentage = 0.81 x 100% = 81%

To apply the formula for curved grades, you need to adjust the total possible points by adding a specific amount of points.

For example, suppose your teacher has announced that every student will receive 10 extra points in their final grades. If you earned 90 points on assignments out of 100, add 10 points to the total possible points, making it 110. Calculate your final grade percentage using the adjusted total possible points.

## Professor’s Perspective

Professors evaluate a student’s overall performance when assigning grades. Some of the factors they consider include class participation, quality of work, improvement over the term, and attendance. Most professors set clear expectations and inform students of how their grades will be calculated. They also provide feedback along the way to help students understand where they stand and how they can improve their performance.

In many cases, professors use a rubric to ensure they are grading students consistently. A rubric is a set of guidelines that explain the criteria and how each assignment or test will be graded.

## Technology-Based Tools

Several technology-based tools are available to help students calculate their grades into percentages. These tools enable students to input their grades, weights, and other necessary information to calculate their final grades. Some of the popular tools include GradeGuru, GradeMate, and QuickGrade.

GradeGuru is a free mobile app that helps students keep track of their grades, calculate their final grades, and plan for their academic future. GradeMate is an online tool that enables students to calculate their grades quickly and easily. QuickGrade is a grading tool that provides a quick and easy way to grade papers or assignments.

## Comparative Approach

Different nations follow different weighting systems and grade scales when calculating grades. For instance, the United States uses the GPA system with a maximum grade of A (4.0 on a 4-point scale). In contrast, Japan uses a 10-point scale and India uses a 100-point scale.

It is essential for students to understand how grades are calculated in different countries as it affects their chances of admission to universities abroad.
