Taking practice tests, going over what you missed and why. Going over tricks. Taking another practice test. Rinse and repeat. My Nephew does this type of tutoring over skype/through a tutoring website. He helped my son jump 4 points, from a 28 to a 32. My son had taken it three times, had moved up 1 point. Then he buckled down and tutored with my Nephew. We got the scores back this morning. Very happy for him.
