Question paper pattern:

• The SEE question paper will be set for 100 marks and the marks scored will be proportionately reduced to 60
• The question paper will have ten full questions carrying equal marks.
• Each full question consisting of 20 marks.
• There will be two full questions (with a maximum of three sub questions) from each module.
• Each full question will have sub question covering all the topics under a module.
• The students will have to answer five full questions, selecting one full question from each module.

Note:

• To illustrate the concepts of operations of turbines, pumps, conventional machines like lathe, drilling, milling, grinding etc., the instructions should be blended with video presentations and visit to the laboratories/ machine shop concerned.
• Demonstration of soldering, brazing and welding should be arranged in the workshop.
• To illustrate the fundamentals of CNC machining and turning centers and robots, video presentations should be adapted in addition to class room instructions.
• The boiler mountings and accessories should be shown in the engine lab.
• Assignments should be submitted by students on materials, sources of energy, global warming, welding processes, robots and their applications. These assignments should be given due credit in awarding CIE marks.
