Apprentices couldn't just turn into wizards because they wanted to.
To 99% of all apprentices, becoming a wizard could be well considered the ultimate goal. Under such a circumstance, aiming for the path of truth as an apprentice was downright impossible.
However, it seemed both Sunders and Flora assumed that the otherwise absurd challenge was something possible for Angor. Not only that, but they also expected Angor to aim higher after becoming a wizard, which "might take him a lot of time".
To them, the question was whether Angor should "take time" to accept the challenges. Unfortunately, Angor did not have such high hopes for himself. He did not have the confidence to become a wizard in the first place.
