I applied to eight schools! So far: Two rejections, one pending rejection (since I wasn't interviewed), one waitlist, three acceptances (thankfully two of them were my top choices), and one pending interview.
My suggestion would be to look into the programs and what their focus is, along with any groups or specializations they offer. If you know what your area of interest is (especially if it coincides with the program or a specific faculty member in their program), speak to that and why your experiences and their program would help you become a successful clinician. I noticed that the programs I was accepted to were the ones where I articulated that the most clearly. Looking back, I would save money and only apply to programs that I truly wanted to attend, rather than letting the anxiety lead to to applying to some schools I wasn't as interested in.
