<p>It looks like your biggest place for improvement is Math, which, luckily, is the easist place to improve.</p>
<p>I find reading the hardest, and it seems like you already improved quite a lot, likewise for writing.</p>
<p>I suggest that you get prep books and focus mostly on math. How many practice tests have you done? You will find (just after doing 3 or 4) that the math section is rather repetitive in the kinds of questions it asks. Get a couple of good math books and (for the most productivity) go through the math section comprehensively and extensively. Read all the sections. Memorize all the formulas. Do all the practice problems. If you just keep this up, I will assure you that your math section will improve greatly.</p>
<p>If you are low on time, then I would suggest, go do a couple of practice math sections first. Then, after checkin right or wrong, find the areas you are constantly missing or weak in. Then, go to the math prep books and target those areas. Or, if you don't have prep books, you can even go to your usual math textbook or ask your math teacher for help. The possibilities are endless!</p>
<p>It seems to me that you can easily raise your math to near 800. Once you have that , you just need to continue memorizing vocab and grammar. If you raise those sections some as well, you are well on your way to 2200 or above!</p>
<p>Oh, and to answer your title question, yes.
Good luck :)</p>
