By the way, did you get the right answer to the question above? See the conclusion of this guide to check your answer.
Memorize algebra and geometry formulas.
Make a song of them, hypnotize yourself or chant them for 15 minutes a day. We don't care how you do it, just make sure you know the formulas cold. Although all the formulas you'll need will be given in the test booklet, don't rely on them since it will only waste your time flipping back and forth between pages. Plus, memorizing the formulas will help you to understand how to actually use them.
Experiment with different methods for solving problems.
You will encounter some math problems that involve complicated formulas or a number of steps. Sometimes it is easier to work backwards on those problems. To do this, plug the possible answers into the problem and then do the calculations using that number. When you are taking practice tests, figure out if this method works for you. If it is a strategy that you find useful, decide on which kinds of problems it is most effective.
Plug in numbers for variables.
On problems with complicated formulas and a number of variables, it can be faster to plug in actual numbers for each variable than to use formulas to figure out what the variables are. Try each answer from the multiple choice selections. If you are able to solve the problem, then you know which answer to mark on the answer page.
