Which SAT Subject tests to take?

<p>My son has a relatively tough time with the SATs. At this time, he has a 710 in math 2 and 700 in world history. I think he also has a 680 in US History. A few schools ask for three tests so what do you recommend he take and how hard are some of the tests considered?
–bio (he took an intro course at the cc this summer)??
–should he retake Math 2?
–should he take Spanish with or without listening? He took AP Spanish last year.</p>

<p>I guess he’d like to get one more score in the 700s. He is actually very good at math so possibly could increase that score.</p>

<p>Your advice is greatly appreciated.</p>

<p>If it were me I’d retake US.</p>
