## Tips for Success

Navigating the challenges of the GED Mathematical Reasoning test can be made significantly smoother with the right strategies. Below, we dive deeper into four pivotal tips that can pave the way to your success.

### Practice Regularly

It’s often said that practice makes perfect, and when it comes to mathematics, this adage holds true.

Consistency is Key: Regular practice ensures that mathematical concepts remain fresh in your mind. Set aside dedicated time each day or several days a week for GED math preparation.

Diverse Resources: Utilizing a variety of resources can expose you to a wide range of question types. Apart from traditional preparation books, many online platforms offer GED practice tests, study guides, and video lessons tailored for the GED.

Simulated Testing: Periodically, take full-length, timed practice tests to simulate the test environment. This not only helps gauge your preparation level but also builds stamina.

Review Math Formulas You will be provided with a math formula sheet during the exam, so there’s no need to spend time memorizing formulas for test day. However, it’s a good idea to familiarize yourself with these formulas beforehand, ensuring you know how and when to apply them efficiently during the test.

### Understand the Concepts

A superficial approach might help in the short term, but for lasting success, you need depth in your understanding.

• Beyond Memorization: While it’s essential to remember formulas and certain properties, strive to understand why they work. This deeper understanding can help you tackle unfamiliar problems.

• Ask ‘Why’: When studying a concept, always ask yourself ‘why’ it’s true. Engage with the material by questioning and reasoning.

• Discuss and Teach: Talking about what you’ve learned or trying to teach it to someone else can further solidify your understanding.

### Use a Calculator Efficiently

A calculator is a tool, and like any tool, its efficacy depends on the user.

• Know Your Calculator: Spend time exploring the specific functions and shortcuts of the TI-30XS, which is the only approved calculator model for the GED. Familiarity can significantly speed up your calculations during the test and help reduce your overall stress level. While you are allowed to bring your own calculator to the testing center, don’t fret if you don’t have one — you will be given access to an onscreen calculator if needed.

• Practice with It: When solving practice problems, always use the same calculator model that you’ll use on the test day. This helps build muscle memory and efficiency.

• Limit Dependency: While a calculator is useful, it’s essential not to become overly reliant on it. Ensure you have strong mental math skills for simpler calculations to save time.
