Following are some of the tips to study math effectively:
1. Always read math problems completely before beginning any calculations, which leaves no chance to misunderstand the problem and the figures too.
2.Whenever possible draw a diagram.
3.If you know that your answer to a question is incorrect, and you cannot find your mistake, start over on a clean piece of paper, in order to focus on the question and not on the error.
4.Do not feel that you must use every number in a problem when doing your calculations. Some mathematics problems have "extra" information. These questions are testing your ability to recognize the needed information, as well as your mathematical skills.
5.Be sure that you are working in the same units of measure when performing calculations. If a problem involves inches, feet AND yards, be sure to make the appropriate conversions so that all of your values are in the same unit of measure.
6.Be sure that your answer "makes sense" (or is logical).
7.Remember, that it may be necessary to "solve" for additional information in a problem before being able to arrive at the final answer.
8.If time permits, go back and resolve the more difficult problems on the test on a separate piece of paper. If these "new" answers are the same as your previous answers, chances are good that your solution is correct.
9.Remain confident! Do not get flustered! Focus on what you DO know, not on what you do not know. You know a LOT of math!!
10.When asked to "show work" or "justify your answer", don't be lazy. Write down EVERYTHING about the problem, including the work you did on your calculator. Include diagrams, calculations, equations, and explanations written in complete sentences.
11.If you are "stuck" on a particular problem, go on with the rest of the test. Oftentimes, while solving a new problem, you will get an idea as to how to attack that difficult problem.
12.If you simply cannot determine the answer to a question, make a guess. Think about the problem and the information you know to be true. Make a guess that will be logical based upon the conditions of the problem.
13.In certain problems, you may be able to "guess" at an approximate (or reasonable) answer. After you perform your calculations, see if your final answer is close to your guess.
Hope this helps.
