Why do you want to attack the answers this way, “working from wrong to right?” By definition, finding the best answer is a comparison; if you spot a tempting wrong answer, you might not be able to spot what is wrong with it until you've read the right answer. It's most efficient to dump all of the “No way!” answers as fast as you can, and then directly compare the remaining, more tempting answers. Of course, there will always be only one right answer, but your final choice will be made easier if you have already eliminated the bad wrong answers.
