<p>Hello, all.</p>
<p>I am a junior in high school, and I am planning to take SAT next year. However, I am not quite good at writing, but the essay takes up 25% of the Writing Section. </p>
<p>Well, I am planning to write an essay every single day. But I think it may be a good idea to have some textbooks which can give me certain instruction and help me work on my writing style. </p>
<p>Please recommend any textbooks (better be pdf version), that can tutor students how to improve their writing skills.</p>
<p>P.S, I already have the pdf version of The Element of Style. Is it a good book?</p>
