Obtain a GED review book. Browsing the Internet is a good way to start your investigation, but is no substitute for actually looking at the real types of problems you will encounter. Fortunately, examples are readily available. Bookstores and libraries stock huge volumes of GED test preparation books. These extensive books include everything you need to know, including sample tests, concept review, test strategies, on line resources, and general test information.
Browse several books, but don't split hairs trying to decide which book is more accurate. In the test preparation industry, Kaplan, Princeton Review, Barron's and College Board are widely known to be the most authoritative. The best book, though, is the one that works for you.
Assess your readiness. Flip through the books to find out where you stand. Do not be intimidated by the size of these books. They are written in easy-to-understand language, and you don't have to completely master all of the material. You must only pass the exam to receive the GED certificate. Beyond that, your score does not really matter.
If you find you just need a brush up, then spend a few hours working some of the problems and reviewing concepts. If you find the math intimidating, then purchase one of the books. Set a study schedule and work practice tests until you feel more comfortable.
Determine if you need to hire a tutor or take a review course. Most people find that a simple review works well. But if you have difficulty with some concepts, many community centers offer GED courses. If that is out of your budget, considering having a friend or family member work with you.
If you do not pass a portion of the exam, most states specify that you must only retake that portion to receive your GED.
Understand the calculator you will be using. Part I allows the use of a calculator, and the testing center will supply the Casio FX-260. This is a standard scientific calculator, but if you have never used one, you may find it useful to practice on one. They are widely obtainable, and can also be purchased for $8.95 by calling ACE at 800-531-5015. However, on test day, you may only use the supplied calculator.
Review number operations and number sense. You will need to know how to manipulate whole numbers, decimals, fractions, integers. You must use ratio, proportions and percents. You will set up addition, subtraction or multiplication math problems in a column format. You will use the order of operations to solve problems involving parenthesis. You will also use long division, work with exponents, and calculate square roots on a calculator.
It will present word problems where you must create addition, subtraction, multiplication or division problems. You must know how to convert numbers back and forth from decimal, percent and fraction, and be familiar with scientific notation.
Understand basic geometry.If you cannot offhand remember the formula for finding the area of a triangle, don't fret. The GED math test comes with a full page of formulas. The trick, is of course, knowing how and when to use the formulas. You must figure the perimeter, area and volume of figures including angles, triangle, quadrilaterals, circles, cubes and spheres. No proofs are included in the GED.
Review data analysis, statistics and probability.Much of the GED in general includes interpreting graphs and charts. You will be presented with tables, bar graphs, line graphs and pie charts. You must know how to calculate the mean, mode, and median. You may need to know probability and ratios.
Know your algebra. For some, this may be the hardest portion. No advanced algebra like logs or advanced graphic are included. You must work with positive and negative numbers, add and subtract with variables and exponents, and work with parentheses. You must also solve quadratic equations, multiply binomials, and do basic graphing.
Use an easy geometry trick. GED geometry figures are drawn roughly to scale. For example, if need to know the measure of line BC and it says AB is ten feet, you may use a piece of paper and pencil marks to measure the two lines. If they appear equal, then they are and you may skip the calculations. This trick only works on lines within the same problem though.
Leave no question blank. You receive points for correct answers, and are not penalized for incorrect answers. A random guess is better than a blank question, because at least you have a possibility of getting it correct.
Work the entire test first and answer only the easy questions. Afterward, go back and work the more complicated ones. You may remember how to solve the more difficult questions as your mind warms up. This handy strategy helps also if you run out of time. You will have answered all of the easy questions, ensuring their credit, and you may fill in random guesses for the hard ones that you won't have time to answer.
Use the process of elimination. Most of the math questions are multiple choice, and many of the choices are wildly illogical answers. Unlike many standardized tests, the GED does not aim to trick or confuse anyone. Once you eliminate the obviously incorrect choices, you may only be only choosing between two options.
