10 Common Exam Mistakes Students Make — And How to Avoid Them

Exams can be stressful, but more often than not, it's not a lack of knowledge that pulls students down—it's the mistakes they make before, during, and after the exam. The good news? Every single one of these mistakes is avoidable.

Here are the 10 most common exam mistakes students make and exactly how you can steer clear of them.
 

1. Starting Preparation Too Late

The biggest mistake is underestimating how long you will take to revise. Many pupils additionally have behaviours that make them unprepared for their exam. These actions involve many people attempting to stay up later than they should be due to not having enough time to study all of their syllabus material. If you develop a system where you start to revise 3-4 weeks before the exam, break down your syllabus into smaller sections (one section for each day for example), write yourself a plan showing how many sections you will cover, and keep yourself on track, you would not be as unprepared for your exam.
 

2. Studying Without a Plan

Without knowing what you're going to study before actually starting, you may end up studying a lot of the material that you already know and neglecting your weaknesses.

How to Prevent This: Identify weak areas before starting to study. Prioritise the weak areas before the stronger areas; and use your syllabus as a checklist to ensure that everything has been covered and as a guide to completing all topics. Lastly, develop a study goal every time you study.
 

3. Not Practising Previous Year Papers

Many students read their notes over and over but never actually practise answering questions under exam conditions. This leaves them unprepared for the real thing.

How to Avoid It: Solve at least 5–10 previous year question papers before your exam. Time yourself as you do it. This builds speed, improves your understanding of the exam pattern, and reduces surprises on exam day.
 

4. Lack of Attention to Marking Scheme

An example of this could be when students writing long answers for 1 mark questions and short answers for 5 mark questions leading them to waste valuable time and cost them valuable marks.

Avoidance: Always note how many marks a question asks for then use that to measure your answer content based on the number of marks available (i.e., if a question is worth 1 mark, aim for a short/brief reply; if a question is worth more than 1 mark, then use headings, bullet points or lists within the answer).

 

5. Failure to Read the Question Carefully

Many students lose marks due to not taking the time to read the question through before writing their responses. Students have been answering to what they thought was being asked rather than the requirements of what was actually asked.

Avoidance: Always read each question at least 2 times prior to responding; underline/circle the important instruction words (e.g., describe, compare, list, evaluate, or define). These are the key instruction words that dictate what type of answer is required by the student.
 

6. Poor Time Management During the Exam

One of the most frustrating mistakes in examinations is when you run out of time and leave questions unanswered even though you were able to answer them! Here's how to avoid this situation:

When you first get the exam, figure out fairly quickly how many minutes you have for each question and stick to this time frame. If you're stuck on an individual question, move on and come back to it later; don’t waste all of your time on one difficult question!
 

7. You May Gain Bonus Marks by Including Diagrams, Charts and/or Examples in Your Answers

You will be rewarded (i.e., given bonus marks) if you incorporate diagrams and/or examples in your answers to questions in the subjects of Science, Geography, or Economics. Many students do not take advantage of using these items in their responses because they feel this takes too much time.

How to Avoid This: During your studying, practice creating neat, labelled diagrams regularly so that when you are exam-ready, you will have the skills to create a diagram in your exam answer to enhance the reader’s understanding of your answer(s). Whenever possible, include a diagram in your answer. Examiners look for and appreciate the extra effort you put into your answer.
 

8. Writing Messy or Unstructured Answers

If your work contains the right information, an unprofessional appearance or presentation makes it difficult for an examiner to read or evaluate fairly. Many times, poor presentation can negatively impact your final mark for the respective assignment.

To avoid this, make sure to use a clear format for each of your answers: introduction, four or five points of support, and conclusion. For longer answers, consider numbering or using sub-headings. Always remember to leave enough space for the examiner to see your answers clearly and write something about them or take notes next to them. Taking these steps will help give a good first impression of your answer to the examiner.
 

9. Not Using the Revision Process After Studying

A lot of students will study a particular subject once and feel they have fully learned it. The truth is that without revising what you have studied, most, if not all, of that information will be forgotten within a 24- to 48-hour period.

To avoid this, implement the following revision process: after studying a subject, complete the revision process by reviewing the material once on the first day after the initial study and after one week after reviewing it again; then ensure you carry out the final review of all of the same material before the examination; this method is called spaced repetition and has been proven through research to increase the likelihood of long-term memory.
 

10. Letting Anxiety Take Over

Exam anxiety is real; it can even affect the best of us; from forgetting things throughout our studies to making careless mistakes, or panicking halfway through the exam.

What can I do to avoid this? First and foremost you need to look after yourself leading up to the exam: sleep 7 - 8 hours, eat a healthy diet and avoid staying up all night studying! The day of your exam make sure you get to the venue on time; take deep breaths and remind yourself that you have been preparing for this moment! If during your test you become anxious then stop for ten seconds, breathe and bring yourself back in to the present moment.
 

Conclusion

In conclusion; exams don’t only assess your knowledge; they also assess your preparation, strategy and your mind-set. By ensuring that you do not make these ten common mistakes you will give yourself every chance to perform at your best.

Remember that passing exams is a skill and just like every skill you develop with time; you can learn this skill and get better at it.
