Well, I’m going to go against the flow. I studied electrical and electronic engineering and I found it invaluable in my career, giving my an early start as a technical trainer and then onwards and upwards.
But I was rubbish on the degree course, especially the maths, but I got a great overview of engineering and especially control systems. Stumbled out of the far end of the course with a 3rd.
Comparing the ATPLs to a degree level of knowledge is a bit pointless because degrees have wildly different complexity. Overall, I’d say more than A levels but quite a bit below a Degree. Unless that degree is in some totally
discipline (e.g. any of the Marxist indoctrination fields).
