Cramming the night before an exam feels productive, but it's one of the fastest ways to forget what you've studied. Parents often see their child put in long hours, only to be disappointed when the results don't match the effort.
The problem isn't a lack of effort. It's the wrong approach. Cramming doesn't create lasting understanding. Students need steady practice, smart strategies and sometimes extra support to turn stressful nights into confidence on test day.
Why cramming doesn't work
Short-term memory isn't built for long-term recall. Your child might push through a pile of practice questions the night before, but the knowledge fades quickly. Research on the "forgetting curve", going back more than a century, shows we forget much of what we learn within a day unless we come back to it.
Maths makes it worse. Formulas memorised without context don't stick, and maths exams test whether students can apply ideas to new questions, not just recall them.
What works instead
- Spaced practice. Short sessions spread across the week beat one long session. 20 to 30 minutes a day is far more effective than three hours the night before.
- Active recall. Closing the book and attempting questions from memory builds stronger memory than re-reading notes.
- Mixed practice. Working through a mix of question types trains students to recognise which method a question needs, exactly what exams demand.
- Learning from mistakes. Going back over questions they got wrong, and understanding why, is where the biggest gains happen.
How parents can help
Encourage a consistent study routine at a set time each day, and start revision at least a week before the exam rather than the night before. When your child sees the difference steady practice makes, the cram cycle starts to break on its own. Read more about why inconsistent study leads to panic.
