I plan on re-studying French and getting back to B1 level proficiency (intemediate)
I'm a weak A2 now and I know there are a few free courses 1 online to get to C1 level then may do an intensive course for a month in France at a language school.
I've also read Fluent Forever and Fluent in 3 months.
My plan is to do this by August/September this year (2020)
Is this realistic and achievable?
