Once you were 12, you needed to study 8 years at the magic academys. If you didn't reach apprentice stage by then you could study antother 4 years.
When you reach apprenticeship, you could be taken as an apprentice by an mage with level 4 or higher.
You are an apprentice untill you reach the mage stage.
The humans measured mana with beast mana scrolls.
Magic is very connected with physics and science. Mana is just drawing a diffrent type of energy out of the air and turning it into kinetic energy and stuff like that.
Of course one also needed high mental concentration, imagination and knowledge to perform spells.
Talent ranking(Mana pool without training):
no talent 1-5mp
Level 1 6-10mp
Level 2. 11-20mp
Level 3. 21-30mp
Level 5. 31-50mp
Level 6(Legendary talent) 51-100mp
That was the auxilary chapter. I hope it helped you to better understand the rankings and powerlevels of the mages.
