It looks like JOhnlovemusic read my mind, I was going to suggest scales with four or more sharps/flats.
This may be my first time hearing about a student allowed to pick their scales. I've seen some situations where the teacher/judges tell the students to play some scales then all of a sudden request for Cb major, just to see if the student is really prepared.
But then again, I've read on another clarinet board where a student flubbed on C major (used B flat by mistake)
In any case, I like JOhnlovemusic's suggestion. If you have sufficient time to prepare those two scales, by all means work on them.
Good luck, I hope you do well
