Are there any prerequisite classes that need to be taken in high school before attending Georgetown? For instance, some colleges require 4 years of science (rather than the state requirement of 3 years of science). I’m a junior this year and in my state you are only required to take 3 years of social studies. I didn’t take a history class this year and I don’t want it to count against me in admissions. Will it? Should I take two history classes next year?
