Open calculatorCommon use cases
Computing CGPA from semester GPAs (different universities use different scales — 10-point vs 4-point), converting between percentage and CGPA (the Anna University, Mumbai University, Delhi University formulas all differ), aggregating marks across subjects to predict final grade.
Attendance percentage — most Indian colleges require 75% minimum; the calculator shows how many more classes you can miss while staying above the threshold, or how many more you must attend to reach it.
Frequently asked questions
How do I convert CGPA to percentage?
Formulas vary by university. Anna University: percentage = (CGPA − 0.5) × 10. Mumbai University: percentage = CGPA × 10. VTU: percentage = (CGPA − 0.75) × 10. Delhi University (4-point): percentage = (CGPA − 0.0) × 25. Each university officially publishes its conversion formula; use the one from your specific university's transcript.
What CGPA is considered first class?
Indian university norms: First class = 60% / 6.0 CGPA (10-point scale). First class with distinction = 75% / 7.5 CGPA. Some universities use different cutoffs — Anna University defines first class as 6.5 CGPA, Mumbai as 6.0. Check your university's bylaws.
How does attendance affect eligibility for exams?
Most Indian colleges require 75% minimum attendance to be eligible for end-semester exams. Below 75% but above 65% may permit attendance with medical certificate or condonation. Below 65% is typically a permanent debar from exam. The attendance calculator helps you plan around the threshold.
What's the right age for Class 1 admission?
Most Indian states require the child to be 5-6 years old on the cutoff date (April 1 or June 1). CBSE schools often follow April 1. Some states (Karnataka, Tamil Nadu) have their own cutoffs. The school admission age calculator handles state-specific rules and tells you exact age on admission day.
