What next ?

[Sizor]

During the practice tests with GMAT Prep, I am having a verbal score of 33-34.
Although my Quant scores are a bit better at 48. I have been committing 15 errors in both the sections but the scores are diff. Why ?

Out of the first 10 Qs, I have 3 errors in both the sections. However I usually get the first or second Q wrong in the verbal section.
Is it reqd to answer the first 10 Qs correctly for a better score ? (As it is a CAT).
I had faced a difficult RC somewhere around the 20th mark. I answred all 4 Qs based on it wrongly. Does that explain my low scores ?

Any links for tougher Qs in RC, CR and SC.....
