<p>I'm a senior Canadian student with a 3.8/4 gpa, research experience and a few publications from a mid level school.</p>
<p>I was didn't really consider going to an American school until now so haven't taken my GREs. My question is how long does it take to study for GREs? I have a break of about 3 weeks, after my exams until my classes next term start to give assignments.</p>
<p>is that enough? I figure theres no point doing GREs if I don't do well cause it'd be a waste of time and money.</p>
<p>That’s enough. </p>
<p>Just burn through as many practice exams as you can. The math is pretty easy for engineers and you don’t need to go all out for verbal.</p>
<p>I got Kaplan’s flashcards for my ipod touch. It was really convenient to have and I think it did help me on the vocab. (I increased my score 100 points from the 1st practice exam I took to the real thing). </p>
<p>Math isn’t bad, just practice.</p>
<p>Just take timed practice exams until you find yourself settling down on a score. That’s probably the score you’ll get on the real thing, and it’s time to take it.</p>
<p>I’d say at least 3 timed practice tests, spaced a week apart, should be a minimum, and you shouldn’t have to do more than 10. This means you’ll need between 1 and 3 months to practice, taking timed practice tests once per week. The benefit of such light training is that you can reinforce with vocabulary books or writing manuals or a review of high-school algebra.</p>
