# Assistant Professor in MECHANICAL ENGINEERING Syllabus Kerala PSC 2022 Assistant professor in government engineering college exam published in 2022. The syllabus comprises of two parts as given below

• Mode of Exam: MCQ (OMR)
• Exam contains 100 Questions
• Each correct answer carry one mark & 0.33 detected for wrong answers
• Total time allotted :  1hr 15 min

Do you believe that all questions comes from the syllabus  ?

NO, Thorough knowledge of subject is required  since question from outside can be expected. In the recent years we can see a trend of deviation in questions in the technical exams conducted by the Kerala PSC.

Will only studying topics in syllabus fetch me a GOVT Job?

Do not blindly follow the syllabus rather have  good technical knowledge of your subjects. If you check the previous year papers you could find out many questions coming outside the syllabus in all technical exams by Kerala PSC.
