I Did a BTEC in Music Technology and an A-Level in Music. The A-Level in Music was probably more useful than the Music Tech course. I have found Music Theory to be a huge advantage in production. The majority of what I learned on the Tech course was OK but I learned the most by getting a DAW and just learning it myself at home and talking to other producers. I can’t say I learned nothing, but yeah, the most of it I learned myself just through Tutorials and trial and error.
