If I get a 330 on the GRE, does that guarantee me admissions into my dream college?
Not really. A great score on any standardized test, including the GRE, does immensely boost your admissions chances. However, that is not the only criterion that would get you into your dream school. In addition to your test scores, colleges will consider other aspects of your profile, such as your academics, your work experience, your essays and recommendations, while deciding upon your admissions chances.
