Would a skin assessment assignment be more difficult than an assignment on Eye or Ear assessment?

Would a skin assessment assignment be more difficult than an assignment on Eye or Ear assessment? Trying to select a topic to write a discussion post about. I will need to;

1.Discuss client teaching specific to health maintenance or preventative healthcare for that region.

2.Describe how you will do the assessment and what equipment you will use.

Should I select 1. Skin 2. Eyes or #. Ears
