First of all, compared with the college entrance examination, self-study is much less difficult, so I suggest you read books by yourself first, and recommend you to read such classic works as The Art of Software Testing. Then there are training institutions, which can help you contact employment companies, but your actual training and learning are basically the foundation, which can only be regarded as an introduction. If you want to improve, you have to study by yourself. The cost of training institutions is generally more than 10 thousand yuan.
