I have a decent GPA (3.6) but have taken no classes in Chemistry and advanced Computer Science (can only code python!). The Physics GRE is incredibly intimidating to me and many topics that it covers are not offered at the liberal arts college I attended. I predict a receiving a poor score and am overwhelmed by the possibility that good grades and a passion for Physics is not enough to be accepted let alone succeed in graduate school. Should I try to get a BS first? Any thoughts/advice?
