Using Your Own Calculator on the GED Test
You can bring your own calculator to the GED test and use it during the Social Studies test, the Science test, and Section 2 of the Mathematical Reasoning test.
You can use your own calculator provided the following:

It is a TI30XS onscreen calculator.

You place it in a secure locker before beginning the GED test.

You retrieve it and return to your seat within three minutes during a newly introduced break between Sections 1 and 2 of the Mathematical Reasoning test.
You aren’t allowed to use your physical calculator for Section 1 of the Mathematical Reasoning test, which consists of about six to ten questions. After you answer those questions in Section 1, you will be given a threeminute break to retrieve your calculator.
Note that bringing your own calculator is completely optional; if you’d rather, you can continue to use the onscreen embedded calculator throughout these sections.
Here are a few of considerations to keep in mind when deciding whether or not to bring your own calculator:

Is the threeminute dash to retrieve a physical calculator worth the disruption?

Is using a physical calculator a sufficient benefit over the onscreen calculator to make up for the disruption?

Do you know how to use the calculator well enough to make it worth your while?
Happy testtaking!
