Daria,
You only get one shot get getting through all the phases with acceptable results, don't make it any harder than it needs to be. I completed training modular style by studying and training in my free time by getting up at silly o'clock, managing family life and holding down a demanding career. How hard you ended up working isn't really all that relevant, how well you did is. I'm not meaning to imply probable failure, but from my experience I can't recommend your approach.
