Common mistakes

  • Dividing by zero
  • Reversing inequality when multiplying by negative

Review and practice tests

1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for HSA.REI.C.6.
