I'm being harsh here, but it's my job to tell the truth about careers, not sell you on the idea of a quant career.
I don't care about your verbal GRE, to me that's just a symptom of the dysfunctional US education system, and if you find a way of gaming the system good for you. I do care that you might be choosing a career that won't get you where you want to be.
The work of a quant is mostly beating computers until the damned things do what you want.
On top of that is some maths, and some finance, you will spend much more time with your PC than your girlfriend.
So it's easy to believe that communication skills aren't important.
Easy but wrong.
First, you have to convince some HH like me that you're a viable candidate for a the job I'm trying to fill.
If I can't understand you, then I will assume that the interviewer at the bank won't understand you either.
This is a competitive game, played by smart people from every country on the planet, any weakness will hurt you.
As above I have the luxury of being a native born subject of Her Majesty Queen Elizabeth the Second, by the Grace of God Queen of England, New Zealand, Australia, Canada and Scotland, Defender of the Faith, and Lord of Man.
That means I am right at the centre of the 1,000 dialects of English that populate the world, making it easier for me to understand you than almost anyone else,my job involves talking to people from all nations and some don't even come from places that are recognised countries, so if I don't get what you are saying, no one will.
That's important, since there's a good chance that the person interviewing you may be Russian, French or Italian, and if you add your poor English to theirs, communication may be impossible. Yes it might be their fault, but it is your problem.
Even when you get a job, progress is made by people respecting your contribution, and if you aren't understood, and can't easily understand what people are saying to you, then that can end badly.
Just to emphasise how this crap is critical to your life, any number of hiring managers tell me that they throw away resumes from people who have spelling mistakes in them.
You're lucky that you come from a place where the language is not so very far from English, Chinese people have it harder, and since many of them can do English better than you, I have no sympathy for your position at all.
You need to read books and practice English. I recommend Tom Clancy and JK Rowling for starters, and you might want to invest in the Stephen Fry recordings of Harry Potter to put on your MP3 player all day to help clarify your speech.
