Converting IGCSE grades to GPA is often needed for US or other university applications. This guide explains how IGCSE to GPA conversion works and how to use an IGCSE GPA calculator (or gpa calculator igcse), including for Singapore students.

Why convert IGCSE to GPA?

Many universities in the US and elsewhere use a GPA scale (often 0 to 4.0). IGCSE uses letter grades from A* (A star) down to G, so schools and admissions offices often use a conversion table to get an equivalent GPA for comparison. The exact scale can vary by institution; some use unweighted GPA, others weighted (e.g. for honours courses). Singapore students applying to US universities or schools that use GPA may need to provide converted grades or use an IGCSE to GPA calculator to estimate their standing.

How IGCSE to GPA conversion works

Common conversions map the top grade (A* or A) to 4.0, then B to 3.0, C to 2.0, D to 1.0, and so on. Some systems use a weighted GPA or different scales (e.g. 0–5.0). Always check the university or school policy; they may publish their own conversion table or accept IGCSE grades directly. An IGCSE GPA calculator or gpa calculator igcse tool can give an approximate value but is not official; use it as a guide and confirm with the institution you are applying to.

Using an IGCSE GPA calculator

Search for igcse gpa calculator or igcse to gpa calculator online. Enter your IGCSE grades (subject by subject if required) and the tool will give an estimated GPA. Use this as a guide only; confirm with the institution you are applying to. Some calculators ask for the number of subjects and whether to use weighted or unweighted conversion. The result is not an official certificate; it is an estimate to help you and the institution understand your level. Singapore students who are applying to US or other GPA-based systems should also check whether the university wants a transcript or official conversion from their school; some institutions do their own conversion.

When IGCSE grades are enough without conversion

Not all universities require a GPA conversion. Many UK, Australian, and Singapore institutions accept IGCSE grades directly (e.g. A*, A, B) and do not ask for a GPA. If you are applying only to such universities, you may not need an IGCSE to GPA calculator at all. Use the calculator when the application form or university explicitly asks for a GPA or when you are comparing your grades to a GPA-based system.
