Gmatprep is not representative??

hey everybody,

i gave gmatprep(1st test) 2 days ago and got a 730(50q,38v)..... and i think that the scores reported may not be representative.

while i have encountered contless posts about the accuracy of gmatprep scores, i have also read that gmatprep does not contain repeated questions.......

but in my case, while the quant questions were new, verbal questions were repeated.......
sample this :
out of 11 cr questions, 7 cr were already seen by me(either in OG, or 1000cr or in SETS)......
1 sc was from 1000sc
and 1 rc(4 ques) was from 1000 rc.........

moreover, i think that the algo is also a bit inflated.......... i made 8 mistakes in quant and still managed a 50...... this seems odd to me......

whereas quant is not a major concern, getting repeats in verbal is a concern when i think that GMATPREP is not representative and thus, i dont have anything to benchmark my score........

can anyone pls suggest what should be done in such a situation 2 know where m i standing??
