The grade sets how in-depth the set should be.
- 6 – Essential: the core concepts, a few exercises.
- 7–8 – Good: complete explanations and a good number of exercises.
- 9–10 – Very high: more detail, connections and questions.
- 10 cum laude – Maximum: the most in-depth level.
If you start from your own material, Vesta stays faithful to what you uploaded: short material gives a shorter set, whatever grade you choose.
