     This math strategy is all about remembering how to solve fractions. During an exam sometimes you forget on how to add similar or dissimilar fractions even if you already studied this the night before.
My suggestion is, in adding similar fraction you should memorize, and I mean really memorize that 1/2  + 1/2 =1. During the exam you should quickly solve 1/2 + 1/2 =1   (1 + 1 = 2 then copy the denominator). Now if you come up with the answer 1 then you can use the same procedure to add similar fractions in your exams. Knowing that your solution is correct then you could go on adding similar fractions confidently during your exam. For example, you should use the same procedure you used in answering 1/2 + 1/2 = 1 to solving 1/4 + 1/4 = 1/2. This strategy is applicable only with the assumption that you already learned how to add similar fractions and it just so happen that you became unsure on how to go about it during the exam. Quickly adding  1/2 + 1/2 should equal 1 will only remind you on how to go with the adding of similar fractions.

  

   With dissimilar fractions you should memorize and again really memorize that 1/2 + 1/4 should equal 3/4. So during the exam whatever solution you used to come up with 3/4 then you should use the
same to add dissimilar fraction.  Again this is just a reminder in case you forget a bit. For example if you do not come up with 3/4 as the answer, that would only mean that you should not go on adding dissimilar fractions because you had already forgotten on how to solve it, then you can just concentrate on answering questions that you can answer.

     With Multiplying fractions you should memorize that 1/2 x 1/2 should equal 1/4 (numerators 1 x 1 = 1 and denominators 2 x 2 = 4. Again doing this is like a trial and error 

to make sure that you are really using the correct solution during the exam. Because if during your quick trial and error you do not come up with 1/4 it only means that your solution is wrong and that you
cannot use the same in solving similar problems in your exam. 

      With division of fractions you should memorize, really memorize that 1/2 divided by 1/2 should equal 1. This memorization of answers will only give you the confidence that you're indeed using the correct procedure in answering the questions during your exam. I will not teach you on how to divide or add fractions because I assume that you already studied and learned these.

      With Subtractions you should memorize that 1/2 - 1/2 = 0 for similar fraction and 1/2 - 1/4 should equal 1/4 for dissimilar. You could also memorize answers for mixed fractions that you can use for quick trial and error in your exams.  You can also use this math strategy in other kinds of 

computations like in simple equations, interest and others. You just choose a computation that is easier to memorize.

      I talk about fractions because these kinds of questions are included in IQ tests.  Maybe after about ten years you have already forgotten how to solve fractions and this memorization could help you remember while taking an IQ test
for a job application. 

Trial and Error List

      You don't have to memorize these.  Just try to understand these so you can come up with these on your own. For example if you understand that 1/2 + 1/2 is really equal to 1      or 1/2 + 1/4 is really equal to 3/4 (common sense answers) then you don't 

have to memorize anything at all from these page.

Summary: 

1) 1/2 + 1/2 should equal 1

2) 1/2 + 1/4 should equal 3/4

3) 1/2 - 1/2 should equal 0

4) 1/2 - 1/4 should equal 1/4

5) 1/2 X 1/2 should equal 1/4

6) 1/2 divided by 1/2 should equal 1

Mixed Fractions

1)  1 1/2 + 1/2 should equal 2

2)  1 1/2   + 1/4 should equal 1   3/4

3)   1    1/2 - 1/2 should equal 1

4)   1   1/2 - 1/4 should equal 1 1/4

5)  1 1/2   X   1/2    should equal 3/4

6) 1 1/2 divided by 1/2 should equal 3

Equations

1) Y should equal 1 in Y/2 + 1/2 = 1

2)  Y should equal 1 in Y/2 + 1/4 = 3/4

3)  Y should equal 1 in Y/2 X 1/2 = 1/4

4)  Y should equal 1 in Y/2 divided by 1/2 = 1

      These quick common sense trial and errors list could possibly help you when you're adding or subtracting fractions and you're a bit confused whether to simply copy the denominator or find the LCD first.  Or when you're multiplying or dividing fractions and you're unsure when to reverse fractions. In the future you can make use of a Google Math Trainer Books to practice on. I hope this Google article is helpful to you.....

          When solving Math or number problems you can use that particular educational toy as a scratch paper. I don't know how it is called but it is the one with a square thin transparent plastic or cellophane film on top. It has a pencil made of wood or plastic which is used for writing anything on this film. What is amusing about this toy is that, when you pull the cellophane film up and the other one next to it, all the writings are erased. This way you will no longer consume as much scratch paper as you normally do. You can use this toy repeatedly in solving Math problems and others, making you save money. In the future you can make use of custom made Google Perpetual Scratch Paper you can bring along at school and anywhere you need them. I hope this Google article is helpful to you.....
