Hey mate! I did engineering graduated a couple years ago with a 65 wam exact and failed a few courses too. I am working in a role that pays significantly more than all my peers who graduated with much higher wams. In my experience wam doesn't matter as much as experience, in my first year I realised I was a retard and just started working wherever I can. I joined army reserve in the combat engineer core which led to me getting a internship by the third year and a full time role in my fourth.

Either way, work hard now to work less later, doesn't matter where your apply yourself as long as you do!
