The exam contains approximately 75 questions to be answered in 90 minutes. ![]() To use the periodic table of elements during the exam, select the Help icon from the menu at the top of the screen and then select the Periodic Table tab. Students will find the online scientific calculator helpful in performing calculations (e.g., arithmetic, exponents, roots, and logarithms). ![]() Visit ETS to learn more and to practice using the scientific calculator. Students are expected to know how and when to make appropriate use of the calculator. Information about how to use the calculator is available in the Help icon under the Calculator tab. To use the calculator during the exam, students need to select the Calculator icon. Scientific CalculatorĪ scientific (nongraphing) calculator, the TI-30XS MultiView™, is integrated into the exam software and available to students during the entire testing time. During this exam, an online scientific calculator function and a periodic table are available as part of the testing software. Understanding of the structure and states of matter, reaction types, equations and stoichiometry, equilibrium, kinetics, thermodynamics, and descriptive and experimental chemistry is required, as is the ability to interpret and apply this material to new and unfamiliar problems. Your calculator can either be your best friend of your most insidious enemy – the choice is yours.The Chemistry exam covers material that is usually taught in a one-year college course in general chemistry. Take the time to investigate what it can do, make sure you are using any new functions or commands correctly, and protect it from damage. Don’t forget that buying the right calculator, and using it when you study for the FE exam has the potential to help you do even better. Your calculator is one of the most important tools you have available to you during the FE exam. If you leave batteries in it for months at a time, the batteries will drain. ![]() Finally, make sure you have fresh batteries for the HP the day of the exam (unless you are using solar models). I once had a friend purchase a brand new calculator right before an exam, only to fail because he wasn’t using it correctly. If you are new to the particular calculator you are going to use, make sure you can perform relatively simple calculations involving things like exponentials, logs, and memory. It would be a shame to use the right function to get the right answer to the wrong problem on the FE exam! Next, try using it with some problems you already know the answer to in order to make sure you are using it correctly. Your first step should be to take a moment to look that function up in your user manual. Let’s say you are going to use an integration function on your calculator. If you decide you want to use a specialized command or function, don’t wait until the night before the test to try it out. Remember: the goal is to figure out how to get the most out of it for the FE exam. It won’t take you very long to skim through the topics to find functions and commands that will help speed up your problem solving. If you don’t have a user manual, don’t worry: you can find them on the web fairly easily. Take some time to get out your user manual and find out what you can do. Most of us barely scratch the surface of what our calculators are capable of, even with the simpler scientific calculators. Remember – every few seconds you save is time you can direct towards the most difficult problems. By practicing this way, you build up both skills and speed, giving you an advantage on exam day. Even a minor typo can cost you precious time. While some problems may be of the “plug and chug” variety, you still have to plug in all those numbers. Knowing the layout of the buttons can save you time and errors in entering formulas. When you are studying for the FE exam, whether it’s working example problems or taking a practice exam, you should always practice with the same calculator your plan to use on the exam. Your first step will be to get one of these calculators well before you take the exam.
