First, it is easy to change majors.
In the application stage, most students will pay more attention to the school, and will put the professional choice behind when choosing. After all, unsuitable majors are easier to change majors than schools.
However, it should be noted that French universities are very strict in reviewing students' applications for changing majors. If you want to apply, you need to do very well in your major in order to prove your learning ability.
Second, it is easy to graduate from a public university.
Studying in a French school is not as simple as graduating from school, because the school implements a policy of lenient entry and strict exit. If you can't meet the graduation requirements, then everyone can only continue reading.
So don't think that everything will be fine if you enter a public university, but you should study hard to get better grades and graduate smoothly, so as to complete the whole study abroad.
Third, preparatory courses and language classes are the same thing.
Almost all students applying to French universities need to receive a buffer period of study before they formally enter the university, which may be language training or professional familiarity, and there is a distinction between preparatory courses and language classes.
Everyone should distinguish the difference between the two. Private language classes aim at language training. Preparatory course is a professional training, in which there will also be language teaching, but the focus is still on the specialty.
You don't need to learn French to teach in English.
At present, many funny majors in France have set up English teaching, but even if English teaching is chosen, we can't ignore French learning, because we still need to be exposed to French in our daily life.
And after everyone leaves the classroom, the communication with classmates and professors will still be dominated by French. What's more, learning another language is of great benefit to everyone.
