2ND YEAR PRACTICAL
The second year Motor Vehicle Mechanics Practical is carried in a very unique way. This is because in first year most of the practical work was involving worn out components from non-functional Engines. However 2nd year practical will mostly involve Live Component and even functional components inorder to drive in the required message.
