I would not recommend it Pilot16. I did the residential ATPL's at LMU and it took up most of my time for 6 or 7 months. Lessons are from Monday to Friday 0900 to 1600 if I recall; and I had to do at least 3 hours a night just to keep up with the workload, sometimes more. Plenty of the weekend is also eaten up by studies.
I've had the pleasure of doing a Pure and Applied Maths A-Level (in the past) so I know how much time that takes too.
Sorry but if you're residential, the ATPL's will consume your life for the duration.
Good luck!
