For most questions on the LSAT, it’s possible to have some idea of what the correct answer is before peeking at the answer choices.
Taking a little extra time upfront to anticipate what the correct answer will look like will eventually reduce the overall amount of time each question takes.
Correctly anticipating the answer will 1) allow you to select the right answer choice quickly and confidently and 2) reduce the number of times you have to deliberate over more than one answer choice or re-read the question. So practice predicting what the right answer will look like as you do your homework in each of the sections.
LOGICAL REASONING
Form a general sense of what the correct answer is. For example, with Characterization questions, you'll need to identify the conclusion and premises in the argument to properly anticipate. In the Operation family, you'll anticipate the impact of the right answer. In the Implication family, you'll sometimes only anticipate the standard for the right answer.
READING COMPREHENSION
Have a few of the big picture ideas already worked out, like the main point, author’s attitude, and organization of the passage. Those will already form the basis for most of your RC anticipations.
Even if this process takes a lot of time initially, that’s OK! Keep practicing, and eventually, you’ll be able to anticipate more quickly and reliably. The LSAT is a pattern-based test, and over time your anticipations will become more accurate and you'll gain more confidence in them.
