To prevent unauthorized transcription and distribution of the exam questions, calculators with communicating and text editing capabilities have been banned by the National Council of Examiners for Engineering and Surveying (aka NCEES). You may love the reverse Polish notation of your HP calculator; however, you’ll have to get used to one of the calculators NCEES has approved.
You should start using one of these approved calculators at the beginning of your study preparation, so that you are familiar enough with it by the time of the exam. Please note that the list of approved calculators is reviewed annually. All of the articles we pulled information from for this post are listed at the bottom of this article.
