If you IR takes you to Birmingham (egbb), then watch out for the hold at either Ebony or Grove (if you are approaching from the south...) Sometimes you get straight in vectors from your descent and other times you get the unplanned hold...! It has happened in the IR test!
For your own IR, cover all possible outcomes. Remember, a superior pilot carries out superior planning to prevent themselves having to show their superior skills
If your IR is in the afternoon though, larger airports that can make you hold should be quieter which may help you pre-empt the situation...Good question though!
Good luck..!
