CML Competition Tips for Grades 4–6

  • Practice in 30-minute blocks: Each real CML meet is 6 questions in 30 minutes. Train to that exact format using the interactive mock tests.
  • Explain your steps: Write out all work — even for mental math problems. This builds accuracy and helps you find errors fast.
  • Mix topic types: Don’t only practice one topic. CML meets mix algebra, geometry, and logic — so should your study sessions.
  • Review wrong answers deeply: Don’t just check the answer. Ask: where exactly did your reasoning diverge? That’s where growth happens.
  • Build number sense: Know your multiplication facts, fraction equivalents, and perfect squares cold — it saves time under pressure.
