GMAT Strategy

My test is scheduled for five weeks from this friday. I have taken a total of 5 practice tests now and still have three weeks left of my course with Manhattan. My tests were as followed:

Ptest before course: 620 - MGMAT CAT 1
Ptest three weeks ago: 660 GMATPREP 1
Ptest two weeks ago: 710 49/39 Knewton
Ptest this past weekend: 660 44/38 MGMAT CAT 2
Ptest this week cause I was bored: 700 44/42 GMATPREP 1 RETAKE

I'm at a loss here. Not sure what happened with my quant score and fundamentally when I do the OG questions and homework with Manhattan I RARELY get ANY wrong. I was worried about my verbal score but my retake on GMATPREP 1 I finished verbal with around 8 minutes left and scored my highest. I think I've began to grasp RC and SC fairly well and leave time to focus on CR. However, really want to know what I should be doing to bump quant. It's stupid Q's that I'm getting caught up on. I don't think it helped me I finished Q section with 24 minutes remaining on my most recent test (700 44/42). Should I just slow the heck down and be a little more methodical?

Thanks
