- The final button, which is also the biggest button called ‘Transfer Display’ through which calculated answers can be directly sent to the main answer sheet on the computer, in case there is a ‘fill in the blanks’ question.

## Avoiding Full Dependence

Although GRE calculators may be very useful for saving time and effort, full dependence on the calculator could prove counterproductive. For some simple and basic calculations, the use of paper and pencil could still save you more time than the calculator. A look into the questions at first glance, might get you thinking that calculators are absolutely necessary. However, GRE questions are designed to be so! Thus, you have to think carefully before choosing your calculation device – sometimes the device inside your head could help you much better than a calculator.

**Some valuable tips for GRE calculations**

- Do remember some of the following tips to ensure that your calculations during the GRE tests are fast and accurate.
- Balancing your focus on multiple subjects. For example, even though it may look easy, don’t just focus on compound interests. Fixation on special aspects may get you through the easy and medium questions, but will make it difficult in the harder sections.
- Take your time on questions with long sentences. Don’t rush to conclusions, as the answer to that question could be different based on different words.
- Follow the 2 minute per answer rule. In case you know the answers to the current, proceed to the next. Otherwise, spend no more than 2 minutes. However, sometimes it may be worth it to give a difficult question some extra seconds saved from easier ones.
- Observe table and graphs thoroughly. Don’t jump to conclusions. Grasping the data is very important

With the guidance and tips provided, calculate your scores using the GRE calculator is not difficult at all. Just remember though that your GRE scores depend greatly on your effort and knowledge. Good luck!
