How The Numbers Work
The formulas behind the calculations — for transparency.
Semester GPA Calculation
Calculates the weighted average grade point of a semester, where each grade is weighted by the credit value of its respective course.
Cumulative GPA (CGPA)
Combines performance across multiple semesters. In case credits are not provided, it defaults to a simple average of semester GPAs.
Attendance Target Formula
Estimates the minimum number of consecutive future classes a student must attend to elevate their current attendance to the target threshold.
Safe Absences (Skip Classes) Formula
Estimates how many consecutive classes a student can safely miss before their overall attendance falls below the target threshold.
Questions People Ask
Honest answers about how this works.
Is my grade or attendance data saved?
No. All calculation logic runs inside the client-side JavaScript engine. None of your academic information is sent to servers.
How is CGPA converted to percentage?
Short answer: We support multiple standards. The default formula is CGPA * 9.5 (widely used in CBSE/Indian universities) or a direct CGPA * 10 conversion, which you can toggle dynamically.
