I find that learning French is difficult in the first year or the first two years. And then it gets easier.
English, however, is very easy at the beginning, but when you start learning more advanced grammar it starts being more and more complicated.
As far as your test is concerned, the best thing to do would be to ask the examination center for a list of requirements - you will then know which tenses you need to master.
Because French hate when foreigners start to speak their language !!!
It's a common joke haha ...
But I have to pass the exam in Canada
I think they want more than 3 tenses
