When you are using Goocus, the points are given to you when you take actions that are considered effective to your learning.
The points are allocated by the creator of the content. As to what actions give your more point depend on the account.
At default setting, you earn many points when you had a correct answer to a quiz. However, finding your own way to earn many points is part of the fun of studying with Goocus. Therefore we do not disclose the details of the point allocation mechanism.
When you receive points, they will be shown on your Timeline. So you can find out, to a certain extent, the allocation of the points.
