Nairna, I'll be honest, I have no idea what you said in your post.
Silentstriker, my understanding is that when the applications are reviewed, and students start getting accepted, they fill the RMC slots in the ROTP program first, and then once all the RMC slots are full they will start to fill the civi university slots. However, they will put you straight into civi uni if you select that as your first choice, and there is a greater need for officers in the canadian forces then there are slots at RMC. That is to say, (and this is ONLY FROM MY UNDERSTANDING, not sure if its fact), they fill RMC first with people who have RMC as their first choice. Then, they offer the ROTP to civi uni student applicants who a) chose civi uni as their first choice, or b) didn't make it in with the group that chose RMC as number 1. If you wanted to be certain on this, it would be best to contact a recruiter, as I am sure they would have more information.
However, you mention that if you were offered RMC, you would take it. So, it is HIGHLY recommended that you put on your application that you wish to attend RMC, but then list it as your second choice (or third, if there are two civi schools you would prefer over RMC). This way, you are maximizing the number of ROTP slots that you can potentially fill, while still indicating what you prefer.
I hope that answered your question (and possibly yours nairna), and I hope all goes well with your application.
