I was wondering about doing grad school after my bachelors, but I was wondering how that works. Do most people put their professional life while doing it? I was thinking of teaching HS(High school) throughout my time as a graduate student, but it seems pretty overwhelming having a job AND being a student at the same time. How would balancing a life as a teacher and taking classes and doing some research as a grad student go? Am I supposed to take classes only in the summer?
