<p>I was in a similar situation to you. I got a 1950 on my first SAT in March and was able to increase it by 280 points up to a 2230 on the June examination. Part of my problem was timing and to fix that I did practice tests at a time that was 5 minutes faster than what is actually given on the SAT, i.e. for a Math section which was supposed to be 25 minutes I set my timer for 20 minutes. This was all I did, I think I ended up doing 3 practice tests and it made a big difference. But if you’re shaky on concepts use the blue book to learn them and do the appropriate practice problems.</p>
