Click on the "Add Class" button to create a new class section in the calculator. Each class represents a course you're enrolled in.

For each class:

• Class Name: Enter the name of the class (e.g., "Mathematics 101").
• Remove Class: If you wish to remove a class, click the "Remove Class" button.

Each class starts with three empty course/assignment entries. You can:

• Course/Assignment Name: Enter the name of the course component or assignment (e.g., "Homework 1", "Midterm Exam").
• Select Grade: Choose the letter grade you received from the dropdown menu. The calculator will estimate the percentage based on the selected grade.
• Marks (%): Alternatively, you can directly enter the percentage score you received.
• Weight (%): Enter the weight of the assignment towards your final grade (e.g., if the assignment is worth 20% of your final grade, enter 20).
• Remove Assignment: Click the "×" button to remove an assignment entry.

You can add more assignments by clicking the "Add Course/Assignment" button.

After entering all your assignments and their details:

• Click the "Calculate Final Grade" button within the class section.
• The calculator will display your final grade for that class based on the weighted average of your assignments.

Note: Ensure that the total weight of all assignments in a class sums up to 100% for an accurate calculation.

• Weight Sum: Ensure the total weight of all assignments in a class equals 100% for accurate results.
• Grade and Marks Entry: If you select a letter grade, the calculator estimates the percentage. You can adjust the marks (%) if you have the exact score.
• Multiple Classes: You can add multiple classes and calculate grades for each independently.
• Data Entry: Double-check all entered data for accuracy.
• Consult Your Syllabus: Verify assignment weights and grading policies specific to each class.
