Description
Here at BRA we take great pride in our award winning Architecture program. We have educated students that become masters of this art form and have delivered some of the greatest architects in the world. Some of the most awarded buildings out there are made by BRA graduates.
The program builds upon the old masters of architecture and gives the students visual and mathematical skills to conquer the world. For most students, this course will be a huge challenge, for the right students, it will be their dream come true.
Facts
Only a few students will be able to follow this course. And, therefore, a series of tests will be held in order to find the right candidates.
If you feel Da Vinci was a bit on the uneducated side, this might just be the place for you.
Requirements: a pencil, a sharpener and some Legos.
Comments
This class rocks. I learned how to build my own dam the first week! Some lectures are a bit difficult to understand (Pyramids for Dummies was one of these), but overall, I really liked this class.
Life at Campus
We have sports and educational clubs that will suit most students. Campus is a large area with a huge park as the center point. There is easy access to all accommodations and everything has been re-vamped over the last two years. So, if you like football, soccer, rocket science or anything in between, we got something for you. If you want to know more about campus life, you can call one of our trained students and they will be glad to help in any way they can.
