PHYSICS-13 · Advanced · ENGLISH · PLANNED
Predict, observe a demonstration, draw a model, then test its limits.
Study time is an initial activity estimate, excluding extra reading, revision and extended laboratory or project work. Videos and question bodies have not been produced by adding this outline.
Complete these courses or demonstrate equivalent knowledge. These are recommended prerequisites, not enforced enrolment locks.

Combine all three sections: Fit a simple expansion model and label observational assumptions. Submit an original worked artifact, evidence or tests, assumptions and a reflection. Rubric: correctness, method, practical usefulness, reproducibility and communication. Self-reviewed, not certified.
6–12 balanced questions sampling every section of Relativity, Gravitation and Cosmology, including interpretation, calculation or reasoning, a misconception and a new application. Passing is 70%; review errors before retrying.
Diagrams, virtual experiments, data analysis and simulations. Guided work leads to an independent attempt, with a diagram, explanation, trace, calculation or tested artifact. Question bodies are generated when opened in your private learning path. Programming submissions are stored as text; the platform does not execute submitted code.
Use original or appropriately licensed datasets. Practical science activities use models or supplied data unless a qualified supervisor has reviewed a physical experiment.
