Just to point out that many of the questions will tell you how many correct answers there are e.g. it will give 5 possible answers and say "select three" - in that scenario there should be no way that you get 3 correct and 1 wrong i.e. you will have selected 4 answers.
This is obviously a big help - as Sherlock Holmes points out "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." - if there are 5 possible answers and you are told to select 3, if you find 2 answers that are definitely wrong then the other 3 are all correct.
