GMAT Strategy

my first diagnostic was a 340. Few months later 450 and then a 610. I need a 700 but notice that it obviously isnt that easy because of the scoring gradients. Although a general question; what are the traits and steps that are needed to get to the 700 level? THe best thing in my favor is that I am getting trained very well and I am taking advantage of the learning curve because I have a decent grasp on almost all the elements. One thing that helped me alot ws to switch focus to understanding the wrong answers in roder to avoid them. All gmat pros information is welcome.
