OlearnaWASSCE Science: Integrated Science Is Not Your Elective
A student says "I am revising science" and opens whatever notes are on the desk. If they sit Physics, Integrated Science notes will not carry the paper. If they sit Integrated Science as a core, a stack of elective Chemistry will not either.
Write down the paper you sit
Look at your programme. Core and elective are both real, and they are not substitutes. Physics, Chemistry, and Biology each have their own topics. Integrated Science has its own. Practise the one on your registration. When a friend shares a PDF, ask which paper it is before you spend the night on it.
Then pick a topic inside that paper
The same rule as everywhere else: the topic you miss, questions on it, review of the miss, then a fresh question. A general science mood is not a plan.
