Practical exam.
Although it sounds the same as the practical exam of the entrance exam, it's totally different.
While in the entrance exam, you have to show your skill against the mana puppet - which is programmed with stats.
After you fight against that mana puppet with your full power, AI will make a detailed report from the data it collected during the fight.
On the other hand, in the practical exam of the mid-terms, you will be given a mission.
That mission is very simple.
The academy will provide you with a target monster. You have to kill it and come back safely.
You would be ranked on how quickly and safely you completed the mission.
Isn't it easy?
It would have been quite easy if the dungeon regarding the exam was explored.
However, Roaring Cave was only partially explored. Many of the passageways of that cave were unknown. No one knew what kind of monsters were waiting for them.
