Need an RC tutor for Jan test

What the title says pretty much

I am taking the test for the last time in January and I need to improve my RC drastically.

For context I score -1 to -4 on just about every LR section but score -6 to -9 on most RC sections.

I’m looking for someone who can adhere to the strict timeframe and also can show reputable improvement proof of some sorts.

Thank you for the help or advice.
