For my post bacc I joined a project that is at a very early stage. We have been doing optimization for a year and most likely publication will be after three years, so not going to have it on time for my applications. My quant GRE is around 163 but my verbal is around 156. As for the LORs, I was thinking to ask my summer research mentors. It has been a while so that is why I am a bit scared they might not be as strong. Thank you for your suggestion about looking on faculty in each school. ☺️
