Hello, my name is Junjie Luo I’m a City College Freshman and this is my digital portfolio for my Writing for Engineering class. In my portfolio, I will show the assignments I’ve done this semester. This semester we have 4 major assignments and they are Lab Report Analysis, Technical Description, Engineering Proposal, and lastly the Self-Assessment Essay. I hope my work gives you guys a general idea of how each assignment is done and hope you guys can learn something from my work. > All Posts.
