Frequently Asked Questions

Everything you need to know about grade calculations, grading scales, and formulas.

How do I convert my CGPA to Percentage?
CGPA to percentage conversion depends on your university board. For VTU Karnataka, use (CGPA - 0.75) × 10. For CBSE and Delhi University (DU), multiply CGPA by 9.5. For Anna University and standard 10-point scales, multiply CGPA by 10. You can use our instant CGPA to Percentage converter above for exact formulas.
How does the Attendance Bunk Calculator work?
Our Attendance Bunk Calculator computes your current attendance percentage based on lectures attended vs lectures held. It then calculates the exact number of classes you can safely skip without dropping below your target percentage (e.g. 75%), or the number of consecutive lectures you must attend to clear shortage.
What is the difference between Weighted and Unweighted GPA?
Unweighted GPA measures your grades on a standard 4.0 scale regardless of course difficulty (A = 4.0). Weighted GPA awards extra weight for challenging courses such as Honors (+0.5 point) and AP / IB / Dual Enrollment (+1.0 point), allowing your GPA to reach up to 5.0.
How are UK degree classifications calculated?
UK universities assign honours degree classes based on percentage averages: 70%+ is First-Class (1st), 60-69% is Upper Second-Class (2:1), 50-59% is Lower Second-Class (2:2), and 40-49% is Third-Class (3rd). Typically Year 2 counts 20-33% and Year 3 (Final Year) counts 67-80% toward your final result.
