In a realm dominated by Texas Instruments calculators, Casio fx-9750GII

Calculator breaks the monotony. Often touted as the best ‘value for money’ calculator, it delivers the same punch in far less money than the competitors.

Casio FX-9750GII features sleek, thin design flanked by a high-resolution LCD. Though it’s not back-lit, it does the job really well in average lighting conditions. You will only feel the difference if you have been using Texas Instruments calculators for a while – in which case you won’t find it satisfying enough. Display powers seven rows and 21 characters at a time, which is sufficient for most SAT questions.

Processing speed is top-notch since most power is diverted towards calculations and not lighting a high-resolution screen. The average screen ensures that it doesn’t have to power many pixels. Some abbreviations on the menu can be quite inconvenient to read through. The number of applications is limited to 14 and is nothing write home about. Most apps perform simple calculations and graphing jobs excluding CAS (Computer Algebra System).

Main apps include financial functions, lists and tables, matrices, graphing, simultaneous equations, and more. The model lacks exact values and returns square roots and trigonometric values as decimals instead of simplified figures. The programming interface is highly capable in the Casio FX-9750GII. The language and key combinations are basic which users can access quickly through the mini ‘menu.’ Non-Casio users will take time getting used to the abbreviations.

The design is slim and sleek, offering a firm grip. The materials are durable and feature soft-touch plastics. The buttons are arranged logically and have a tactile feel to them. Casio users will recognize the identical menu quickly. It is powered by four AAA batteries, and unfortunately, there’s no rechargeable battery here. You can easily upload apps and data to the PC using a USB port.

If you are looking for an SAT-focused calculator in a budget, simply order Casio FX-9750GII. Read more user reviews on Amazon.
