Carnegie Mellon's Summer Programs AP/EA difficulty?

<p>Is the AP/EA Program at CMU difficult to get into?</p>

<p>Would I be able to apply for the SAMS program also, or am I not allowed to apply to two programs at once?</p>

<p>It is somewhat difficult to get into but it is all the more difficult to get good grades. My son took ECE and Programming and found them very difficult. Majority of the students have a good grounding in programming before they take the course. For ECE do not go without BC calculus and good grounding in physics. May be there are some courses that are easier but these 2 and concepts of math are really tough.</p>
