Objects and Classes — Class 11 ISC Computer Science revision notes
A 3-page visual revision sheet for Objects and Classes, written for Class 11 ISC Computer Science. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Objects and Classes sheet covers
- A class is a blueprint, an object is a thing built from it
- Fields and methods, the two things a class declares

- Primitive variable
- Reference variable
- The new keyword builds an object
- The this keyword
- Words the question will use
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Computer Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Objects and Classes the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
