whether to draw network with pen or pencil in ca final exam..its ok to use pencil or not.. because in you tube video i heard that network to be drawn with pen in exam
the teachers are suggesting that first draw with pencil and once the diagram is draw correctly just mark with pen also highlighting the critical path as well.
pencil is used because intially we are not sure that the diagram is correct or not so if we draw with the help of pencil we can erase and draw again easily. This will improve the presentation in the exam
It is always to take precautionary measures , since writing in pencil is not allowed also now they made mandatory to write in black pen also. so being safer side I would suggest first draw with pencil and after finalization mark with pen also or draw with pen if you are confident about diagram.
