Welcome to the site. The way you plan to train is a good one. I did a similar thing way back. Had a long period off work, was available to fly every day for 6 weeks, except some weekends, and finished heli ppl in 5 weeks, mon to fri. You make much more progress with repetitive flying rather than an hour here and there every few weeks. It will save you some money too as less hours usually required doing it that way. It's more intensive and sinks in more for some.
I did the exam study during my course, usually at night in the guest house I stayed at, or whilst in the pub on a night time having my dinner and a pint.
If you get the exams out of the way earlier, it will help your knowledge when you come to fly and less to worry about.
Good luck whichever way you go about it.
