What can i do to improve my sat score?

I took the sat in May for the first time and received my scores today, i got a total of 1460 with a 470 in reading, 540 in math, 450 in writing, and a 6 out of 12 on my essay. Im looking to score atleast an 1800+ total, with 600+ in each section. I plan on taking the next sat in october which gives me about 5 months to prep for that, including the summer, and the following one next may. what are my odds of getting my goal score and could i even score alot higher? What could i do everyday to prepare for it, what kind of study plan could i use?
