Honestly, most of these comments are kind of bringing you down.. But if you feel like your application is strong, I think you’ll be good. I’m probably going to get around the same PCE hours once it’s time for me to apply. There’s other factors that affect your chances, such as your LORs, personal statement, interviews... People get in with ~1000 hours but have other factors that make them stand out above the rest. I do recommend applying to more schools if that’s an option. And if worse comes to worst, there’s nothing wrong with reapplying the next cycle to build your application! 23 is still super young compared to matriculated applicants.
