SLIIT grades each module from A+ (4.0) to E (0.0) and weights every module by its credit value, so a 4-credit module moves your GPA four times as far as a 1-credit one. Enter your modules, credits, and grades below; the GPA and the award class band update as you type. Semester GPA and cumulative GPA use the same arithmetic. The only difference is which modules you include.

Worth knowing: award classes (First, Second Upper, Second Lower) are decided on your cumulative GPA at graduation, and SLIIT's handbook sets rules about repeated modules that a calculator cannot see; the retaken grade is commonly capped. Use this page to track and project; use your student portal for the official number.

SLIIT publishes twelve grades with these mark ranges, and a C is the pass. One thing this page cannot do for you, and it matters more than the grade table: for the 2017 intake onwards SLIIT decides your class on a WEIGHTED GPA, where each year of study counts for a different share and the shares differ by faculty. School of Business and Faculty of Engineering weight the four years 10%, 20%, 30% and 40%. Faculty of Computing weights them 0, 20%, 30% and 50% - a Computing student's first year does not count towards their class at all. This page computes the straight credit-weighted GPA, which is the right number for a transcript average but is not the number SLIIT classes you on. Work out each year's GPA here, then apply your faculty's weights to those four figures.

Questions this calculator gets asked

How is GPA calculated at SLIIT?

By credit value. Each module's grade points (A+ and A at 4.0 down to E at 0.0) are multiplied by its credits; the GPA is total quality points divided by total credits - which is exactly what this calculator computes.

What GPA is a First Class at SLIIT?

A cumulative GPA of 3.70 or above is the commonly published First Class boundary, with Second Upper at 3.30 and Second Lower at 3.00. The current SLIIT student handbook is the authoritative source.

What happens to my GPA if I repeat a module?

SLIIT policy caps the grade achievable on a repeat attempt for most programmes. Enter the grade that will actually appear on your transcript rather than the raw result.

Can I use this for semester GPA and cumulative GPA?

Yes - same formula, different rows. Enter one semester's modules for a semester GPA, or every module to date for your cumulative GPA.

Is my data sent to SLIIT or anyone else?

No. Everything runs locally in your browser. Rows are kept in your own browser's storage so they survive a refresh, and never leave your machine.
