A.3Research methodology
Excellent
Criteria Feedback
The research question is clear, focused, and consistently linked to the investigation’s calculations and conclusion.
You communicate the purpose of the modelling well and give the reader a strong roadmap through the work.
Your method is complete and carefully chosen for the task, using orbital modelling, transformations, vector methods, and root-finding appropriately.
The research question is a little long and could be tightened further without losing focus.
A few modelling choices would benefit from slightly more explanation, especially where assumptions are introduced.
Some background explanation could be shortened so the mathematical purpose is reached sooner.

B.2Use of terminology and concepts
Excellent
Criteria Feedback
You show strong command of the relevant astronomy and mathematics vocabulary throughout the investigation.
You apply orbital concepts correctly and build the model from appropriate physical and geometric relationships.
You use terminology such as eccentricity, perihelion, rotation, velocity vectors, and deflection accurately and consistently.
One or two relationships could be explained more explicitly so the conceptual link is easier to follow.
A small number of symbols and variables are introduced without enough verbal clarification at first.
There are minor issues with precision and notation, but they do not weaken the overall understanding.
