Test Details

Official Cambridge Practice Exam

Academic CBT

Passage 1 · Roman Aqueduct Engineering

Questions 1–6: True / False / Not Given

"Roman aqueducts moved water purely through gravity, calculated at an exact downward gradient of 1 in 5,000 without the use of mechanical pressure pumps."
Sep 3, 11:17 AM
Can you explain why Question 1 is FALSE instead of NOT GIVEN? I want to make sure I understand the Cambridge rubric difference.
AI Examiner· Sep 3, 11:17 AM
On the Cambridge CBT exam, FALSE means the statement directly contradicts fact in the passage:
  • The passage states aqueducts operated solely by gravitational slope.
  • The question states they required steam pumps.
  • Because steam pumps are explicitly ruled out by natural gravity, it is conclusively FALSE.

@PrepPath What is the average weak criterion for Batch A's Task 2 essays?

AI Academic Co-pilot:

Batch A averages Band 6.5 in Lexical Resource due to repetitive linking words. We recommend assigning Cambridge 18 Test 2 Reading Passage 3 for contextual academic collocations.
