In both exams, I didn't get a direct question on ITTO. However, you may get a scenario that needs you to think about what Input/Tool/Output is used in the area.
Math was a very easy 3 - 4 questions only. one of them was if you CPI and that much and your SPI is that much, what is your status.
Regarding the input/output. I used a single letter for each of Input/Output as follow:
Managment plan
Scope = O
Schedule = S
Cost = $
Requirements = R
Resource = E
Risk = !
Communication = K
Procurement = P
Stakeholders engagement plan = H
Change management plan = C
Baseline: B
Scope Baseline = B1
Schedule baseline = B2
Cost Baseline = B3
Performance measurement baseline =Z
8 = Basis of estimate
Project Documents
Change = c
Change log = g
Project Life Cycle = y
Development approach = d
Management review = m
In this case for Close phase or Project the input can be :
koal for (communication, issue log, assumption, lesson learned)
Bb (business case and Benefits management)
8MQ (for the basis of estimate, milestone, Quality)
and so on, The above is not the complete Input/Output. This will give you the idea of how it works. After writing them down, it requires you to review them a number of times until picture it in your mind.
For the tools, I used sign. Example for Variables Analysis (used wave sign) for Trend (used 45-degree line), for Performance (P), for cost-benefit analysis ($), and for parametric different signe.....etc. This technic was very helpful. As mentioned before, at this point I know every single ITTO for each knowledge areas.
