<p>Are three weeks… NOT IS, ARE</p>
<p>I disagree wth SirWanksalot.Yes, you can improve and reach the 2300+ in three weeks, but it is going to be one hell of a painful journey. Wake up 5 am then study from 6 am to 8 pm,and that way you will improve greatly.</p>
<p>Starting from 2100 is not a good indicator because this means you already know the content and there is nothing to do except practice.</p>
