What are you checking?
These exchanges focus on three items requiring readback: heading instructions, SSR codes and runway hold-short instructions. They are a small subset of the readback requirements, not a complete radio course.
Check the instruction, the numbers and the callsign. If you cannot understand an instruction, ask for clarification rather than guessing.
