Mistakes
- In IB Computer Science, a single misplaced index can cascade into a complete loss of marks on algorithm tracing. Examiners consistently report that top-performing students succeed not because of faster mental processing, but because of rigorous, systematic scratch-pad tracing. Whether you are dealing with a standard loop structure in Paper 1 or a recursive method in Paper 2 Option D, you must document every intermediate state.
