LR and Reading Comp Tutors

Dear 7sagers,

Hope everyone is doing well. I was wondering if anyone has had a great experience with a tutor that they can recommend. I am doing pretty well on LG so the 2 sections I really need help on are RC and LR. I average a -5 on LR and I am hoping to bring it down to a consistent -2. For RC my scores I fluctuate pretty dramatically from -8 to -4 so I am looking for a way that can help me get a -4 or less consistently. The RC sections that I do well on tend to be ones where I am very familiar with the content, so my goal is really to find a plan that's "content-proof" which would allow me to get the same score regardless of my familiarity with the content, which I have been told is the key to a -4/-3 on RC.

Any advice or recommendations is truly appreciated.

Thank you!
