How to eliminate wrong answers
Can't see the answer straight away? Cross out the wrong ones!
The big idea
Check one feature at a time and cross out every option that breaks it, until one is left.
Picture it
A guessing game: each question knocks down the faces that don't fit.
Key words
- eliminate
- cross out an option you know is wrong
- feature
- one thing to check: shape, shading, number, turn…
- trap
- an option that's right except for one small detail

The common mistake
The mistake
Pick the first option that looks right.
Instead
Check every option against every rule; traps differ by one small detail.
Why: The wrong options are made from common mistakes, like a mirror image or the wrong count.
Where it comes up in the 11+
GL NVR questions have five options, and the wrong ones are built from common mistakes. Crossing out is faster and safer than guessing.
