Ishikawa information training fee? How much is Ishikawa software testing training?

I went to see Ishikawa's official website, but I didn't seem to write down the specific cost. Then I consulted online customer service, and she said that you can try it for free, and then decide to sign up when you are satisfied! I decided to be more human! Dear friends, you can also ask them more! I asked them a lot of questions and compared them with other training institutions!
