Hard to tell. I've read alot of the posts on this board and I've come to conclude that using quick fix is the best option for pre employment tests. It costs 30 to 40 dollars and is fool proof. I used it to pass pre-employment test on a job that i didn't want just to make sure it worked.

You could pick some home tests and practice the dullition method and see if that works.

There is alot of good info on this message board, you just need to read it over and determine what works best for you.
