Okay, so I’m taking the ACT soon, and I’m trying to figure out the best strategies to improve my math score. I’m pretty good with my calculator, so I was hoping to rely on it as much as possible. However, I’ve heard conflicting information about whether or not calculators are allowed on all parts of the math section.
I want to know definitively: can I use my calculator for every single question on the ACT math test? Or are there specific sections or types of problems where calculators aren’t permitted, or maybe even discouraged because they’d slow me down? What are the rules regarding calculator usage precisely? I have a TI-84, will that be allowed? Are there any types of calculators that are banned, and why? And if there are sections where I can’t use a calculator, what should I expect those questions to focus on?
Answer
The ACT permits the use of calculators on the math section, but with specific guidelines and restrictions. It is crucial to understand these rules to avoid any issues on test day.
General Calculator Policy:
The ACT allows calculators on the entire math section. However, not all calculators are permitted.
Permitted Calculators:
- Most graphing calculators are allowed. This includes models from brands like Texas Instruments (TI), Casio, Hewlett-Packard (HP), and Sharp.
- Scientific calculators are permitted.
- Four-function calculators are allowed, but generally not recommended due to their limited functionality.
Prohibited Calculators:
-
Calculators with Computer Algebra System (CAS) functionality are not allowed. Examples of CAS calculators include:
- TI-89 series (TI-89, TI-89 Titanium)
- TI-92 series (TI-92, TI-92 Plus)
- HP 48GII
- Casio ClassPad models
- Any calculator with "Symbolic" manipulation capabilities
- Calculators with QWERTY keyboards (like a computer keyboard) are prohibited.
- Calculators that make noise or require an electrical outlet during the test are not allowed.
- Calculators that can communicate wirelessly with other devices (e.g., Bluetooth, Wi-Fi) are not permitted.
- Cell phone calculators, tablets, laptops, and other mobile computing devices are not permitted.
- Calculators built into other devices (e.g., watches, handheld entertainment devices) are prohibited.
Additional Considerations:
- Responsibility: It is the test-taker’s responsibility to ensure their calculator is permitted. If a prohibited calculator is used, the test administrator may confiscate it, and the test may not be scored.
- Sharing: Sharing calculators during the test is not permitted.
- Memory: It is advisable to clear the calculator’s memory before the test. While not explicitly prohibited, having stored information could raise suspicion.
- Backup: Bring extra batteries for your calculator, as you will not be allowed to borrow batteries during the test. Having a backup calculator is also a good idea, in case your primary calculator malfunctions.
- Calculator Use is Optional: Remember that you are not required to use a calculator on any problem. Some problems are designed to be solved more efficiently without a calculator.
- Test Center Policies: Check the ACT website for any updates or specific instructions regarding calculator use at your test center.
Summary:
You can use a calculator on the entire ACT math section as long as it meets the ACT’s requirements. The most important restriction to remember is the prohibition of CAS calculators. Always check the specific model against the list of prohibited calculators on the ACT website to ensure compliance. If you are unsure whether your calculator is permitted, it is best to err on the side of caution and choose a different calculator that is explicitly allowed.
