at what point I can consider my self Intermediate level in French

I understand that level 1.1 - 1.15. Is a beginner level. Probably also 2.1... 3.1 At what level can I consider myself intermediate level? 4.1? 5.1..... At what level will I be able to call myself advance level?

It depends what levels you are talking about. If you mean the Common European Framework of Reference [A1 & A2 are beginner, B1 & B2 intermediate, C1 & C2 fluent], I'd say finishing all of Premium will take you in between A1 & A2, and finishing Premium Plus and Platinum will take you in between B1 & B2 (intermediate). You will *not* reach advanced level C1 & C2 (fluent) just by completing all the courses either on Rocket Languages or any other program. You will need either immersion or many, many hours of native conversation, and also additional grammar studies and more comprehensive practice with it. (The grammar taught on RL is more introductory or functional.) Here's a description for German-language learners, but the benchmark levels still apply: http://www.deutsch-als-fremdsprache.org/en/faq/323-what-does-language-level-a1-a2-b1-b2-c1-and-c2-mean.html

Personally, the difference between beginner, intermediate, and advanced, isn't important as I don't need to pass a French proficiency test. To me, studying another language should be an enjoyable experience and one in which I have the opportunity for exposure to another culture. Truly, the French have a beautiful culture. Unless we start RF with some knowledge of the language, to reach an intermediate level will take a lot of work and won't come in a month or two. My advice: Keep a steady pace, and get as much exposure to French as possible through RF, on the internet, and with a Francophone group in your community if possible. With perceverance, advancement will come.
