This is a old course of mine so please pardon the background noise (if any) and audio quality. The whole course contains some 35 questions which have general tendency of repetition in GATE examination ( Graduate Aptitude Test in Engineering, an examination that primarily tests the comprehensive understanding of various undergraduate subjects in engineering and science in INDIA).
Its highly recommended to the students to first complete their whole syllabus before opting for this course. This is a highly advanced course which will include questions from almost all the sections of mechanical engineering. The course is designed especially for INDIAN students preparing for GATE examination.
However, even if you are from outside India, you can still opt for this course to boost up your knowledge.
