If you purchased the kit last year, you'll find that you'll still be using those items and will continue to use them throughout your architectural education. Most of the money you spend will be on materials for your projects.
3-year Grad Students
The cost for 3-year graduate students varies depending upon what tools and materials you may have prior to entering the program from your undergraduate degree. The cost of each project can also vary from student to student depending on the materials they choose to design with and the amount of exploration you want to do using different materials.
