Should I change of profession or nah?

I study in dental assistance and today I failed an test and I had now to leave in actual group to integrate into a new group to redo the subject that I failed (it could take for a month to a year to be back, it’s works like that at my school) but this isn’t my first failure in this profession, should continue in this profession or leave and try a another one since i think this isn’t made for me finally?

Should I change of profession or nah?
