Project Koa (“Warrior”)
HSA NGSS Science Prep Simulations
Built for the students of Wahiawā Middle School
Practice until the real test feels familiar.
These simulations were designed by Joseph Avery, a science teacher at Wahiawā Middle School, to prepare WMS students for the HSA NGSS state science test taken in 8th grade.
This platform has taken over 1,000 man-hours to build, and it was created out of love for the students of WMS. As a teacher at this school, I genuinely care about you. I want you to be prepared, confident, and fearless. No other school in the state has this.
Full-length practice test
A complete HSA-style exam for 8th graders. Work through the simulations first, then take it when you feel ready.
The Mission
Prepared. Confident. Fearless.
The goal is not just to memorize answers; it is to train your brain to slow down, read evidence carefully, compare data, eliminate weak choices, and use scientific reasoning under pressure. If you can learn how to use test logic and analytical thinking to pass these simulations, you will be more than ready for the real thing.

Student reminder: These are supposed to feel difficult. That is the point. When you struggle productively, analyze evidence, and figure out why an answer works, you are training the same thinking skills you will use on the real HSA NGSS science test.
