Hi, glad to hear that you are passionate about Architecture and Computing. I did my Masters in the Bartlett quite a while ago so I think my information might not be up to date. However, I think that most of the concept still applies for the Masters portfolio. For example, edit what you might show in the portfolio, eg. edit out the things that might not be your best work/might confuse people, strategically sequence the order in which you might show your work. Best of luck!
