Let's talk about the content first: sort out all the assignments in the university for four years, and choose what you think is better in each period. Mainly packaging, books, posters, corporate image, graduation design and other finished products, with a small amount of basic course assignments. If it's difficult to make a book by doing few things, you need to make up some by yourself. We don't consider studying abroad here, but only looking for a job after graduation. You'd better fill in the contents close to commercial design, such as DM sheets of real estate and cars, pages of fashion magazines, packaging of daily necessities, company LOGO, corporate brochure, recipes, etc. And let others see where your level is as much as possible.
