How to Do Open-Book Exams Without Wasting Marks

To do open-book exams without wasting marks, treat them like normal exams: learn the material, build clear notes, and use your books to check details, not to write whole answers. Plan your points first, then look up only what you need so you stay within the time and show your own understanding.

When you hear “open-book exam”, it can sound easy. You imagine having all your notes, textbooks and slides in front of you, and think, “I’ll just look everything up on the day.” That’s how a lot of students lose marks.

Open-book exams are not memory tests, but they still check how well you understand the module and how you use ideas in a short amount of time. If you’re not ready, you can spend half the exam searching through notes and copying paragraphs instead of answering the question.

Open-book exams don’t reward the person with the biggest pile of notes. They reward the student who:

  • understands the core ideas

  • can find the right detail quickly

  • plans answers before writing

  • uses books and notes to support their own thinking

If you treat open-book exams as “normal exams with backup”, rather than “open internet time”, you’re far less likely to waste marks – and far more likely to walk away feeling that you showed what you can really do.

This guide walks you through how to use the “open-book” part properly, so you keep control of your time and your marks.
