I am working 9 to 5 and taking a week per exam. Already done all ( R/T theory + Practical also)except Flight planning. Some guys might find it a bit slow but with work and other family commitments I think that I will be overstressing myself unnecessarily if try to give an exam every fourth or fifth day.
Remember that PPL theory will set momentum and basic foundations for CPL/ATPL theory. So take your own time but do it well and dont forget to go thru confuser only when you have read the whole subject thouroughly.
