I am a first year mechanical engineering whose interested in this field of study but right now i am unable to study mechanical subjects and moreover studying the subjects which are least related to mechanical engineering. The teachers in my institute are stupid and i don’t understand what they teach. I am being screwed into the madness of college, please suggest me a way to study properly according to my college curricular and also what a mechanical engineer should learn for sure.
