Advice for students of all disciplines (not just carpentry):
Attune yourself to the notes of the western musical scale. This can aid in covertly sharing answers during multiple choice assessments. Hire one peer to broadcast the solutions by humming the tune corresponding to the pattern of correct letters. For example, if the answers to questions 1 to 5 are A, D, A, C, B, then the hired peer will hum the notes of the same notation. One must be careful not to orally tone sharps or flats as this can create confusion in one’s attentive cohorts.
Students should be aware, however, that this method will be futile for tests presenting more than 6 possible solutions per question (as is often the case for topics like topographical quantum dilation dynamics and roof math).
