Why is the Aqualine evolution free now???

Hi there,

The Aqualine avatar was unlocked summer 2020 due to Missions being removed from the site. To previously unlock Aqualine, you would need to master a certain number of skills in Missions, and once Missions were removed, Aqualine was unlocked to all users.

I hope this helps! Please let me know if you have any further questions.

I have a question. Why was missions removed?

Hi there,

Course mastery has become the main learning system since the removal of missions. This comment gives some insight into why missions were removed: https://support.khanacademy.org/hc/en-us/community/posts/360070675772/comments/360011217992
