Common mistakes in exam strategy

5 mistakes learners make with exam strategy, each one named and explained.

All common mistakes

Every mark counts the same, so spend time where marks are still available.

A pattern used instead of a real guess

What it looks like

The same letter is put for every remaining question rather than a considered guess.

Why it happens

It is fast, and it feels like a system.

A worked example

Question. Several questions left with a minute to go

A common answer. put the same letter for all of them

The answer. make a quick sensible guess at each

Why. Even five seconds on a question usually rules one option out.

Put the two side by side

The same letter throughout: pure chance.
One eliminated option: better than chance, on every question.

Ruling out one obviously wrong answer lifts every guess. It takes seconds.

Marks given up that were still available

What it looks like

The advice chosen abandons a question permanently, or crosses out unanswered ones.

Why it happens

Deciding firmly feels like good strategy, and moving on cleanly feels tidier than leaving loose ends.

A worked example

Question. Questions still blank as time runs out

A common answer. cross them all out

The answer. make a sensible guess at each one

Why. A blank scores nothing for certain, and a guess sometimes scores.

Put the two side by side

Blank: zero, guaranteed.
A sensible guess: better than zero.

Never leave a mark you could still have. Guessing costs nothing when there is no penalty.

Not guessing when guessing is free

What it looks like

Blank answers are left because guessing feels risky, even though wrong answers are not penalised.

Why it happens

Guessing feels like cheating or like a wrong answer will count against you, and often it once did.

A worked example

Question. A multiple-choice paper with no penalty for wrong answers

A common answer. leave the blanks to be safe

The answer. guess sensibly at every one

Why. With no penalty there is nothing to be safe from.

Put the two side by side

Penalty marking: a wrong answer costs you.
No penalty: a wrong answer costs nothing at all.

Check the instructions once at the start. If there is no penalty, never leave a blank.

Staying on a question because time is invested

What it looks like

The advice chosen is to keep working on a hard question however long it takes.

Why it happens

Abandoning work already done feels wasteful, and giving up feels like failing.

A worked example

Question. Stuck for two minutes on one question

A common answer. keep going until it is solved

The answer. mark it, move on, and come back if there is time

Why. Every question is worth the same, so two more minutes here costs two easier marks elsewhere.

Put the two side by side

Every mark is worth the same.
Time spent on a hard mark is time taken from an easy one.

The minutes already spent are gone whatever you do. Only the minutes ahead are yours to spend.

Time moved to the wrong activity

What it looks like

Checking earlier answers is started while questions remain unattempted.

Why it happens

Checking feels productive and safe, and unattempted questions feel intimidating.

A worked example

Question. Stuck on a question with several still unattempted

A common answer. stop and check the earlier answers

The answer. move on to the questions not yet attempted

Why. An unattempted question is a mark you certainly do not have; a checked one you probably do.

Put the two side by side

Checking: might rescue a mark you may already have.
Attempting: might win a mark you definitely do not have.

Attempt everything first. Check only with the time left over.

WAJD spots these patterns in your child's answers and names the one behind their wrong answers, instead of just marking them wrong.
