Hi friends, I am applying for a Masters in Financial Engineering program in November, 2016 at Singapore, which is due to start in June 2017. I have my GRE scheduled for 10/17/2016 (that's two months from now). I would like to focus my GRE prep on the verbal section - especially RC, Text completions and Sentence equivalences. Given that I am a CompSci graduate and have passed my CFA(Chartered Financial Analyst) II with an interest in science and math, I would also like to read passages that I'm uncomfortable with. What are some really good sources that I must read from daily to work on my reading comprehension skill? Also, are there any sites offering more practice passages? Thanks in advance, Quasar.
