<p>i…didnt really study. and unless you’re an absolute idiot (“what’s an equivalent of 3^-2?” “-9!”), then you dont really need the test prep. my mom made me do the princeton review one, which was a complete waste of time and effort. i doodled the entire time.<br>
i just got out one or two test books the week before and did 2-3 practice tests to get the hang of it and see what kind of stuff they want/are looking for/up to. i got a 2260 in both sittings, which is respectable.
honestly, i think even if you only did one practice test you’d be fine. its not that much studying involved, unless you feel uncomfortable w/ some math techniques or grammar rules.</p>
