Need Help with CARS ASAP!

Hello guys,

I was wondering if anyone who is good at CARS would be willing to teach me a few strategies? I am very slow at reading and comprehending the entire passage. Maybe I don't know what exactly to focus on while reading.
My test is in 5 weeks. I have tried many different approaches, but they all failed. I'm at the verge of giving up, so any help at this point would be greatly appreciated.

Thanks in advance.
