Ok, I supposed, but I don't know why they put you Hold and at the same time recommend you to take that program
Why? because the preprogram begins on January (until March), a few weeks before start the program. So, you must wait until the last time for a response??
In my case I had the same situation, put Hold and take de preprogram course, but if the situation is like I described before, I think to leave the application process. I know a lot people who were accepted together to suggestion to take the preprogram course.
