What can I do to increase my Score to 700+?

You should think about a 3 stage program: from 350 to 550, from 550 to 650, and from 650 to 700+You likely need to focus first on content: core math, grammar, and, possibly, academic vocabulary. Whichever way you set this up, and however long you take to do it, you will have a great story to tell. And you yourself will be forever changed.
