Hi Sushant.
Indeed, the questions later in a section of the GMAT are just as important as the ones in the beginning. So, you can't game the test by getting early questions correct.

I don't think I can much improve my accuracy. Should I focus on improving my speed to do all 23 questions?
You can certainly improve your accuracy by continuing to learn verbal concept and strategies and practice, both untimed and timed. In fact, the path to greater speed and the path to greater accuracy are both basically the same: develop skill.
Developing your verbal skills will make you both accurate and faster. In fact, to a large extent, the same skills that support accuracy support speed. For instance, if you are skilled in seeing clearly the subtle differences between answer choices that make one incorrect and another correct, you'll also be fast.
So, to score higher on the Verbal section, you can develop your skills by doing the following:
- learning concepts such as parts of arguments, transition words, and question types
- learning strategies such as bringing the main point of a passage into focus using important points and identifying gaps in arguments
- practicing untimed to develop skill and consistency
- speeding up to test pace finding ways to answer questions efficiently and learning to maintain intensity under time pressure
