Are Gmatclub Verbal tests too hard...!!

Hi fellow GC members,

I am writing this because i am facing a situation very common to non-native speakers - issues with Verbal.

I have gone through various posts and they mostly stress that GC Verbal is not reflective of Official Verbal either in algorithm or in quality. I get the point but having given the tests - 2 six months ago and 1 recently, i have hardly made any progress(rather scored 2 points lesser).

Firstly, for SC I referred to Kaplan Verbal book and then Manhattan guide. Also, I have taken e-gmat course which is about to expire but that seems to have not helped me. May be I am missing the crux here since the course is very vast and covers the Verbal concepts extensively. I feel more confident after going through the whole course(too time consuming as i see) though whenever I take a test I don't see any improvement. I take too much time to get through the questions ultimately the whole section that i am normally left with 7-8 questions to answer in last 10 minutes irrespective of third party test providers, so i finish the section always in a rush.

In the recent GC Verbal test i scored a dismal 22 though nowhere during the test i felt that i am lagging behind(actually i ensured that i don't). However, it seems that i have compromised on the accuracy as I score between 28-30 for tests provided by other parties. I must mention that i got a very hard RC passage(3rd) in the peak of the time(7 Q's in ~12 minutes left) where i just got one correct.

If I do the questions non-timed I get around 70% accuracy in Verbal. It feels very bad that I am so bad in Verbal and it also affecting my Quant for losing confidence.
What should i do..?!!
OR
I should not bother much with GC Verbal tests(I am sure a improvement in GC test would be a good reflection of my overall verbal improvement).

Thanks
