I'm an engineer - I am now at a point in my career where I manage a branch office, hire/fire staff and own part of a decent sized company. My average in the last two year's of uni was 75%. No one has ever asked me and no one has ever cared - it is enough that I can put the letters "B.Eng." behind my name.
As long as you pass - good enough. What is FAR MORE IMPORTANT is attitude, social skills and your overall presentation as a professional. At our company we NEVER ASK FOR TRANSCRIPTS. Waste of time.
So - have fun, go to partys, PASS - then go get a job. Employers will be far more interested that you juggled your course load with, say, volunteer time at something like Engineers Without Borders or the SUB Council. Shows more than just math skills.
(Some big companys do screen by grades - but personally I wouldn't work for a big company anymore - they suck…)
I have 21,474,850 rep points...
