You might spend one day on quant and another day on verbal - but within a one-week period, you should be spending time on both (unless you're a very unusual student who only needs to study one section).
You've made good progress on quant so far, but you'll likely make more - as long as you don't try to keep doing only quant all the time. :) Your brain actually works better when it's got some variety, and when you put something down and then come back to it again a few days later... and a week later... and again a few weeks later.
