Applying for JAG

Hello! Im a dude for Norway wanting to become a dentist, since the grade requirements from high school is ridiciously high in Norway, im going to head abroad :)

It seems to me that JAG is one of the few unis I can go to that will ensure an authorisation so im kinda desperate to pass this entrance exam

Does anyone of you have some tips/notes how to pass the exam and what books/topics i should look into?

Thanks :)
