For RC, read to get the idea and to note where details lie. Then go back to the passages as necessary to make sure that the answer choice you choose actually matches what the passage says.
For some good RC questions, which really challenge you to be careful to match your choice with what the passage says, see the Veritas Question Bank,
https://www.veritasprep.com/gmat-question-bank/.
For CR, probably you are being too cute with the way you are handling the questions rather than using logic as the foundation of everything you do. Be sure to see exactly what the prompts are saying and note exactly what the main conclusion is.
As you work on CR questions, do them slowly, and figure out for yourself why each wrong answer choice is wrong and each right answer choice is right. You have to develop an eye for the trap answers and for the logic of what goes on in CR questions.
For SC, likely you need to get better at hacking the questions and at using meaning as a key part of your decision making process.
For probability, find some good resources from which you can learn exactly how to handle the questions. You may get some key insights from responses by pros on Beat the GMAT. Then do enough practice questions to become expert at handling probability questions.
For advanced overlapping sets, see these two pages, and do plenty of practice questions.

Overall, to increase your score, work on things topic by topic. For plenty of by topic categorized quant questions you could set up a practice account in the GMAT area here,

Four weeks is a decent amount of time for achieving what you want to achieve. You might get some more insight into how to go about it from these two posts.
