About

A freshman from Indonesia but currently studying in Singapore! I just love algebra and statistics so I'm here to help with that!

I'm also here to learn more about DSAT and Calculus since I'm planning to get into a university in the US. I also speak (almost) 4 languages, English, Indonesian, Chinese and Japanese. In my free time I like to do ballet, play the piano, watch anime, and sleep! :D
