Observation

Candidates were given two views of a casting in first angle orthographic projection and were expected to draw it in freehand isometric sketch using pencil and eraser only.

Most of the candidates attempted this question and their performance was okay.

However some of the candidates did not make X the lowest point.

Candidates were expected to do the following:
