The Associative Laws say that it doesn't matter how we group the numbers (i.e. which we calculate first) ... ... when we add : (a + b) + c = a + (b + c). ... or when we multiply : (a Ã b) Ã c = a Ã (b Ã c).
To complete the PCT in two months (or less) you will need to average approximately 43.6 mi / 70.2 km per day (this was my longest day on trail).
Many CNA programs can be done in 2 weeks, though there are 8 week and semester-long courses, depending on where you get your training. Most PCT programs I've seen take at least a semester. You will have more lab hours and more clinical hours in a PCT course.
