I think it depends on the curriculum. The last few chapters of my son's Geometry class included beginning Trig, and the last few chapters of Algebra II. I would want to get through most of Geometry before really starting Trig.

If this online school does this all the time, it might be quite workable. Is there a particular reason for doing both together? Does you son really like math?
