If you teach yourself, it may take 2 weeks to learn simple drawing and typesetting. After all, cdr is used for typesetting. To really master all the contents inside, you need a professional teacher to teach, maybe less than a month! The key is to see what you are learning CDR for. I hope the answer is helpful to everyone. If you have any questions, you can ask them on the self-study website, and I will try my best to help you solve them.
