My 10 yo boy scored 770 on the SAT math and in the upper 500s on critical reading. He is taking the AOPS Algebra II course and studying trigonometry on ALEKS, in addition to going to IDEA math classes. He is motivated by standardized tests, so I may have him take the SAT Mathematics Level 2 Subject Test when his Algebra II and trig studies are over. Then he should be ready to study calculus.
