Masking hides a choice so you stop rereading it. Use it when a tempting wrong answer keeps pulling your eye. Crossing off without hiding is in the answer eliminator.
Hide, then compare what remains
Four choices make masking cheap: hide two, pick between two. Flagging is in flagging questions. The review screen still lists unanswered items, in the review screen.
Extreme wording in Reading is a usual hide, in the extreme-language trap.
The bottom line
Mask the trap choice. Compare the rest without looking back at it.

Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
