I took a year to do mine with a full-time job, hour building, the odd gig and caring for a terminally ill father. Didn't bother with housework in that time though
After obtaining your PPL, you'll need to build approx another 100 hours so you use that time studying. Whilst you can, you'd be unwise to start a CPL flying course before you've passed all the exams.
