Any suggestions. I already picked up a tip to put everything in scientific notation. This really helps, keep the good ideas flowing.

Look at teh EK book for suggestions on how to find things like squareroots, etc (though I have yet to see a question with any difficult math in it).

Do the scientific notation i mentioned earlier

Do some brief brushing up on things like fraction addition/division/multiplication.

Almost all the problems come out with an even answer of sorts (i.e. it will work out that you divide 80 by 8 or something easy like that). If your answer is complex it is probably wrong.

Many answers wont even require calculation because you can pick out the obviosuly wrong answers

It's too time consuming to sit and calculate all numbers exactly, and so rounding is the best way to avoid detailed calculations..

However, rounding can be a bit tricky because it can work against you. When the numbers in the answer choices differ from one another greatly, then I strongly urge you to round. However, there are questions (and I've seen them )where the numbers in the answer choices are very close to one another..In this case, you will have to calculate the answer the best you can..
