<p>First of all, did he do well in algebra1 and is he doing well in geometry? For some kids, going too fast gets them into trouble, especially if the foundation in algebra1 was shaky. </p>
<p>Assuming he is finding math fairly easy, you need to look at your school’s curriculum. Most schools have a sequence of algebra1, geometry, algebra2+trig, precalculus, calculus (sometimes in a 2 year sequence of AB followed by BC). Unfortunately, the best way to accelerate your son would have been to take algebra2+trig along with geometry this year. </p>
<p>If I were you, I’d talk to the counselors and see if it’s possible to double up on algebra2+trig with precalculus. This would work better if your school offers semester-based courses (so he can take them consecutively). I would get an opinion how feasible this is from the relevant teachers if the schedule dictates that he would need to take both concurrently. If that won’t work, seems like your only option at this point is a summer school or online course or self-study to cover algebra2-trig this summer or precalculus next summer.</p>
