To tell the truth, I really feel cheated; It is said that there are teachers answering questions online, and many teachers who actually answer questions have no practical experience; I promised a lot of things when I paid the money, and my attitude was good. My attitude changed quickly after I paid the money. And their online Q&A only answers the content of the video course. For example, they talked about the usage of two functions in C language alone, but if the video course didn't explain how to use these two functions together, they wouldn't answer the questions.
If you want to find a good job through their courses, you must have very strong self-study ability.
What they say to ensure employment is to pass their assessment. If your self-study ability is not strong, it will be difficult for you to pass the examination.
