Avoid these traps

Common mistakes on this skill

Solving before naming the task

The SAT often hides the real skill inside familiar wording. Identify the rule, relationship, or question type first.

Choosing an answer that only partly fits

Many wrong answers are close. Check every condition in the question before committing.

Skipping the final check

Reread what the question asks for so you do not answer a nearby but different question.
