Please help for upgrading my scores from mid 600s

<p>Hi , I recently gave the SAT and got 600 , 620 and 680 in CR , WR and M respectively.
What I need is anything above 650 and I am appearing for SAT again on Jan 25.
For my previous attempt , I had completed the blue book , kaplan 12 tests barron sat. Now I am doing princeton review and I have just got the Barrons 2400. Please suggest and advice
I’d be more than thankful
P.S. I have also gone through the ultimate sat guide and silverturtle</p>
