The rubric is on the challenge page (VIQC Middle School - STEM Research Project: Biomimicry in Engineering | Online Challenges) under Technical Details and Judging Information. Have someone else check your entry against the listed criteria, and see if they can give you feedback. All of the OC judges are volunteers, so your simulation should get you pretty close to the real outcome.
There’s a possibility that you didn’t miss anything… let me explain: at some high-level events there can be multiple “perfect” scores on the rubric. For example, a few years ago I was judging design award at the world championship, and we had to make our decision between 6 teams that all had “perfect” rubric scores on their engineering notebooks. While the rubric is an important tool that judges used to help make their decision, it it’s not the mechanism that analytically makes the decision on an award. (mostly, the rubric scores narrow the field). There is the human factor, the judges conducting the interview or reading the project, that the final award is based upon.
This advice is spot-on. You really won’t get any different results seeing the rubric used for your project.
