Is it true that an SAT score increase of 450+ will...?

<p>patels11, that’s amazing! My timed diagnostic was about 1800, without any studying or any idea what was on the SAT. How can I improve my score as much as you did! Any tips? Or is there a special course you took? Or did you just do practice tests after practice tests until your hand was sore :smiley: thanks!!</p>
