Few things are more frustrating than losing marks on questions you actually knew. These “silly mistakes” — a missed unit, a misread question, a small calculation slip — add up to a surprising number of lost marks every exam. The good news is that they are very fixable once you know the patterns. Here is how to stop giving away easy marks.
Know the common silly mistakes
- Misreading the question or missing a word like ‘not’ or ‘except’.
- Forgetting units in Science and Maths answers.
- Small calculation or sign errors.
- Leaving questions unanswered by accident, especially on the back of a page.
- Writing the right answer against the wrong question number.
Read the question twice
Many silly mistakes start with careless reading. Read each question at least twice and underline what it is actually asking. This one habit prevents a large share of avoidable errors.
Build simple checking habits
Give yourself small rules and follow them every time: always write the unit, always recheck a calculation, always circle the final answer. These little habits become automatic with practice and quietly protect your marks.
Keep a mistake list while practising
When you practise, note the silly mistakes you tend to make. Seeing your own pattern — say, always forgetting units — makes you far more alert to it in the real exam. Over time, your most common slips simply disappear.
Save time to review
Keep the last ten minutes of the exam to check your paper — units, signs, question numbers and any blanks. A calm final review recovers marks you would otherwise lose to small slips.
Frequently asked questions
Why do I keep making silly mistakes even when I know the topic?
Usually it is speed and carelessness under pressure, not lack of knowledge. Reading questions twice, following small checking rules, and reviewing at the end fixes most of them.
How do I stop losing marks to careless errors?
Track your common slips while practising, build simple habits to counter each, and always leave time to review. Awareness plus small habits make a big difference.
