Знание here is a singular abstract noun meaning “knowledge” in general. In Russian, many abstract concepts are normally used in the singular:

- Мои знания грамматики улучшились. – My (individual) bits of grammar knowledge have improved.
Грамматики is in the genitive singular.
In Russian, знание + Genitive is a standard pattern meaning “knowledge of X”:
- знание языка – knowledge of the language
- знание истории – knowledge of history
- знание грамматики – knowledge of grammar
English uses the preposition “of”, but Russian often uses just the genitive case without a preposition to express this relationship.
