Eliminate Before You Calculate!

In this fast paced, video game, text messaged world, the desire for instant gratification has never been greater. I have witnessed many students fall into this speed trap, especially when it comes to answering the Math SAT questions. The need for speed often leads to misread questions, sloppy set ups and silly mistakes.
Before coming up with the answer read the question until it is fully understood. Eliminate the obvious incorrect answers. For example--if the answer calls for a positive slope, eliminate the answers with negative slopes; if the answer must be less than 90 degrees, get rid of all those answers greater than 90 degrees. This method allows you to enjoy more accurate calculations while avoiding the "sucker answers" which are designed to catch the careless speed demons!
