I would rather be positive than critical at this point. I hope the following information helps.
In the https://nar.org/Level1HPRCertificationProcedures page, section 4, subsection 6 I found the following information.
Also during the safety inspection, the Level 1 High Power Certification Candidate will be expected to provide oral answers to technical questions related to the safety and construction of their model. The questions may include (but not limited to) identification of the model’s center of gravity and center of pressure, methods used to determine model stability, and interpretation of the rocket motor’s designation.
In my opinion, the key metrics a certification candidate should know are:
Location of CP, CG, the stability margin.
Speed off the rail.
Thrust to weight ratio.
Decent rate.
A simulation that shows the above information.
They should have their application on hand and filled out the best they can.
