What Grade 9 works on

The core skills your kid will build this year.

  • Algebra I / II depending on placement
  • Biology: cells, genetics, evolution, ecology — with lab lessons
  • World literature: novels, short stories, structured analysis
  • World history: Renaissance → modern era
  • Foreign language (audio-led, conversational)
The Cullinan approach

High school is when essays carry real weight. The unit-test essay rubric + Claude grading + parent override gives you a transcript-defensible writing record. Spaced-repetition reviews keep concepts from earlier in the year live so finals aren't an act of god.
