Open to advice

<p>Hi all
I began to study SAT last year but gave it up for several months . Yet I have to take it again in next year Jan and May (last chance) to study abroad.
My highest score was 1890. When I return to SAT, I cannot make much progress. I find tremendous difficulty in improving my scores.
Many people here have taken giant leap in SAT. Please give me some advice for me to increase my score so that I can do well in next year tests.
Thank you all
Regards</p>
