OBSERVATION

   2a.This question required the candidates to convert a block given in isometric to orthographic view. The solution is required in first angle which implies that a side is viewed from one end and projected directly to the opposite side. Most candidates demonstrated lack of this fundamental principle . The solution is shown below

   2b.candidates were required to draw a parabola by drawing a directrix. The given  focus and depth are then set off  and the distance between the focal point and the depth is divided evenly to  get a suitable curve as shown in the solution below.
