<p>I self studied my way from 1900 to 2300 over the period of 4 months - on and off study about 1-2 hours every week - math was always great so I didn’t work on that, just did past papers occasionally so yeah.</p>
<p>My method was 2 sections of CR and 2 sections of Writing every week for 4 months. It would be different if your struggling in math because then you would have to learn the rules (possibly for writing too, but my foundation was strong in writing).</p>
