What is “Can you use a calculator on the GRE test?”
The question “can you use a calculator on the GRE test?” is a common one among test-takers, and the answer is a definitive yes, but with important caveats. The GRE General Test’s Quantitative Reasoning sections provide an on-screen calculator. This is not a physical calculator you bring yourself, but a basic, four-function calculator integrated directly into the testing software. Understanding its functionality and limitations is crucial for anyone preparing for the GRE.
Who should use it? Every test-taker should be familiar with the on-screen calculator. While it’s tempting to use it for every calculation, strategic use is key. It’s best suited for complex arithmetic that is prone to error when done manually, or for calculations involving large numbers. For simple arithmetic, relying on mental math or quick scratchpad work is often faster and more efficient, saving precious time on the GRE test.
Common misconceptions include believing the calculator is a scientific one (it’s not, it lacks functions like square roots, exponents, or trigonometry), or that it’s a substitute for strong mathematical fundamentals. The GRE test primarily assesses reasoning skills, not just calculation ability. Over-reliance on the calculator can slow you down, as inputting numbers and operations takes time. Furthermore, it’s easy to make input errors, which can lead to incorrect answers. Mastering when and how to use the on-screen calculator is a vital part of your GRE quant strategy.

- Total Quantitative Questions: 40
- Estimated Questions Needing Calculator: 30
- Average Time Per Simple Calculation (Mental Math): 6 seconds (he rarely uses it, so his mental math is slower)
- Average Time Per Complex Calculation (On-Screen Calculator): 25 seconds
- Total Time Allotted for Quantitative Sections: 70 minutes
Outputs:
- Estimated Total Time Using On-Screen Calculator: 30 questions * 25 sec/question = 750 seconds
- Estimated Total Time Using Mental Math: (40 – 30) questions * 6 sec/question = 10 questions * 6 sec/question = 60 seconds
- Estimated Total Time Spent on Calculations: 750 + 60 = 810 seconds
- Estimated Time Remaining for Problem Solving & Review: (70 * 60) – 810 = 4200 – 810 = 3390 seconds (approx. 56.5 minutes)
- Calculator Efficiency Index: (3390 / 4200) * 100 = 80.7%
Interpretation: Mark’s over-reliance on the calculator significantly reduces his time for problem-solving and review. While 56.5 minutes might seem like a lot, it’s nearly 10 minutes less than Sarah’s remaining time, which can be critical on the GRE test. This suggests Mark needs to improve his mental math and be more selective about when to use the on-screen calculator to improve his GRE quant strategy.
