Magic should not be consistent, nor should characters.
Magic = Deus Ex Machina.
Whenever your character needs to do something, there will be a spell that exactly fits their needs, and said spell will always be in the wizard's ability level. There are no limits on magic power or spell type, ever, except to create dramatic tension. (These 'limits' disappear when your character actually decides to DO something, of course.)
Magic never has to be explained, because it's magic, even when you base your whole story around it.
Magic and universe rules don't have to be consistent when it comes to your MC. Did your Lvl. 1 wizard MC shapeshift into a dragon, despite having earlier established that transforming into a dragon is an ability only a Lvl. 100 wizard can do? Well, you don't have to acknowledge it, your reader will never question it or see it as a plot hole.
If your MC is in a notoriously strict school or military area, they don't have to follow those silly uniform or conduct rules. No, while everyone else must wear the same thing every day, they can wear their stylish outfits and no one, neither the authorities nor their peers, will care! They can also stay up late and sleep in during mornings despite the strict sleeping scheduels. Why? It helps establish to the reader that your MC is special. The fact that your MC has unique powers few others possess, or is the only one to face the Dark Lord and make it out alive, or that they're the prince/ss of a kingdom won't be enough for the reader to get the message.
