1. 1

   Which method shown by the diagram provides the most reliable estimate of a ukulele's scale length?

   

   A Measure from the nut's fretboard edge to the 12th fret and double the result B Measure from the first fret to the saddle and subtract the nut width C Measure the complete length of the fretboard, including its overhang
2. 2

   A string is tuned correctly when open, but its fretted note at the 12th fret is sharp. Which saddle correction would normally improve its intonation?

   A Move its contact point closer to the nut B Move its contact point farther from the nut C Raise its contact point without changing its position
3. 3

   Why should final intonation be checked only after the action is set and new strings have stabilized?

   A Intonation can only be measured after the strings lose all elasticity B Action determines whether the tuner recognizes the open-string pitch C String settling and the amount of fretting stretch can change pitch readings
4. 4

   At the 12th fret shown, between which two points should string action be measured?

   

   A The top of the fret and the bottom of the string B The fretboard surface and the center of the string C The bottom of the fretboard and the top of the string
5. 5

   The image shows strings sitting unusually high above the first fret because the nut slots are too shallow. What symptom is most likely?

   

   A Open strings become flat while fretted notes remain exact B First-position notes tend to play sharp and require extra pressure C Notes above the 12th fret automatically become quieter
6. 6

   Which neck condition is represented by a fretboard whose middle curves upward toward the strings?

   

   A Excessive forward relief B A laterally twisted neck C Back-bow
7. 7

   What is the main setup benefit of the neat, downward-progressing wraps shown on the tuning post?

   

   A They create a useful break angle over the nut and reduce slipping B They shorten the vibrating scale length of the string C They compensate automatically for a misplaced saddle
8. 8

   Which relative-humidity range is generally suitable for storing a wooden ukulele?

   A About 15% to 25% B About 40% to 55% C About 75% to 90%
9. 9

   A short fret rocker rests on frets 5, 6, and 7 but pivots on fret 6. What does this indicate?

   

   A Fret 5 is lower than every other fret on the instrument B The nut slots are too deep C Fret 6 is high relative to its two neighbors
10. 10

    On a ukulele with an adjustable truss rod, which setup sequence is most appropriate?

    A Set neck relief, adjust action, then evaluate intonation B Set intonation, file the nut, then install and tune the strings C Lower the saddle, set intonation, then correct neck relief
11. 11

    Approximately how much will the 12th-fret action drop if 1 mm is removed evenly from the bottom of the saddle?

    A About 0.25 mm B About 0.5 mm C About 1 mm
12. 12

    Why might changing to strings of a different material or gauge require another setup check?

    A The new strings physically relocate the frets B Every string material requires a different body size C Different tension, diameter, and stiffness can affect relief, action, and intonation
13. 13

    What is the primary purpose of the stepped or angled saddle contact points shown in the image?

    

    A To give individual strings slightly different effective lengths for better intonation B To make every string sit at a different height above the frets C To prevent the bridge from transferring vibration to the soundboard
14. 14

    Which adjustment should be approached most cautiously because removing too much material is not easily reversible?

    A Turning a tuning key to bring a string to pitch B Deepening a nut slot with a file C Checking action with a ruler
