Common IGCSE Student Mistakes — and How Great Teachers Pre-empt Them

The mistakes are predictable — that's the opportunity

Across subjects and sessions, IGCSE students lose marks in remarkably consistent ways: misreading command words, dropping units, showing no working, answering the question they wished was asked, and running out of time on the last questions. Because the mistakes repeat, a trained teacher can systematically pre-empt them — and this is one of the clearest differences students and parents notice between a subject expert and a trained IGCSE teacher.

Five pre-empting habits to build

First, teach command words explicitly and test them. Second, make 'no units, no marks' a classroom law weeks before it becomes an exam law. Third, require written working even for mentally-solvable questions — method marks rescue wrong answers. Fourth, train question-reading: have students underline the command word and the data before touching the answer. Fifth, run timed sections regularly so pacing is a habit, not an exam-day experiment.

The IG Career curriculum dedicates explicit attention to students' common mistakes in each subject track, so you can catch your students' mistakes before they fall into them.
