I agree, reading a book… and then reading a book on a different topic when you already had too much of the former… seems like a good approach.
Actually, the school seems to be designed this way, of course only if you assume that 45 minutes is the optimal time to spend with one subject. (Which is probably wrong, and also depends on age, subject, etc. But the idea of “focus on X for nontrivial time, then focus on Y” is there.)
