What are the rules and guidelines for using a calculator on the ACT?

I'll be taking the ACT and I know I can use a calculator for the Math section. What are the specific rules and guidelines for using a calculator on the test, though, to make sure I won't face any issues on test day?

The ACT does allow the use of calculators for the Math section, but there are certain guidelines you need to follow to ensure that you don't face any issues on the test day. Here are the main rules and guidelines:

1. Approved calculators: You must use a permitted calculator for the ACT Math section. Most basic, scientific, and graphing calculators are allowed, but you can check the ACT calculator policy on their official website to find the list of prohibited models, which includes calculators with a QWERTY keyboard or those that require external power.

2. Calculator functionality: The ACT does not permit the use of calculators with built-in computer algebra systems (CAS). However, some calculators with CAS functionality, like the TI-89 Titanium, may be allowed if the CAS functionality can be disabled.

3. Calculator memory: You are allowed to use the stored programs and functions in your calculator, but you must not use any stored documents that contain test material or solutions.

4. No sharing or borrowing: During the test, you are not permitted to share or borrow calculators. Make sure to bring your own calculator, and test it beforehand to make sure it works properly.

5. Backup calculator: It's a good idea to bring a backup calculator, or at least backup batteries, in case your primary calculator breaks or runs out of battery power. However, keep the backup calculator in your bag and not on your desk during the exam.

6. No noise or communication: Your calculator must be silent and must not have communication capabilities, such as Bluetooth or Wi-Fi.

7. No calculator usage during other sections: You can only use a calculator for the Math section of the ACT. It is not allowed during the other sections, including English, Reading, and Science.

8. Test center rules: Make sure to follow the test center's specific rules and guidelines related to calculator usage.

In summary, make sure your calculator is allowed by the ACT, understand its functionalities, and follow the test center's rules to ensure a smooth testing experience. Good luck on your ACT!
