Just be careful you don't go too overboard. I applied to 25+ schools last year- received a few interviews and waitlists but no A. This year I was more selective, about 15 schools- received more interviews and multiple A's. I was much more selective and applied to places I wholeheartedly believed I had a shot with, whether that be stat-wise or their stance on IS/OOS applicants. Yes, applying to more schools statistically gives a better chance for matriculation, but just be careful you don't sacrifice quality of essays for quantity of schools. Fingers crossed for you for this cycle, though!
