Any school, any country: enter what you have, see where you stand and what you still need. Saved on this device, works offline.

Bands and rules differ between schools, boards and years, and change over time. Treat every number here as an estimate and check with your school before you plan around it.

This grade calculator works out a weighted average and what you need on the final for any school, and the aggregate for these systems: Singapore PSLE Achievement Levels, O-Level L1R5 and ELR2B2 with bonus points, A-Level rank points on the 70-point scale (2026 onwards) and the older 90-point one, polytechnic and university GPA; IB Diploma points out of 45; US GPA, weighted and unweighted; Canadian GPA on 4.0 and 4.33; UK degree classification and GCSE 9-1; an indicative ATAR from scaled scores; CBSE percentage and 10-point CGPA; and ECTS credits. Every number shows the working beside it. How L1R5 and rank points are built is explained in this post.
