On the Integrated course you will be exempt from doing the PPL and will also get a reduction in the hours required to qualify for your license. Modular is done at your own pace. You decide when u wanna start. Integrated everything comes at you pretty quickly and is more intense. Modular can be that way also if you want it to be (by doing everything straight away one after the other) but usually modular students spread things out over a bigger time frame. Bottom line with modular is you do what suits you when it best suits you.
