Thanks for weighing in Shreeraj. Pinky, please remember to read the forum guidelines before posting. Please don't "bump" your own post. We respond to all posts in order, oldest first, and the date of your post is based on the date of the last post in the thread, not the first. If you bump your own post to a later date, you will wait longer for a response.
Please also note that it is common to wait 3-5 business days for a response on the forums. If you ever have a truly urgent issue, call the office directly.
Now, on to your question. I don't necessarily think that you should give up or that the GMAT isn't for you - I'd like to know more details about your "case." :)
Your scores are fluctuating quite a bit. I don't know which one is the most recent (the one at the top or the one at the bottom?). I can see that your best quant score is paired with your lowest verbal score, though, and vice versa.
Why do you think that your quant dropped on the 660 test? And why do you think that your verbal dropped on the 620 test? If we can figure that out, then we might be able to figure out how to get you to perform at your peak on both sections at once.
The major issues causing score fluctation are typically:
(1) Timing
(2) Holes in your foundation (you know some things well but others not very well at all)
(3) Mental stamina
Read this - which of the above apply in your case?

Then come back here and tell us the results of your CAT analysis and what you think you should do based on that analysis. We'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
