With year-end exams already underway for students across the country, many are considering the same studying strategy: stay up later, study for longer, and hope the extra hours translate into better marks. The danger, though, is that studying while exhausted can reduce how much information you retain.
Burning the midnight oil can backfire. According to the Sleep Foundation, too little sleep can cut learning ability by as much as 40%, and it also weakens concentration, memory formation and information processing. Trading rest for extra study hours can leave students with less in their heads, not more.
Preparing for exams is about more than reading the school material provided or practising past papers. A well-designed study environment at home and at school can make a real difference: one that keeps the student calm, makes room for collaboration, and accommodates a variety of study methods, from flashcards and sticky notes to group study sessions.
Here are seven practical tips to help students of every age through exam time:
- Prioritise sleep: Rest supports memory consolidation, while insufficient sleep can undermine concentration and recall. Regular meals, physical activity, and time to relax also help students sustain their effort over the exam period.
- Build a revision timetable around the exam schedule: A realistic plan helps students manage the pressure of several exams being scheduled close together. Work backwards from each exam date, allocating time to the subjects that need attention and identifying topics that are particularly challenging. Splitting study sessions over a few days is generally more manageable than trying to cover everything the night before an exam.
- Break large topics into smaller sections: This makes revision less daunting and gives each session a clear purpose. Rather than having vague intention of studying maths, for example, a student could practise a specific type of equation or work through a set of problems. At the end of the session, they can check whether they have achieved this goal and decide what needs further attention.
- Do ‘active revision’: Rather than simply rereading notes, students should try working through past papers to test how they apply their knowledge under time pressure. Explaining a concept to someone else can reveal whether they genuinely understand it. Flashcards, mind maps and colour-coded checklists are useful ways to test recall and identify gaps.
- Structure each session: Working in blocks of 30 to 45 minutes, followed by a 10-minute break, can help maintain concentration. After three or four sessions, a longer break offers time to recharge. Standing up, stretching, drinking water, or stepping outside provides a useful change of pace, but checking social media can make it harder to return to focused work.
- Seek help when it is needed: A teacher can clarify a difficult concept, address gaps in understanding, or help a student work through a loss of confidence. Asking for support early leaves more time to address a problem before an exam.
- Technology can support the process: Students can use AI tools to generate practice questions from their own notes, then check the answers against their study material. There is a guardrail here: AI should help them test their understanding; it should not replace the work of learning and checking information.
Ultimately, good preparation is about making each study session count. The goal is not to spend every available hour studying, but to use these hours in ways that support learning.
