I find this surprising. I taught a two-week hands on boot camp for high school kids in a summer program and they did fine. It was 80 contact hours total. It was a good mix of lecture and labs. I had them taking computers apart, installing software, going through the log files and registry. All of it. And I didn't assign any homework because I had them for two straight weeks, so I didn't feel the need to burden them further during the summer. We covered an 1100 pages in those two weeks.
Generally speaking, High school kids should try for ITF+ before tackling A+. I'd also suggest doing A+ as a two week boot camp offering during the summer. Spreading it over multiple semesters/years runs the risk of a version change before you finish.
