Raising CR by 100 pts in 7 weeks?

As the title suggests I need to raise my CR from a 550 to a 650+ by the time October comes.

Up until this point I have been prepping to raise my Math score by over 150 points. As a result, I have given little attention and time to my CR which has not changed since June. I don’t know how to tackle it, especially the reading passage. I’m open to my advice, guide and recommendation from you guys.

Thx

It’s hard man, CR is the section most people found perplexed, may I ask whether u are Americans or international students?
