Mistakes

  • In Paper 1 (Theory Fundamentals), you are up against a strict timer: 90 minutes to secure 75 marks. This translates to exactly 1.2 minutes per mark. High-scoring candidates do not treat this paper as a race of speed, but as a test of scientific precision. Examiners repeatedly penalize candidates who use everyday general terms instead of precise computer science terminology. For example, never call storage 'memory' or data 'information'. When explaining hardware, saying SRAM is simply 'faster' will lose you the mark; you must specify that it has a 'faster access time' compared to DRAM, which requires a continuous physical refreshing mechanism.

Tips are paraphrased for study purposes from exam structure data and marking patterns. Always verify against your official syllabus and mark scheme.
