Leapforce exam, worried about that

Hey! ^{^} Yesterday i applied for work with Leapforce in spain, and today i got the answer that i can work, but i need to do the exam,

I Searched a lot about this topic and i'm worried because even the native people have problems with the exam, and my level of english maybe its not as good i would like for understand all.

WHich would be the best method for aprove the exam? Read all the guidelines every day? Do a resume?

I have the Link for the guidelines(website) but not the pdf of the guidelines, i will recive that in 15? (the day i can start to do the exam)? or i should ask them?

Thanks a lot! :)
