Hi, I just want to confirm how many basic levels are on French course?
Each skill has 5 Crowns, which when added up amount to over 300+ Crowns in total for most of the target languages on Duolingo. The entire French course, imo, is "basic french", so you are looking at over 300 'levels' in total.
That is true, except if you have bought Flirting or Idioms, which only have one crown each.
You can use your (unofficial) progress page to see how many skills and crown levels there are in your tree: https://www.duome.eu/Karen926750/progress
As boricano3 says, the whole course is basic.
XP levels are the same for all languages. You'll find more information in this thread: https://forum.duolingo.com/comment/2261330/XP-needed-per-level
I think there are two versions of the French course (the newer, longer one is being rolled out now). So it is impossible to say how many skills a French tree has - but you can click your "Home" tab and count the circles and see how many skills your tree has.
You can get up to level 5 on every skill, or circle.
There is another kind of level on Duolingo, called the "XP Level". You are on level 5 right now. The more points you earn, the higher your level. 25 is the highest level there is.
