GMAT Strategy
Test-Day Reset
Recover from confusion by rechecking the question, relevant information, units, and quickest reliable method.
Reset
When you feel lost, reset the task before doing more work.
Extra calculation is useless if the question, unit, or denominator was misread.
Three checks
Use a three-check reset.
- 01What exactly is being asked?
- 02What information is actually relevant?
- 03What is the quickest reliable method: estimate, eliminate, plug, or calculate?
Unit
Tag the unit mentally.
Percent, dollars, thousands, miles per hour, and per-person values are not interchangeable.
Timeframe
Tag the timeframe.
A correct value from 2024 is still wrong when the question asks about 2023.
Magnitude check
Estimate when two close-looking numbers could trigger a careless error.
A rough expected magnitude can catch a misplaced decimal, wrong denominator, or implausible answer.
Method switch
If a question stalls, change method before adding complexity.
Backsolve from choices, pick numbers, estimate, or eliminate when the structure supports it.
Control
Do not confuse consistency with perfection.
The practical goal is to avoid unforced errors and spend effort where it changes the answer.
Mini application
Try this reset: You have calculated for 45 seconds and none of the choices are close.
What should you check first?
Solution
Re-read what is being asked, then check units and denominator.
A mismatch between your result and every choice is often a setup error, not a signal to do more arithmetic.
Remember this
Question -> relevant data -> quickest method.
Return to that sequence whenever the problem starts to feel noisy.
