<p>I got 620 on WR in Jan and i need to improve it to at least 700 in May.Lots of people told me this is completely possible and here i am ,asking for your help 
I have the barron<code>s gruber</code>s and Princeton Review<code>s study guide + the Barron</code>s 2400 book.
I ve exhausted my BB tests without preparing at all (don<code>t judge me),i have some Q and S and want to do some additional practice before doing the tests.
So far i did some exercises from the Barron</code>s study guide and the Barron`s 2400 book ,but i think the problems are unadequate,containing a lot of diction errors that almost never occur on real tests.</p>
<p>From what I’ve heard, Grammatix is the way to go for writing.</p>

<p>I hear Barron’s Writing Workbook or the Writing section of their 2400 book is decent.</p>
<p>I cannot vouch enough for Rocket Review writing. Along with the BB, i went from 550 PSAT to a 730 actual SAT. Just review all the grammar rules in Rocket Review then use the BB to practice</p>
<p>Thank you.I will start with Princeton Review.I already know most of the grammar concepts and only need to practice.Barrons problems seem kind of unadequate …</p>
<p>using the xiggi method i’m constantly getting around 750 on the WR section. i just really studied the writing sections in the CB book</p>
<p>What is this method.Should i read the whole thread ?</p>
<p>from dolcevalse’s post on another thread:</p>

<p>Yep ,I was using similar tactics …
I did all the PR practice tests` with no time limit and analyzed my mistakes.NOw,i am planning to take a full-length prev.admin.test</p>
<p>MG-Hill WR Book is better than Barron’s Workbook.
Actually MG-Hill WR is most similar to the real SAT.</p>
