Observation

It is impressive to note that many of them succeeded in:

-           laying-out properly, both the internal and external walls at the corners and junctions;
-           labelling correctly, the various room (spaces) on the floor plan.

However, few of them failed to:

-           draw the plan to scale 1:100 as specified;
-           dimension the drawing;
-           show the doors positions with the conventional symbols;
-           include the sectional line A – A.
