How early is it to study for the GMAT?

<p>I am a highschool senior and i want to be fully prepared for the GMAT and such as i want to transfer out of my next year college (rutgers ) into NYU Stern possibly or something?</p>

<p>Can i start studying now and try to teach my self some things or two?</p>

<p>The GMAT score only lasts 5 years, so perhaps you should do it after your sr year, if you intend to go to graduate business school within 5 years of graduation.</p>
