Hi mamu10.
Many people who end up scoring very high on the GMAT start off scoring well below their score goals. So, your experience is not at all unusual. Further, with just a couple of weeks worth of prep, you drove your verbal score up 2 points, your quant score up 7 points, and your total score up 60 points. You made GREAT progress.

Developing the Proper Mindset For GMAT SuccessMeanwhile, to hit your score goal, you just have to keep making similar progress by continuing to prepare effectively.
Generally speaking, the most effective way to prepare for the GMAT is to work topic by topic, mastering one topic at a time by learning key concepts and then doing dozens of topic specific questions until you totally get how to answer questions of that type. You can see how working in this way would drive your score up point by point. Each time you master answering questions of a particular type, your expected score increases.
Regarding increasing your verbal score, as I said, you should work topic by topic, learning to answer verbal questions one type at a time to give yourself the opportunity to learn to answer questions of one type before moving onto the next type. As you work on each type of verbal question, work in the following way.
Go through dozens of verbal questions of that type and learn to CLEARLY and THOROUGHLY define why each wrong answer is wrong and each right answer is right. When I say "thoroughly," I mean go well beyond using gimmicky reasons like "irrelevant," "too extreme," or "awkward." You need to come up with well developed, logical reasons for eliminating or choosing choices.
For example, if you were working on Weaken the Argument questions, you would not simply call answer choices "irrelevant" or "too extreme." You would carefully analyze the relationships between the answer choices and the passages and come up with a more complete reasons for eliminating them, such as, "This choice weakens the wrong conclusion," or "This choice does not attack the relationship between the premises and the conclusion, but rather seems to attack but does not successfully attack one of the premises."
It may take 20 minutes, or more, per question to analyze verbal in this way at first, but being skilled in this type of analysis is the only way to score high in verbal. So, you need to practice analyzing questions in this way, even questions that you have already seen, and take your time, seeking to speed up by developing skill.
Also, to challenge yourself to really see what's going on in verbal questions, see how many you can get right in a row.
It can take a fair amount of work to move a verbal score higher. So, be ready to analyze a lot of questions, do a lot of practicing, and really develop yourself.
At the same time, you can be sure that by carefully analyzing verbal question after verbal question, you will train yourself to see what's going on in the questions, develop your GMAT verbal skills, and drive your verbal score higher.
