well, if youve done multiple math destroyer tests and looked over the solutions, youll start to notice that theyre actually testing on the same topics with different wording and setups. so for example, you know theyll almost always have that stupid age question where sally is four years older than joe, who will be twice older than Amy in five years etc.. look at the solutions for those types of questions wherever they come up and try to understand how to solve those types of problems. once you understand it, youll get a feel of how to solve it when it comes up again in the next problem set. its pretty much like this for all the problems, i think. its just a matter of figuring everything out, doing enough problems that it becomes almost second nature, and being able to do problems under 40 seconds. good luck everyone! we'll get through this.
