I've been working in mining for 6 years now, I managed to acquire a National Diploma in electrical engineering (cum laude) and I'm currently pursuing a BTech. I however do not want to work as a mine engineer, it is more maintenance management in my opinion than engineering design. Given that age is no longer on my side (I'm 25), is there any chance that I could break into the design world with a mere BTech? My strengths are power electronics, analog/digital controls and electrical machines.
