Precision academic calculators and study utilities designed for students worldwide. Calculate weighted CGPA on any global scale, convert GPA to percentage, boost focus with drift-free Pomodoro intervals, and solve percentages in real time.
Academic Suite
Essential calculators engineered for high school, college, and postgraduate students. Zero accounts, instant results.
Calculate your weighted semester or cumulative GPA across any number of courses with credit weightings on any global grading scale.
Convert your GPA to percentage for graduate admissions, scholarship applications, and job eligibility with authentic institutional formulas.
Master exam revision and beat study fatigue with interval timing, audio alerts, and background tab drift compensation.
Solve 4 distinct percentage equations: find X% of Y, calculate what percent X is of Y, test score percentage change, and find the base number.
Determine your current attendance percentage and calculate how many classes you can safely skip or must attend to satisfy mandatory minimums.
Divide your available study hours proportionally across multiple subjects based on credit weights or exam difficulty ratings.
Calendar-precise age calculation in years, months, and days for competitive exam age cutoffs and scholarship eligibility deadlines.
Instant scientific conversions across 5 core STEM categories: length, mass, temperature (with offset math), volume, and time.
Live text metrics for term papers and assignment submissions, measuring characters, words, sentences, paragraphs, and reading time.
Keep track of critical midterm and final exam deadlines with local countdown clocks sorted by earliest test date.
Engineered for Students
Built to solve real mathematical and institutional challenges students face every semester.
Most online GPA calculators enforce a US 4.0 or Indian 10.0 scale, breaking for students in the UK, Nigeria, Europe, or Australia. We allow you to define any scale ceiling (4.0, 5.0, 7.0, 10.0, or custom) and weight your courses precisely.
Your academic calculations stay strictly on your device. Grades, courses, attendance marks, and exam schedules are processed entirely inside your browser memory. We never store, log, or transmit your academic records to any server.
From floating-point rounding guards and mathematical sign corrections for negative percentage changes, to timestamp-synchronized Pomodoro countdowns that survive background tab throttling, our tools are built for reliability.
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.
If your university does not mandate a specific formula, the standard universal method is the Proportional linear formula: (GPA ÷ Scale Max) × 100. However, many Indian institutions (such as CBSE and certain state universities) officially prescribe multiplying by 9.5 (GPA × 9.5) or using (GPA − 0.75) × 10. Our converter supports both scale-agnostic proportional conversion and opt-in presets for 10-point scale conventions.
Standard JavaScript countdowns that decrement seconds on a basic 1-second interval experience severe clock drift when browsers throttle background tabs to save battery. Our Pomodoro timer records an absolute target timestamp (Date.now() + duration) and continuously derives the remaining time from the real-world clock, ensuring your focus and break sessions remain 100% accurate even in inactive tabs.
No. ScholarKit is built on a strictly client-side static architecture. There is no backend database, no user account system, and no tracking scripts collecting your data. Every calculation, countdown, and text metric runs entirely inside your local browser memory and resets when you leave or reload the tab.
Yes. While presets are provided for common 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 used in French systems or 6.0 in Swiss scales). The calculator dynamically validates and weights all course inputs against your custom ceiling.
