You haven't figured out the nature of the school. Training schools do not learn cultural courses, but mainly focus on practical ability to solve practical problems, rather than theoretical courses of cultural courses in colleges and universities. Education or diploma generally refers to this category, and training schools do not have cultural courses, of course, there is no diploma, so a diploma is proof of culture. So you have to distinguish clearly. But for fashion design, a diploma doesn't mean ability.

As for which courses there are, there is no uniform standard, because the teaching quality of each training school is different, unlike the textbooks of colleges and universities, which are uniformly stipulated by the state. It can only be said that the training schools mainly focus on professional courses, not cultural courses, so of course there is no special requirement. But relatively speaking, if you want to learn, in addition to the excellent teaching quality of the school, your own learning process will be hard, so you should be prepared. Not as loose as colleges and universities.

During the study, you can also use some professional and practical reference books to strengthen your lack of practical system knowledge. If you read a book, you can learn it as the basic accumulation and core of clothing design (clothing structure design, also known as clothing pattern or clothing pattern). Teacher Gao Hong's basic introductory reference book, Clothing Structure Design and Its Application, is mainly practical. 139 yuan. If this book can be digested, the Complete Works of Clothing Factory Patterns can be better merged, which is also 139 yuan. It is practical, not those theoretical books that cost tens of dollars in college. It will be of practical help to your future formal study and future work. You can go to Baidu to look at the encyclopedias of these two books.
