I need help with my Statement of Purpose. I have been doing research on experimental high energy particle physics for the past two years of my undergraduate career. However, I have discovered that there is no way I want to continue work in this field in grad school. In my personal statement, should I say that I want to continue in this field for the sake of continuity and consistency or should I be honest and talk about something that I find interesting but have little training in (Gravity). Little training, in this case, means one class on Differential Geometry and some private study.
