                                         practical sense. Hence yields better decisions and better

Here, You could divide 50 by 10 to figure out the answer or either think
of what number should be multiplied to 10 in order to get 50.
In this problem you can immediately notice that option (B) certainly
cannot be the answer, any way the quicker way many be the count on
tens in options as each dot represents 10 and conveniently end up at
option (D) for 50.
Similarly, in a lot of these cases, you can eliminate at least one of the
choices  there can be many variants that you could identify by just
looking at the question. Ask yourself some questions like Can the
answer be an odd number ? Of course, each such question you ask
yourself must pertain to the given question.
Sometimes, a question may seem hard on a quick glance, but if you
read it once more slowly, you can probably see past the apparent
complexity and into a simple solution.
Simple, and more satisfying to do it this way, isnt it ?
So you should always keep in mind that no matter how hard the
question appears, it is very likely that you have already been taught the
tricks for solving it. There may be a few questions that may use
concepts you havent been taught yet (to identify the really advanced
students), but theres not much you can do about that. For a majority
of the questions though, you already know all the techniques you need
to solve them. Its just a question of identifying the right need and
applying the right technique.
You should also know your strengths and use them appropriately. For
instance, you may be very good with spatial questions and at visual
data  then go for the geometry or figure-related questions first. If
numbers dance in your head, go for the arithmetic questions. Get
them out of the way, and then move on to other sections.
Remember : As mentioned earlier, once you have found a solution,
double check that your solution is absolutely right and thats what is
asked in the question.
I trust, equipped with these few tips, you will be able to get over with
any exam. with confidence and ease. Good luck ! !
