GRE Writing Prep

<p>Hi, I'm currently self-studying for the GREs and I needed some tips on how to most effectively study for the writing section.</p>

<ol>
<li><p>Are there any good reviews books that detail how to write an effective essay?</p></li>
<li><p>How do I practice the writing sections on my own? It's hard to judge my own writing and look for areas of improvement. I don't have easy access to other people that'd be willing to judge my writing.</p></li>
