The computer of Beijing University of Technology is still good, and it is not difficult to test. Just cross the border. When preparing for the postgraduate entrance examination, I only learned a little language, which is only the foundation, not to mention which major is suitable for studying computer. You can read books on the internet, databases and other places. See what you are interested in. There are many detailed instructions in the computer class. If the color is weak, don't make computer images, and everything else is fine. You can look at the enrollment professional catalogue of the school you are interested in.
