Pattern Elimination Techniques: Rule Out Wrong Answers Quickly
Elimination—ruling out wrong options before choosing—is one of the most powerful techniques in abstract reasoning. Even when you can't fully identify the rule, you can often eliminate 1, 2, or 3 options. That narrows your choice and improves your odds. This article explains how to use elimination effectively.
Why Elimination Works
Wrong options violate the pattern – They have the wrong rotation, wrong count, wrong colour, wrong size. One wrong attribute is enough to eliminate. You don't need to construct the correct answer—you just need to see what's wrong.
Faster than construction – Sometimes building the correct figure from scratch is slow. Eliminating wrong options can be faster. Check each option: does it fit? If not, eliminate.
Reduces pressure – When you're stuck, elimination gives you a path. You're not staring at the question helplessly. You're actively ruling out. That feels more productive and can reduce anxiety.
Improves odds – If you eliminate 2 of 4 options, you have a 50% chance with a guess. If you eliminate 3, you have the answer. Random guessing is 25%. Elimination beats random.
What to Check When Eliminating
Rotation – Is the option rotated correctly? Wrong angle? Wrong direction? Eliminate.
Number – Does the option have the right number of elements? Too many? Too few? Eliminate.
Colour – Is the colour/fill correct? Wrong alternation? Wrong colour in one position? Eliminate.
Size – Is the scale correct? Too big? Too small? Wrong size progression? Eliminate.
Position – Are elements in the right place? Wrong arrangement? Eliminate.
Shape type – Is it the right shape? Circle vs square? Wrong morph? Eliminate.
Symmetry – For "complete the figure" questions, does the option have the right symmetry? Wrong axis? Eliminate.
Combination – If the pattern has 2 rules, an option might satisfy one but not the other. Check both. Eliminate if either fails.
Elimination Process
Step 1: Identify what varies – What changes in the pattern? Rotation? Number? Colour? Focus on those. They're what you'll check in the options.
Step 2: Check each option – Go through options A, B, C, D (or however many). For each, ask: does it violate the pattern? Wrong rotation? Wrong count? If yes, eliminate.
Step 3: Narrow down – How many remain? If 1, that's your answer. If 2, compare them. What's the difference? Which one fits the rule? If 3 or 4, you may need to identify the rule more fully. But you've reduced the set.
Step 4: Choose – From the remaining options, pick the best fit. If you've eliminated well, your choice is informed. If not, guess from the remaining. Still better than random.
Tips for Effective Elimination
Be systematic – Don't jump around. Check rotation for all options. Then number. Then colour. Systematic checking is faster and less error-prone.
One violation is enough – You don't need to find everything wrong with an option. One clear violation (wrong rotation, wrong count) is enough to eliminate. Move on.
Use the pattern – The pattern tells you what to check. If the pattern has rotation, check rotation. If it has number, check number. Let the pattern guide your elimination.
Don't over-eliminate – Be careful not to eliminate the correct answer. If you're unsure whether an option violates the pattern, don't eliminate. Only eliminate when you're confident it's wrong.
Combine with rule identification – Elimination works best when combined with partial rule identification. "The rule is probably rotation. Option A has wrong rotation—eliminate. Option B has correct rotation—keep." Use both.
Practice with abstract reasoning questions and the abstract reasoning test.
Frequently Asked Questions
Should I always use elimination?
Yes. Make it a habit. Even when you think you know the answer, quickly check that the other options are wrong. That confirms your choice and catches errors.
What if I can't eliminate any?
Then you need to identify the rule more fully. Or the options are very similar—look for subtle differences. Elimination works best when options differ clearly on at least one attribute.
Can elimination be faster than finding the rule?
Sometimes. If the rule is complex but wrong options are obviously wrong (e.g. wrong count), elimination can be faster. Use both strategies. They complement each other.
