Are those enough?

<p>Hi guys I have studied sat for sevral months and found it extremely hard.
I have no blue book, just get a package of barron’s books( but no Barron’s SAt 2400).
I started at 1400 ( too bad isn’t it?) and aim for 2100 till this october.
what should do?
Do you guys thinks with these books I can fulfil my aim?
thanks you very much</p>
