- Why bottom-up estimating is the most accurate method but requires a detailed Work Breakdown Structure (WBS).

- How to apply the three-point estimating PERT formula (O+4M+P)/6 to account for uncertainty in exam scenarios.

- The critical distinction between the cost baseline (work package costs + contingency reserves) and the total project budget (cost baseline + management reserves).
