Help with GMAT study plan

Hello GMAT peeps,

This is my first post on this forums,

I am currently preparing for my GMAT which is booked on 1-10-2016 and my target score is 720.

I started preparation 2 months ago but right before I study I took GMATPrep test to assess my weakness.

I scored 460 (Q34, V17) I was shocked by the verbal score since I am good at English. Then for a month later I studied from Manhattan foundation books (verbal and Quant) but didn't study from the any Manhattan guide then I took the first MCAT test and scored 550 (Q36, V29). Afterward I started Magoosh course and today I took my second MCAT test and scored 600 (Q43, V31).

I am a bit disappointing with my last score since I have been preparing for 2 months now and in Magoosh predicted score, it shows my score 630-650.

Beside magoosh I also was using OG 16 and did almost 1/3 of it with reasonable correct answers rate ( 80% on average ).

So, Is my progress looks good? because I am having doubts now that I won't be able to reach 720 and was wondering if i could use extra materials in my prep.

My current material are:

Magoosh
OG 16 the 3 books
All Manhattan guides (so far studied a bit from SC one only)
Manhattan Advanced Quant (not started yet)
and lastly CR Bible.

I could really use some feedback on my progress and an advice on how to customize my study plan in light of my current score.
My weak areas so far: SC, Statistics, Some types of word problems and few number properties.

I really appreciate your contributions, thanks in advance
