Argggh!!! sat help!

<p>i am SO frustrated!!!! I just retook another CB blue book practice test (the third one) and its been a month... and i still get the same stupid 1600-1800ish score!!! I know that improvment comes in slowly, but i REALLY want to be a semi-finalist for the psat, or at least be commended!!!!! however, the psat is in less than one month!!! I've been memorizing vocab, but on weekdays i've got so much homework, ireally am unable to fit in time to study for the sats, read, etc...I can do about 7 hours on sat-sun... but should i just keep taking practice tests or ahh... what should i do??? does anyone have any good advice to give??<br>
also I'm really unable to concentrate well while i read passages, and just can't get the right anwsers!!!! and I'm basically careless in math... otherwise i could do much better!
please please help, this really means a lot to me!</p>
