Is this link good enough to check for the PR application or there are other things as well?

In the Section Two of the self assesment test, if you get 7.0 on IELTS then we will get full 16 points right?

What about the french section " How can I get the Basic Profficiency? Just knowing very very basic things will be enough or you need some course on that?

What about the experience section? I had worked on one software company. Basically we started that company and everybody is here in states. So there is no physical existence of the company but in paper it still exists. So will that experience works or I should get some fake experience from the existing companies?

Also I had worked as a GA for one professor. So will that experience also counts?
