How Can I Reach My Goal

I have taken the SAT twice. One in November 2016 and one in March 2016.
In November I got 520 in Math and 590 in Reading + Writing.
In March I got 540 in Math and 590 in Reading + Writing.

My goal for the SAT is to get at least 1300.

I will be taking the August 2017 SAT so I have 4 months to study.

How can I increase both my Math and Reading Score?

Any help will be greatly appreciated!

Just practice as much as you can solve tests official real and everything but concentrate mainly on Barron Princeton and college board and solve full length test after finishing it correct and write down your mistakes

I would focus on taking official SAT’s released by the college board (there should be around 7 of them by now,?)
Just solve the sections you find weakest (for me it was reading) and look over the mistakes very carefully and try doing the same test over again after a while. Focus on accuracy before time. I only did this for 3 practice tests and my score rose from a mid 1400 to a low-mid 1500 range.
