Nice to hear some advices

Yes, I also did two Kaplan CATs:
3 weeks before the test >> Kaplan CAT: 580 (Q46%, V58%)
2 weeks before the test >> Kaplan CAT: 580 (Q40%, V74%)
I haven't mentioned them because they are supposed to be not the most accurate ones.
Now, I started studying again and that's my roadmap for the next month:
1. Manhattan Number Properties (I want to go through it thoroughly the second time, because I still see Number Properties as one of my major weaknesses)
2. Critical Reasoning Bible Powerscore (Haven't done anything special for CR, except the Kaplan Premier and a lot of people really recommend this book)
3. Manhattan Sentence Correction (I want to go through it thoroughly the second time)
5. Watch Thursdays with Ron
6. Two Manhattan CATs and analyze for certain area of weaknesses (especially in the quant section)
7. Tackle the areas of weaknesses by going once again through the particular chapters in the Manhattan Guides
8. Reset the GMAT Preps CAT Test and do them again
9. GMAT SECOND ATTEMPT !!!
One month to go through these 9 steps, but I'll study on average 2-4 hours a day. (It's anyway not that much time as it was in the month of preparation for the first GMAT attempt)
If the Manhattan CATs and the GMAT Prep CATs are in a range of 650+, I will be ready - hopefully!
I hope this is the right plan :D
Thanks Guys!
