it depends on the particular school in question. in most engineering faculties mechanical engineering is the toughest. it all depends on the combo of lecturers in d dept and also on a students ability cos wat u term difficult may not b same to another. my 2 cents

using Nigeria as a case study I have come to a conclusion that chemical engineering is the most challenging engineering department in any Nigeria university,tho last week a friend of mine whose elder bro studied electrical engineering didn't agreee to my supposed conclusion so I decided to hear from you guys,am sure I have alot of engineering students here in nairaland so I am hopeful to get convince if my prediction ain't worth it....Thank you.
