Hey Merlumia. The answer to your question is at the end of this post and my god! You're gaining pp very quickly.
If you keep playing osu! 24/7, you might be able to enter the osu! world cup 2016. Who knows?
I have yet to see what plays you will play in the future, hoping it will be amazing (especially for someone who started playing last week)!
Enjoy osu!
And remember, don't chase skill, let skill come to you!
