I am unfortuate in that I cannot get to my upstairs as I have no way of accessing it. I am unable to use the stairs now due to the muscle weakness in my lower limbs and therefore unable to gain any view or elevation as directed in part two of the exercise.

I am also somewhat housebound because I have no transportation to get me out at the moment so I cannot adapt the exercise. Once I am in a position to do so I may well revisit this exercise.

I do not have a manual camera so the first part is unable to be completed either. I feel that I failed miserably with Exercise 3.3. I wonder if this has been considered when writing the course material? Those of us disadvantaged by mobility or disability and those of us who just simply do not own a manual camera?
