ROM Vs Initial estimate
(1) What is the range of a rough order of magnitude (ROM) estimate?
A. -10% to +10%
B . -5% to +10%
C. -50% to +50%
D. -300 to +75
(2) You are in the initiation phase and are doing an estimate for a project that requires a major software package for a healthcare system. What is the estimate range to use for this project?
A. -5% to +10%
B. -25% to +85%
C. -10% to +25%
D. -25% to +75%
Should we expect this sort of question on the exam? Am asking 'cos since PMBOK gave the value of ROM as hypothetical (it could be some other value), I feel the answers could vary.

ROM is +/- 50% and is used at
ROM is +/- 50% and is used at the beginning of the project since uncertainty is the greatest at the beginning of the project.
Therefore:
1C and I would say 2D since it is closer to +50% compared with B +85%
