Buying Advice

Before purchasing a calculator, you should consider a couple of things...

Exam Type

You need to know what calculator is accepted by the exam you plan to take. Students who fail to do this often waste hundreds of dollars in test fees and even more for the wrong calculator. Knowing the right calculator saves you a lot of trouble in the long run by giving you a fully functional tool that's exam friendly in the long-run.

Certain exams such as the NCES have a very strict graphing calculator policy. These types of exams allow only certain models of calculator brands to be used during their exam. First find out what calculators are permitted by your exam and dedicate time to learning their operation.

Doing this helps you get acquainted with the calculator and become more prepared for exam time.

Supporting Apps

One thing you'll notice about the TI-84 is the number of apps that can be downloaded by the device. Each of them is beneficial because they are tailored to help you learn whatever math subject you desire. Using apps is an excellent way to understand the full range of possibilities your graphing calculator can offer.

To start, check the catalog of apps that can be downloaded in your calculator. For example, the TI-84 already comes with apps such as Flash Cards, Conic Graphing, and Transformation Graphing. See which apps work the best for you and use them to help you study before exam time.


In conclusion, having the Texas Instruments TI-84 does a lot more than improve your grades. It's a robust tool, meaning that it can be used for years after it has completed its intended tasks, such as school. The TI-84 is a great tool for the long-term because it can create mathematical solutions through high-quality graphs.

To proceed, you'll need to understand how to use your graphing calculator before the exam starts. While it's great to have a high-quality calculator, struggling to understand it during the exam is only going to waste your time and points.

Ultimately, you should study your calculator as much as you are studying for the exam if you want to receive the best results.
