This is EXACTLY how it went for me when I moved from a Physics to an Electronics Engineering degree at University.

Also, the trying to understand how the various circuits worked from the point of view of “electrons moving” was a hard to overcome early tendency (even simple things like LC circuits, for example, are only really understandable as ressonant stable states and for complex circuits you really have to go higher levels than “electrons” to be able to understand then in any reasonable amount of time).

On the upside when we got to things like how tunnel effect diodes worked, the whole thing was just obvious because of having had an introduction to Quantum Mechanics in the Physics degree.
