I looked into the school you mentioned. It seemed reasonable for a Pastry diploma as each one was about 2500 per semester. However, most programs will teach the same things on paper. Find out how long you are in class doing hands on work and if you have the chance to apply that knowledge at catering events on/off campus or if they have a restaurant.
Also, research who the teachers are and where they worked.
Lastly, work for someone while you attend school. At least 20 hrs per week.
