If doing modular training then I would highly recommend doing all elements that do not have a time restriction. Doing a section such as the ATPL theory before your hour building (which can take a fair few months - in my case, 12 months and still counting)...then its a waste of valuable time and may lead to undue pressure in order to complete the remaining parts.
If your on a badger arse budget like some of us then structuring your course in this way will benefit. If you have a wad of cash that will allow you to train full time modular then its a diffrent scenario.
How do you eat yours?
