Need to increase sat score

<p>Hey , when I was preparing for my SAT's , I used BB and usually scored 2100-2200 but when I appeared for the real thing , I got 1780. Could anyone please help me with the CR section ? Specially tackling the paragraphs ? THE BEST AND VERIFIED METHOD !
When my analysis came , they showed I did 20 mistakes which lowered my score to 550
I need around 650 in reading , 750 in writing and 800 in maths (i can capitalise my maths)
I know I have the potential cause I scored good in BB.
Currently I am doing KAPLAN 12 tests and Barrons (not 2400)
Please advice</p>
