sat math help

<p>I'm kinda getting frustrated with sat math. I'm not really accurate with calculations and i have a problem with thinking and analyzing. Each time i finish a section, i leave most questions blank and for questions i don't know while practicing, i always solved them after practice. I really don't want this to affect me in january. i want to know exactly what to do at the right time, how to finish up in time and how to answer all the questions. My last sat, i omitted 24 questions!. i can't go on like this! pls help!!</p>
