720 Mock to 740+ in 8 days?

Hello, seekingadvice94. I think you are in fine hands with Target Test Prep regarding Quant. Since SC seems to be a sticking point for you, I would recommend checking out this SC flowchart for starters. It should help you appreciate that although a finer sense of grammar will help you at the uppermost level of SC questions, SC is more about meaning than anything else. You should focus on small sets of dedicated questions, no greater than about 10 questions at a time, to see if you can achieve the same level of proficiency across Easy, Medium, and Hard questions that TTP recommends for Quant. If you are working through an OG, then you have plenty of questions to practice, but if you do not have such access, you can use the Practice Question Banks directory and tag official questions to try out. Read the analyses for the questions you miss or maybe guess on. Many community members and Experts—GMATNinja, daagh, VeritasKarishma, AjiteshArun, and DmitryFarber come to mind—provide in-depth responses that address just about any concern you might have about a particular issue. When you learn from the best, you start to think like the best, and 8 days, believe it or not, can leave you with enough time to make significant inroads in your self-identified worst area. Just do not fall into the trap of thinking that exhausting all the SC questions from the OG will necessarily make you better at them. Get to the bottom of why you are making errors, and you will set yourself up for success on the next similar question. Try as GMAC™ may, there are only so many ways to twist a sentence into a pretzel to test grammar and meaning. Maybe 50 questions will prove enough for you to learn the most crucial lessons. But I guarantee 300 questions will be unnecessary.

Good luck with your studies.
