<p>zrathustra,</p>
<p>You bring up a great point. We could not afford the univ route. My son did all the community college classes through Dif. Equ. and then worked with an online tutor who gave us a great rate. We also had financial help from an outside source. My son was also able to audit 19 units of college physics at two different univ. for free. We feel very fortunate for all the relatively inexpensive opportunities.</p>
<p>Art of Problem Solving, of course, has outstanding courses. They’re not cheap but they’re not as expensive as some online entities such as EPGY.</p>
