You can have all the potential in the world, but if you're a chemistry student who likes to improvise, and you blow up the classroom every time you perform an experiment, you're not going to be considered competent.

Not quite so. If you always, even in such simple experiments as mixing water and cooking salt, manage to create an explosion - then you are really gifted.

Spoiler:

Do you remember the words of Ms. Chevreuse? "What can be dangerous about alchemy?" - it is considered to be just as safe as the above chimistry experiment.
I bet that Translation spell is far beyond the level of ordinary magic student, and I doubt even Old Osman can create something that difficult(nobody even mentioned such a solution!). Now, could you please name the one that produced such effect without much effort?
