No fingerings are compulsory in exams - the general regs. say that 'any good practical fingering' is acceptable.
Doest that mean where it says: '4' on top of a note that you can use an open string instead of the forth finger?
Yes, although it's a good idea to get used to using your 4th finger, and they've suggested it for a musical or a technical reason, for example to avoid an awkward string crossing.
(This is assuming the note in question is a natural, that it's not an E flat or A flat!)
