A lot of multiple choice quizzes and tests might seem simple, but there are a few secrets behind the choices that the test creators make which can help you maximise your marks, even for the questions that are a complete guess!
The questions will often try to throw you off by including other answers that seem right but are just a bit off. Within your four choices this may look like:
1- The inverse of the correct answer (e.g. the negative version, increase instead of decrease)
2- A red herring (the answer that they try and make you think is correct, this could be done with very specific wording that made to confuse you)
3- Factually wrong (the obviously wrong answer you can immediately rule out)
4- The actually correct answer!

Other little tricks to look out for include answers that are too broad/narrow, which may be true but the markers are often just looking for the MOST correct answer. You may also see answers that use familiar or specific terms from the syllabus but applied in the wrong scenarios without answering the question that is asked, as well as the answer that is made to sound fancy as a way to confuse you into thinking it is correct.

By looking out for these strategies that the test makers use, it is easier to rule out answers in an exam. This means that even if you are unsure of the content, you can make an educated guess that has a high likelihood of being the right answer.
