What should I do to get a better score in May?

<p>Hello,
I'm an international student and I did my Jan SAT and got:
Critical Reading: 500
Math: 490
Writing: 530<br>
I know that it's so low but it was my first time and I did 4 practice tests for that test.( Plus I go to a super messed up school where I have daily exams and the passing grade is 80% so I do not really have much time to prepare well for the SAT)</p>

<p>I'm going to take another one in May and I'm aiming for a 1700-1750. Honestly, I will be happy if I got those scores.
So what should I do? What should my 2-3 month plan be like?
I should definitely increase my Math score!!!!</p>

<p>Thank you..</p>
