Question

Students who utilize the "read, underline and eliminate" strategy are more likely to get better test grades. Why is this is so?

Answer 1

Elimination enables students to limit the amount of possibilities they will have to calculate. This gives them more time to calculate other questions and answers.

Answer 2

My english teacher would always tell us "If you're not annotating, then you're not really reading." This is along the same lines. Marking text helps a student better understand what they're reading, and it makes it easier for them to go back and reference the text when needed.
