I also have an Aero eng degree and ATPL theories.
The depth of knowledge required for the ATPL's wont vex a man of your caliber...... But the Volume may.... tons of arbitrary garbage that have to be memorised for the exam... then forgotton!
At least the exams are all in English now...
I remember Ops Question

Do you?

B/. The moon
C/. Always check tanks for contamination
