If all goes well, there shouldn't be much to say in this section.
For Part I (Assembly)
provide
a description of any problems you encountered,
or of alternate techniques that you developed.
Also include any suggestions for additional tools that might be useful
or other ideas for how to improve the assembly process.
For Part II (Testing)
say similar things about your experience in measuring the frequency response
and the differences (if any) from your 241 experience.
Note that the actual data that you collect
belongs in the next section rather than here.
There are a few simple questions imbedded in the instructions.
Be sure that your discussion contains the answers to these.
