I just need your help - which of the kreutzer studies is at a grade 8 standard? Which out those frage 8 studies are the easiest to learn.

Reason why i am asking is because i need to learn one for my RSAMD audition.

Thanks

No. 8 or No. 10 would be suitable. Neither are easy to learn, in fact at the level you are talking about nothing is easy to learn. Technical and/or musical difficulties will come at you in different guises.
