Math Test Strategies

Here are some tips to help you on your next math exam:

1. Estimate first.
Before you start, try to estimate what you think the answer might be. Even a rough estimate will help you double-check yourself after you arrive at your answer.

2. Translate problems into something you understand.
When you study equations and formulas, put them into words. The words can help you see a variety of applications. For example: c^2=a^2+b^2 can be translated as the square of the hypotenuse of a right triangle is equal to the squares of the other two sides.

3. Perform opposite operations.
If a problem involves multiplication, check your work by division; add, then subtract; factor, then multiply; find the square root, then the square; differentiate, then integrate.

4. Make a picture.
When you are stuck on a complex math or science problem, try to draw an elaborate colored picture or diagram. Sometimes a visual representation will clear your mind and help you figure out a way to solve it.

5. Write down memorized formulas on your test.
Memorize any formulas you think youll need for the exam. Write them all out on your text the moment it gets handed to you. Then you wont need to worry about forgetting them, which will help your anxiety level.

6. Check your work systematically.
Ask yourself if your answer makes sense. Are the units correct? Is your answer consistent with the parameters of the question? Check your formulas.

7. Write each number clearly.
Write your variables clearly so that you dont confuse them with other ones – especially variables that look similar like 4 and 9; 1 and 7; x an y

8. Answer the easy questions first.
Begin answering questions that you know right away. This will build your confidence and help you focus your time and energy on the tough ones later. This is a good way to manage your time as well.

9. Show all your work.
Dont skip any steps when solving math problems. This will help you proof your answers later, and help you avoid any logical mistakes.

10. Organize Your Calculations
Line up your numbers in each step. Use graph paper if it helps. .

11. Finish your test last.
Remain calm and relaxed during your test. Take extra time after youve finished your exam to check all your answers thoroughly. Plan on being the last person in class – and dont worry about others finishing before you.
