The CCT mock exam is the centerpiece. Cal Tech runs the full 110-question timed simulation under real exam conditions, scores your readiness and estimated pass probability by Body of Knowledge domain, and queues SM-2 spaced-repetition reviews so the right concepts resurface before exam day. Copy any prompt below, paste it into MetTutor, and export your work to Word, Excel, PDF, CSV, or TXT for your records.

110-Question Timed CCT Mock Exam
01
CCT MockTimed SimStart the full timed mock. Begin the complete 110-question ASQ CCT mock exam under real exam conditions — same domain distribution and time pressure as exam day, with a live countdown. Hold my answers until I submit, then score the whole session.
02
ReadinessScore my readiness. I just finished a mock. Give me my CCT readiness score and estimated pass probability, with a domain-by-domain breakdown across the Body of Knowledge — show me exactly which areas are dragging my number down.
03
Timed SimHalf-length pacing run. Run a focused, timed 55-question simulation weighted toward Measurement Uncertainty and Calibration, where I keep losing points. I want to practice my pacing without committing to a full session — flag any questions where I ran long.
Spaced Repetition & Study Planning
04
SM-2 Spaced RepToday’s review set. Based on the questions I’ve been missing, queue up SM-2 spaced-repetition cards so the concepts I keep forgetting resurface at the optimal interval. Start today’s review and tell me what’s scheduled next.
05
Study CalendarBuild my study calendar. My CCT exam is six weeks out. Create a personalized study calendar around that date — fold in my SM-2 reviews, daily quizzes, and mock-exam windows, sized for realistic 30–45-minute sessions after my shift.
06
Daily QuizKeep the streak going. Give me today’s daily quiz, then tell me which Body of Knowledge domain to drill next based on what I miss — keep it short enough to fit a coffee break.
Targeted BoK Domain Drills
07
BoK DrillUncertainty drill. Build a 15-question CCT-level drill on measurement uncertainty — Type A vs Type B evaluation, combined standard uncertainty, expanded uncertainty, and coverage factors at k=2 — with full worked solutions and the reasoning behind every correct answer.
08
BoK DrillISO 17025 drill. Drill me with 12 CCT-style questions on ISO/IEC 17025:2017 — competence, metrological traceability, certificate content, and ensuring the validity of results — and explain why each correct answer is correct, citing the relevant clause.
09
BoK DrillFundamentals & traceability drill. Give me a 10-question drill on calibration fundamentals and traceability at CCT difficulty, then tell me how my answers move my overall readiness score and what to review before my next mock.
Uncertainty in Practice
01
Explain Type A versus Type B uncertainty evaluation with examples from an actual calibration, and show how they combine into a combined standard uncertainty.
02
Why do we report expanded uncertainty at k=2 for 95% confidence, and what exactly does the coverage factor do to my combined standard uncertainty?
03
What’s the practical difference between TUR and TAR, and why does a 4:1 ratio matter when I’m deciding whether my reference standard is good enough for the tolerance on the unit under test?
Traceability & Calibration Principles
04
Walk me through what metrological traceability really requires in practice — the unbroken chain, a stated uncertainty at every link, and why an accredited source matters for the calibrations I sign off on.
05
What do “as-found” and “as-left” mean, why do we record both, and how does as-found data feed into calibration interval decisions over time?
Quality & Conformance
06
When I put a statement of conformity (pass/fail) on a certificate, what does ISO/IEC 17025:2017 require, and what role does measurement uncertainty play in that decision?
Uncertainty Budgets — Type A/B, k=2
01
Type A/B BudgetPressure gauge budget. Help me build a Type A/B uncertainty budget at k=2 (95%) for a digital pressure gauge: reference U=0.012% (k=2), resolution 0.01 psi, repeatability from 10 readings (σ=0.018 psi), and a temperature effect of 0.002 psi/°C over ±2 °C. Walk me through combined and expanded uncertainty step by step.
02
Type A/B BudgetType A from repeat readings. I measured a gauge block 10 times: 25.001, 25.002, 25.000, 25.001, 24.999, 25.002, 25.001, 25.000, 25.001, 25.002 mm. Walk me through the Type A evaluation — mean, experimental standard deviation, and standard uncertainty of the mean — and show how it folds into the budget.
03
Type A/B BudgetCombine components. Combine these into a combined standard uncertainty and expanded uncertainty at k=2: a Type A of 0.4 µm, a Type B from resolution of 0.3 µm, and a Type B from the reference certificate of 0.5 µm (k=2). Show every step and the final reported value.
Ratios, Conversions & Reporting
04
Advanced TURTest Uncertainty Ratio. My UUT tolerance is ±0.5% and my reference’s expanded uncertainty is 0.10% (k=2). Use the advanced TUR calculator to work out the Test Uncertainty Ratio and tell me whether I clear the 4:1 minimum — and if not, by how much I’m short.
05
Unit ConverterCalibration-point conversions. Convert a calibration point of 150 psi to kPa, bar, and inH₂O, and show the conversion factors so I can sanity-check the values before they go on the certificate.
06
Sig FigsRounding the result. My measured value is 9.80665 and my expanded uncertainty is 0.0123. How should I round and report the result and its uncertainty with the correct significant figures, following good metrology practice?
Working With Your Data
07
Spreadsheet UploadAs-found data review. I’m uploading
asfound_pressure_2026.csv with a month of as-found readings. Review the data with me, flag any drift or outliers, and help me interpret what it means for this instrument’s stability — I’ll export the summary myself for the calibration history.ISO/IEC 17025:2017 on the Job
01
What does ISO/IEC 17025:2017 §7.6 require for evaluating and reporting measurement uncertainty, and how does that translate to what I actually put on a calibration certificate?
02
According to ISO/IEC 17025:2017 §7.8, what must appear on a calibration certificate, and which required items are most often missed or done wrong in day-to-day practice?
03
What does §7.7 (ensuring the validity of results) ask a lab to do — intermediate checks, control charts, proficiency testing — and which of these apply at the bench level for a working technician?
The NIST GUM in Practice
04
Using the NIST GUM, walk me through the full uncertainty workflow as I’d apply it to a routine calibration — model the measurement, identify the sources, evaluate Type A and Type B, combine, and expand at k=2.
05
What’s the difference between standard uncertainty, combined standard uncertainty, and expanded uncertainty in the GUM, and where does each one show up on a calibration certificate?
