This is the single most important tip. The Edexcel IAL exams have a specific "flavor." They often reuse question structures, and examiners look for specific keywords.

Understand the difference between systematic errors (e.g., a poorly calibrated balance) and random errors (e.g., judging the color change at a titration endpoint). Know how to calculate percentage uncertainty. This is the single most important tip
