<p>As a parent of one child who has completed an engineering grad degree and another in the midst of a physical science major, I would agree with BigTrees on this one. I would suggest spending the rest of the summer on math skills, and then by fall you can worry about whether it makes sense to go for the engineering degree or look at other majors and choose schools accordingly.</p>
<p>Also, to OP, I think it is important for your son to learn to ask for help.</p>
