For Mod 6, schools could ask for practicals on basic aircraft maintenance tasks, which can help assess the practical IQ of students when it comes to hands-on tasks. Similarly, for Mod 7, a good skills test could involve interpreting maintenance manuals or performing component disassembly and reassembly tasks.
These activities not only test technical proficiency but also challenge students' problem-solving abilities, much like an IQ test, by evaluating their capacity to think critically and apply knowledge effectively.
