40 V in first mock test. Fluke?

First of all I wanted to thank you guys of the community for putting up quality material and insight and making them available to everyone.

I started my prep on Semptember, 1st and this morning I took my first full length mock test (the GMATPrep one). I scored 680 (44 Q, 40 V) which is a good score for me since my plan is to take the test in the first half of December and my target score is 650 (although a 700+ would be ideal).

The quant raw score is a bit low but I'm not worried about it beacuse most of my mistakes were avoidable and with still a month or so to go I'm confident that I'll be able to improve it.

What worries me is the verbal score. I finished the section with 10 minutes on the clock and I expected a disaster but it turned out that I did very well, especially for a non native speaker like me.
My questions are: is it possible that I encountered a very easy and/or anomalous batch of verbal questions? Is it possible that my score is just a result of luck and therefore I'll probably have a major dropoff in verbal in the next mock test?

I'll take my next mock test (this time one of the Manhattan ones) next week, if my verbal score isn't likely to be a fluke I'll focus exclusively on quant.
