Sorry if I am slightly thread drifting but consider the following.
The sad fact about this is the introduction of the JAA system in 2002 should have been the death of the integrated course. On the previous CAA system the self improver route needed 700 hours to upgrade the BCPL to the CPL.
The advantage of the integrated course (not sure what term was used then, CAP403?) prior to 2002 was it allowed a "full" CPL to be obtained at 200 hours, thus saving you the need to spend time in GA hour building. Therefore the expense of the integrated course over the self improver (you could say the CAA equivalent to JAA modular) had some justification. At that point prior to 2002 Oxfords main trade was mainly airline sponsored cadets from both the UK and international sources, so self funders at Oxford did exist but would be the minority.
With JAA allowing a full CPL to be obtained at 200 hours on the modular system then there was no good reason for the integrated course to exist.
The only thing which perpetuated the integrated course was a very clever marketing department from Oxford and trading on the past reputation.
