HI jxav,
Many Test Takers spend 3 months (or more) of consistent study time before they hit their 'peak' scores, so it's likely that you'll continue to improve (and your pacing will get 'better') as you continue to study.
Have you taken any practice CATs that provide you with data about how much time you spent on each individual question? I ask because it would help to know which types of questions you spend the most time on. Once you have that lists, you can then either post those questions in the Forums here or 'Google' them (so that you can see how other members and Experts approach those prompts).
DS questions 'test' a lot of different skills (far more than just 'math' skills), so you might find it beneficial to focus on learning/practicing more strategic ways to approach those prompts.
1) What is your goal score?
2) When are you planning to take the GMAT?
GMAT assassins aren't born, they're made,
