<p>I have terrible grammer. I write and speak fine, but I just can’t tell the difference on the test. They all seem right to me.</p>
<p>What grade are you in? Are you still using an English grammar textbook in school? If not, see if you can borrow one, and if you can’t, then I would get a grammar guide like Grammar Smart.</p>

<p>Go through all of the entries, and sections (Abbreviations, Common Errors, Formatting, Parts of Speech, Punctuation, Usage).</p>
<p>Edit: FYI, there are many things that pass in spoken English that are huge no-nos in formal SAT-land, i.e. “Every parent loves his or her child.” instead of “Every parent loves their child.”</p>
<p>for beginners, just read any test prep book’s grammar section if you want a focused review of grammar.</p>
<p>this way you want have to read a whole grammar text.</p>
