Engineered for Students
Built to solve real mathematical and institutional challenges students face every semester.
Most online GPA calculators enforce a single regional scale. ScholarKit provides common grading presets (4.0, 5.0, 7.0, 10.0) alongside configurable custom scale ceilings so you can match your program's specific credit structure.
Your academic inputs stay strictly on your device. Grades, courses, attendance marks, and exam schedules are processed locally in your browser memory. Your calculator inputs are never transmitted to our servers for calculation.
From floating-point rounding guards and mathematical sign corrections for percentage change, to timestamp-derived Pomodoro countdowns that survive background tab throttling, our tools are built for dependable calculations.
Knowledge Base
Answers to common questions about grading systems, conversion formulas, and privacy.
A simple average treats every course equally regardless of instructional hours. In contrast, weighted CGPA multiplies each course grade point by its assigned credit units, sums the total quality points, and divides by total earned credits. This ensures that an intensive 4-credit course has double the influence on your final GPA compared to a 2-credit elective.
Unless your institution specifies an official formula, a common reference method is mathematical proportional normalization: (GPA ÷ Scale Max) × 100. This provides a mathematical scale rescaling, not an official institutional equivalency. Certain educational boards and universities specify distinct formulas, such as the commonly referenced 9.5 multiplier for CBSE or offset formulas like (CGPA − 0.75) × 10 in specific university regulations. Always verify your institution’s official conversion rules.
Standard JavaScript countdowns that decrement elapsed seconds using basic intervals can lag when browsers throttle inactive tabs to save battery. Our Pomodoro timer records an absolute target timestamp (const endTime = Date.now() + duration) and derives remaining duration directly from the real-world clock (endTime - Date.now()), maintaining reliable timing when returning to the tab.
No. ScholarKit processes calculator inputs locally in your browser memory. Calculator inputs, course marks, attendance numbers, and draft text are processed on your device and are not sent to our servers for calculation. Standard website delivery and privacy-conscious analytics operate separately as detailed in our Privacy Policy.
Yes. In addition to presets commonly encountered across various institutions (such as 4.0, 5.0, 7.0, and 10.0 systems), you can select "Custom scale" and input any positive maximum grade point (such as 20.0 or 6.0). The calculator dynamically validates and weights all course inputs against your custom ceiling.
