Im on the same boat as you are. proper review after every practice test is the key i guess.i started at 310 and after 2 tests the score has come to 460 in 2 weeks.Hope would push it higher in weeks to come 
Hang in there. You will make it.
I am also struggling and I know its because of the basics not being right.
I got 350 on the actual test a year ago!! Since then not studied at all, procastination. Now I am and doing well. But a lot is still to be done.
Lets do this.....
