GMAT Strategy

Hii

I had scheduled my CAT for 27th of January ..but due to some reason I couldn't appear for the test
I had started preparing in December and completed almost all the material I had along with MGMAT CATs & GMATPrep I,II
Now I have planned to take the GMAT in next 17 days.I would have loved to take even before that but it's not possible

Now I really don't know
1) what do I study (I have written below the books I studied from)
2) which tests should I take ( I have Kaplan CD.but I don't think those tests are good)

I know there is huge material available for GMAT..But I want to know some good reliable sources
I am scared that I will lose my tempo.
Please guide

P.S :

In MGMAT CATs I scored in the range 670-710 (The scores are slightly inflated since I had come across few problems earlier on forums)
GMATPrep II ( Q50, V 33, 690)
I improved my Verbal from V22 to V33-38..
In quant I always score in the same range (49-50)
