Must/Always Questions
For these types of questions on the SAT it is important to come up with a strategy that is specific. Whether the question straight out asks for this or infers it, solving this type of question is the same. It is important to not just select an answer and move to the next one. It is necessary to disprove the other answer choices as well. The one that cannot be disproved will be the final answer.
TIP: Be creative and try to break any patterns that may form. For example, if you are given a < b < c < d < e, try 1, 2, 3, 4 and 5 for the numbers then try 1, 2, 344, 3444, and 1,000,000. The point is to disprove options and not to get through the question quickly. Taking time to answer the question correctly will increase the overall math score on the SAT>
