Introduction

Are you a student following the Pearson curriculum, preparing for the IGCSE Math program? If so, you’re likely aware that this curriculum permits the usage of calculators for all examinations, both in the higher and foundation tiers. The choice of a scientific calculator is not just a matter of convenience; it’s a crucial factor that can impact your exam performance significantly. In this blog post, we’ll explore the options available to students like you, ensuring you make an informed choice when it comes to selecting the right calculator for your IGCSE math journey.

Which calculators are allowed?

For obvious reasons, the specification neither recommends nor bans specific scientific calculator models. However, there are certain requirements that your calculator must fulfill in order to be eligible for usage in the exam. Based on the tier you have elected your calculator must have the following functions:

• Foundation tier
  • $+, -, \times, \div, x^{2}, \sqrt{x}, \text{memory}, \text{brackets}, x^{y}, x^{\frac{1}{y}}, \bar{x}, \Sigma x, \Sigma fx$ sine, cosine, tangent, and their inverses}.
• Higher tier
  • $+, -, \times, \div, x^{2}, \sqrt{x}, \text{memory}, \text{brackets}, x^{y}, x^{\frac{1}{y}}, \bar{x}, \Sigma x, \Sigma fx$, standard form, sine, cosine, tangent, and their inverses.

Any calculator that meets these requirements will suffice. Here are some of the most widely used calculator models out there.

The most popular brand for scientific calculators is Casio, and you can have a look at some of their calculator models on their official website. Remember that not all calculators listed can be used in the Pearson IGCSE Math exam.

Prohibited Facilities

The specification prohibits calculators with the following facilities :

• databank
• retrieval of text or formulae
• QWERTY keyboards
• built-in symbolic algebraic manipulation
• symbolic differentiation or integration

For most filtering calculators based on the above facilities is quite a hassle. Instead, you should go to the website, and filter using “standard scientific calculator” as shown below.

Another way to check if your calculator is permitted for the exam is to check the calculator specification available on the product page of the official website for each model.

Which is the best calculator?

There isn’t really a name or model that can be mentioned as the best calculator. But it’s more of a personal choice. Ideally, the best calculator should be the one that has all the essential features (which all scientific calculators do). These scientific calculators are designed for scientists and engineers, so they are well and above equipped with the desired features for the IGCSE O/L math exam.

Popular Choice

The Casio FX-991 EX Classwiz and FX-570 EX are both popular choices among IGCSE students. Some of the reasons why they are popular are:

• Numerous video tutorials showcasing these calculators are readily accessible. Opting for popular models offers the advantage of a wealth of available tutorials, making it easier for you to follow along.
• Nearly all English words are displayed on the screen in unabbreviated form. This allows intuition to kick in rather than having to memorize commands.
• Natural Textbook Display – The final answer on the calculator is in a format that can directly be written onto the exam paper.

Cheaper Option

But the EX Series are relatively expensive calculators on the market. For a cheaper option yet with all the essential features, the best value comes with the Fx-991 ES. It also comes up with an approximate battery life of 3 years, which is much superior to the FX-991 EX ClassWiz and the FX-570 EX, which have 2 years of battery life.

Tips for Success

• It’s advisable to stick with the calculator model you’ve been using consistently as the exam date approaches. This is because students often become intimately familiar with the layout, functions, and shortcuts of their calculators over time. Trying to adapt to a new calculator model right before the exam can be challenging and may lead to unnecessary stress.
• Regularly replacing your calculator’s battery, approximately every 2-3 years, is a small but crucial step in your exam preparation. A failing battery during the exam can be a nerve-wracking experience that might affect your performance. By ensuring your calculator has a fresh battery, you eliminate the risk of unexpected disruptions during this critical time.
• A Tool is Only as Good as its User – Learn and practice the functions essential for the exam. There are various YouTube video tutorials that walk you through calculator tips and tricks that are useful for the math exam.

• If you’re planning to pursue higher education in fields like science, economics, or mathematics, it’s worth considering a more advanced calculator model. Investing in the latest model available can ensure that your calculator remains valuable in advanced coursework.

Conclusion

In summary, there are many brands and models for scientific calculators in the market. Amongst them, Casio is highly reputed and used by IGCSE students worldwide. The Casio Fx-991 series is compatible with the IGCSE exam and even for A/level exams. The FX-991 EX ClassWiz is a brilliant option for you, however, if you are looking for a cheaper option you should consider the FX-991 ES model.
