There are lots of differences between Integrated and Modular which you do not yet seem to understand. Read them up and you will find why Integrated is always more expensive.
Why don't you highlight those difference?
In the real world, the majority of the time it costs more to buy flexibility. People pay a a premium for doing things in stages over a longer period of time, around work/life/financial circumstances. Modular is much more expensive than "Integrated". In the world of aviation it's the other way around! Why? Well I think you answered that with this line:
Is that why Integrated graduates have a higher chance of getting a job on average than modular??
That's what your paying for my friend!
If the age of people who done/are doing/are thinking of doing an integrated course was correlated with age, it would prove a thing or two!
