GMAT Strategy

Hi Folks,

I have outlined a 2 months study plan to retake my Gmat exam.
I decided to start with a diagnostic test(Kaplan CD Cat 3) and just scored 460(Q29,V16)
I believe, i can greatly improve in 2 months.
At the moment, my main weakness are:
General:

• Pacing/Timing
  Concentration

Quant:

• Problem Solving(Probability and Combinations)
  Data Sufficiency(All areas)

Verbal:

• Critical Reasoning(Strengthen,Weaken,Assumptions)
  Reading Comprehension(Poor concentration when reading passage,Main idea,Specific details,Inferences)

Study Plan Outline:

• • Use Princeton Review and Kaplan Premier for general strategy
    Practice questions using OG11
    Practice Tests using(Princeton online tests,Kaplan CD Tests,PowerPrep and GMATPrep) every Saturday Morning
    Self Study
  Target Score:740(Q50,V40)
  
  My motivation for studying has really gone down since my last attempt when i scored 500.Your support in working towards my target score will be highly appreciated.
