Note: – All above around 30 theory questions that given does not guarantee to come as it is all in exams, but definitely few of above questions will help you to score passing marks or near to 50-60 percent marks by inclusive of your practical exams performance…..so an example we will consider a     tough case, that if you performed well in your practical exams then you could score near to 20-25 out of 30 marks then remaining theory if you come across with such above few questions and write well proper points as per the requirement of the question then you can score around 10-15 marks out of 70.

So 25+10=35 or 20+15 = 35 which results to pass.
