<p>Actually, NEVER choose answers based on what sounds good. In fact, what SOUNDS good is 90% of the time WRONG (yes, i pulled that percentage straight out of my rear end). But seriously, just learn to recognize errors like these. There are only a few grammar concepts you need to know (I estimate about 20 or so). Once you know those, any problem is so easy!</p>
<p>ALSO, I find that what helps me on SAT writing is NEVER UNDERSTAND WHAT YOU READ.
Yes, that sounds super weird, but what I mean by that is just read every word as what it IS, not what it MEANS. Usually, even if I do a complete writing section, I can't recall a single sentence because I didn't focus on the MEANING of the sentence, but rather the sentence STRUCTURE and FORM. The meaning of the sentence is just a distraction; the meaning only needs to be recognized when there are blatantly illogical things going on in the sentence (which are results of incorrect grammar usage- most often misplaced modifiers).</p>
<p>idk if this helps you but it sure worked for me - i got 800 writing consistently on practices and 800 on the real one. This just sort of happened to me unconsciously as I realized what I was doing to get questions right..</p>
