Hi! I'm Builderguy135, but you can call me AC. I'm currently a junior that competes for West Windsor-Plainsboro High School North. In the 2017-2019 seasons, I competed for Community Middle School.

In Division B, I primarily did build events, but my favorites were Elastic Launched Glider, Hovercraft, Battery Buggy, and Road Scholar. In my 9th grade year, I also picked up Parasitology for Rustin Invitational, which quickly became one of my favorite non-build events. Currently, however, my favorite events are Sounds of Music, Codebusters, and Cybersecurity.

I'm also a test writer for many invitationals, including Rustin, Sierra Vista, Yosemite, and Yale; I've proctored and supervised events such as Road Scholar, Codebusters, Sounds of Music, Mission Possible, and Cybersecurity. All of my tests are publicly available below, but I just ask that the questions are not reused for other competitions!

Finally, I'm also a tournament co-director for the BirdSO Invitational! You can find more about the tournament at our website here.

2016-2017 (7th Grade, Div B)

In 7th grade, I competed for Community Middle School's. We only went to two invitationals that year, Rustin and Little Tiger. This was also my first nationals competition, which was held at Ohio State University.

2017-2018 (8th Grade, Div B)

In 8th grade, I picked up Road Scholar as a filler to do at regionals. I did very similar events as I did the previous year, but I also picked up Mystery Architecture.

2018-2019 (9th Grade, Div B)

With two years of experience, I decided to pick up many more events my freshman year of high school, most notably build events. My favorite event was Elastic Launched Glider, but I also competed in Battery Buggy, Mystery Architecture, and Roller Coaster with my brother, Sciolyperson1.

2019-2020 (10th Grade, Div C)

In 10th grade, I entered Division C, competing for West Windsor-Plainsboro High School North. I picked up Codebusters as a filler, as well as Ping Pong Parachute and Sounds of Music. Unfortunately, due to the COVID-19 pandemic, our team was unable to compete at Nationals. This year, I also wrote tests for several Division B invitationals, such as Road Scholar tests for the Raymond Park, Rustin, Jeffrey Trail, and Eagle Invitationals.

2020-2021 (11th Grade, Div C)

I became a lot more active in Science Olympiad my junior year, adding Digital Structures and Cybersecurity to the events I competed in. I also helped run SMEC, beginning the challenges in July with the Codebusters Scrimmage. This year, I became a lot more active in the community, and I was able to meet a lot of new people in the Discord! Due to the COVID-19 pandemic, I was also able to help out with a lot of competitions across the nation.

Feedback is appreciated for our tests! Please go to [1] to fill out a short form after you take each one of our tests.

Generally, my tests get progressively better over time; the tests in the 2019-2020 season really aren't worth taking at all. If you'd like to take my tests, I'd suggest starting from the ones written in 2021.

Experiences with Events


BirdSO Website

I made and run the BirdSO webpage, which can be found here!


I made an automatic Codebusters test generator, written in Python. Feel free to add the bot to your own server to practice with!


This is an automatic superscorer, which takes either a Scilympiad website or a CSV file as input.
