Purchase the College Board SAT Practice test book online. Have him take six practice tests under timed conditions every Saturday morning. Then have him grade and review his missed answers on Sunday morning.

One more thing... On the first few practice tests make sure to read the questions for the timed reading passages first. It saves a lot of time. Really time is the enemy.

Sat website lets you take one or two entire tests free. Also get the question of the day sent to his phone. Get as many tests as you can and have him take the tests under similar conditions . 8am quiet timed. Go to college confidential and search xiggi method? Xiggi sat? He gives great advice on how to prep.

You can purchase onlj e prep through college board for under $100

buy him a book and have him do the practice tests to see where he needs the most help. Then have him practice practice practice. No need for a high cost program until he has taken them once to see if he needs it (after a real attempt to do it at home).

DS will be taking the SAT in May and and has not taken any review classes yet. Can you recommend an online class that would be helpful?
Thanks in advance!
