After I finished my Chemical Engineering degree at RMC, I found that I wanted more of the history and politics courses... so I enrolled in the BMASc at RMC, I really don't need it but it's mostly by personal interest...
I got an ILP approved and am currently doing one course each semester. Like Ammotech said, you basically choose your own course load. I find that one course is very manageable with work and I find that most teachers are very understanding of military life in general and most of the time, will gladly accommodate someone if he needs a little more time to submit assignment or do exams. Being in the navy, I had more than once needed a modification of the exam schedule to do the exam while I was ashore in Halifax and never had to fight or complain for such a thing, everything was handled smoothly, it was a question of one or two emails.
I have to agree with the lack of info on the finals but most teachers, if asked, will gladly go over the format of the exam. In general, for the assignment, I find that the essay questions are generally quite vague but on the other side, I find that the teachers will accept pretty much anything if it is well written with a solid and logic argumentation. I even once or twice asked to write about a different subject than the required one because I taught the given subject was quite boring. Again, it you substantiate your opinion and give the prof the angle you want to use to tackle your subject, most of them are very happy to oblige and it provides them with something different to read.
To conclude this part, you are your best teacher, you can either do the minimum to pass and get a check in the box or you can take charge of your education and explore the areas of the subject that really interest you, it's all up to you...
As for operations, I was able to complete a course while I was on deployment in Haiti during OP Hestia, it was very challenging having to study while doing the operation and thinking back I think it was plain crazy but on another aspect, it forced me to think about something else. Being on a ship, I know access to internet and study spaces is probably easier than during any land operations... For military courses, I guess it depends what kind of courses you're doing, I probably would not attempt doing a university course during a military course that requires spending any extended period of time in the field... On the plus side, at RMC, but only for operational reasons, (not sure it a last minute military course goes into that category) they allow you to drop the course without any impact on your academic history.
Of course, this is all from personal experience and yours may vary
