Follow the Sequence
Another aspect of the SAT sentence completion section to think about is the sequence of difficulty of the questions. Being able to recognize the pattern can help a test taker be able to better use the process of elimination to get the correct answers - and a higher overall SAT score.
In general, the easier questions will appear first on the SAT, which means you can know which ones will take you less time to answer correctly. Having said that, the easier questions sometimes contain tricky language meant to trip up a test taker moving through them quickly.
Second guessing can sometimes become a big problem when solving these types of problems on the SAT. With similar words as answer choices, it can be easy for a test taker to second guess themselves and end up with the wrong answer even though they know the correct answer. Never underestimate the effect of stress during taking of the test.
For harder questions, sometimes the easy or obvious answer will be wrong because there are better answer choices available. Even so, sometimes the easy word on the harder questions seems like the right way to go. Students need to take special care during both the easy and hard questions on this section of the SAT.
