I took this information from the syllabus for the Royal Conservatory of Music here in Canada. If you're playing the Bouree in Suite No. 3 in C Major, the studies that are given for you to chose from are the following:
New Method for Double Bass: part 1–III [ER 263] RIC
• one of nos. 34–46
Nouvelle technique de la contrebasse, vol . 2 LED
• etude 11
• etude 12
New Method for Double Bass, book 1 FIS
• exercise in broken chords (pp . 104–105)
• legato exercises (p . 101)
• legato exercise on two strings, no . 5 (p . 103)
• no. 4 or no. 5 (p . 89)
Thirty Etudes for the String Bass FIS
• one of nos. 7–18
Storch, Josef Emanuel, and Josef Hrabe
Fifty-Seven Studies for String Bass, vol . 1 INT
one of nos. 8-18
Mind you, this syllabus is dated from 2004.
And in case the school requires you to use an actual published copy (not a printed/photocopy); The book that I used to play the Bouree from is called Solos for the Double Bass Player
by Oscar Zimmerman.
That link contains the solo and sonata works that at or around your skill level for the RCM. Although, I'm not entirely sure how many of those are actually playable by you. Best of luck with your audition!
