How this calculator works (and what NUS doesn't tell you)

This tool computes a weighted raw percentage. It does not predict your letter grade, because NUS letter grades for CS1010 and its variants are bell-curved per cohort. A raw 75% might be an A- in one semester and a B+ in another. Use this calculator to track where you stand and what you need on remaining components, not to predict the final letter.

The "Load CS1010S defaults" button pre-fills the typical CS1010S weights from recent semesters: Coursemology 25%, Midterm 15%, Practical Exam 15%, Final Exam 40%, Participation 5%. Your specific semester's weights may differ — assessment structures change year to year, so always check the module's actual syllabus on Canvas and adjust the Weight % column to match what your tutor announced.

The CS1010E (engineering variant), CS1010J (Java), and other CS1010 variants have different assessment structures. The defaults are CS1010S-specific — if you're in a different variant, clear the rows and enter your own components.

Mark a component as Completed once you have the actual score. Mark it as Upcoming if you haven't taken it yet. The "Running result" only counts Completed components; the "Maximum possible" assumes you score full marks on all Upcoming components.

Your inputs are saved to your browser's local storage so you can come back later. Nothing is sent to a server, nothing is tracked beyond the standard site analytics (which don't see your scores).
