Hello, I'm in a very similar situation. I applied to 8 programs, but I was sort of in a hurry for several reasons. I thought about applying to more schools but decided to focus on places where I have a strong fit and would genuinely be happy to attend. I'm international and not entirely sure about my competitiveness, so I'm concentrating my shots on the T50-T30 range.
Regarding the waiting period, I actually believe we'll start hearing back soon. Some programs have already been releasing acceptances or interview invites since last week. I’d say I underestimated how hard it'd be to wait for news, it’s been indeed tormenting. I have to submit my master’s thesis in less than two months, so I’m trying to focus on that while also preparing myself mentally for some rejections.
Anyway, I hope this cycle isn’t too brutal and that we all end up with great offers. Good luck!
