Just took advise from Ben and try Triplebyte.
Before talking about my exp, I'm not a fan of quiz. I don't think it judges people's skills correctly. But I did it anyway. The result is my failure.
Hold there, this is the very interesting part. Even though the quiz seems plain, somehow the test actually works very well. It know correctly what I miss that even myself couldn't figure it out. I always knew that I miss something which prevent me to becoming a pro but never know what is it. Today, the test has pointed out exactly what I'm lack of. Triplebyte even gimme keywords for self digging. Man! As a self-learner, I only dream for a keyword to learn. I have no mentor, no academic guide and even no friend who give a damp about CS. So all I can learn is all from keywords and google it. Now I have some very well keywords, can't wait to google it. Triplebyte's even more generous by giving a really cool stuffs to learn.
Couldn't thank you enough Triplebyte and @ben
