I am an aspirant in our Diocese. We had two years to get our pre formation requirements completed, these courses could either be taken on-line or through Saturday courses. Once accepted into the program, it takes five years to ordination. We have Saturday all-day classes, most of which are done through distance learning. Each course is four weeks, we meet every other Saturday and we do not have classes in the summer. We also have formation days and attend an annual retreat.
One thing to keep in mind is that the time I spend on studying and homework is the same amount of time that I was spending learning and studying on my own. Now there is more structure to my learning and I have nine brothers who are on the same journey, a journey that I am enjoying. Not to mention that I am answering the call of the Lord.
