About

Hello everyone! Welcome to my 15:5 study space aka Bite-sized Busyness (sorry if that is cringe)
Study spaces help you concentrate, focus, and get work done! On most weekdays, we will have two or three cycles of the 15:5 Pomodoro timer! In the breaks we will play games like Gimkit or Wordle.
Expect productivity and fun :))

Hey guys! I’m Mattis, a homeschooled 9th grader currently living in Shenzhen, China! I’m really into art (digital and ordinary pen+paper) and I love writing fiction novels (two of them, Ebse Nexus and Bombardment B, are nearly done), which are typically a blend of sci-fi and fantasy. One of my stories, Hamburg Shootout, is now complete! Update: as I have been temporarily suspended as a tutor, it will not be possible for me to host sessions as of now. Since I learn mostly through Khan Academy videos and exercises, I am really thankful to Sal Khan for making this possible. I used to be very active on Khan Academy (before I got muted for some reason) and I decided to come here to help people with R&W, art, and creative writing. I’m a total extrovert and can always be found attending and hosting sessions and answering people’s questions!! I also love making friends here so feel free to message me if you want to talk :) I’ve been shortlisted for the John Locke Essay Competition, scored 89% on an actual university German test, and gotten a 5 on my Environmental Science AP test. Here are some of my achievements on SHW: —Having hosted 350 sessions —Having reached 1200 helpful and super helpful ratings —Having attended 250 sessions —Having won the Historia event on schoolhouse. —Having met Sal Khan. Some fun facts about me: I joined Schoolhouse on August 24, 2024, so I’ve been on it for 1 year already! I became a tutor on October 14, 2024 at 7:10-7:11 pm GMT+8. I reached Bronze Level (500 SP) at 10:49 pm GMT+8, November 8. I became a tutor in Enrichment Subworld on November 12, at 5:14 am. I reached Silver Level (1000 SP) at 8:12 pm GMT+8, November 30 (last day of November yippee) I reached Gold Level (2500 SP) at roughly 11:06 PM GMT+8, Jan 10, 2025 (got a shoutout at 5:24 am). I reached Platinum Level (5000 SP) at 12:07 AM GMT+8, July 3, 2025 (a few days after my birthday). I got my shoutout at 12:43 am. Average SP/day (updated weekly): 17.32 I’m a big fan of Duolingo! I have a 1950+ day streak (over 5 years now) and 1.7 million XP. My MBTI Personality Type is ENFP-A, Campaigner. My Hogwarts House is Gryffindor. I know a lot of people really want to be Gryffindor, but I actually prefer Slytherin. My favorite games are: Minecraft, Krunker.io (#1 class: Triggerman), War of Sticks, Gimkit (recently became a huge fan), and Chess (on chess.com or lichess.org). My favorite books: Harry Potter, LOTR, and Percy Jackson. I’m hosting an ongoing session on the latter. My favorite movies are: Inside Out, Incredibles, Star Wars My favorite songs are: Unstoppable, Chandelier, When We Were Young, Hello My favorite colors: Purple, Indigo, Turquoise, Black. I hate orange. As for hobbies, I have a ton of them: Writing fiction, chess, speed typing (avg. speed roughly 80-90 wpm, record 117 wpm), drawing my characters, and reading books. I absolutely adore drawing and try to make at least three a day. Right now I’m learning German, Mandarin Chinese (both on Duolingo), and conlangs, mostly Ebsian, a language I created for my stories.
