Public universities are free of tuition, and the remaining differences can be ignored. But you can't get into these universities if you fail the language test. Even if you have enough language tests, you may not be admitted. I can tell you responsibly that none of the domestic intermediaries can run these schools. Even the schools they can run, such as clermont, can only give you a pre-admission notice. You can only use it to get a visa. After the visa is a piece of waste paper, it doesn't mean that you have been admitted to the school. After studying in France, you must continue to take the TCF exam, and you can only apply to the school if your test score reaches B2(450 points), but whether you can be admitted to the school depends on your luck. Therefore, I suggest that you don't choose public schools for the petty advantages of free tuition, and then follow the old path of many students. Another point is that you can't find a job after graduating from a public university. You should be careful not to listen to the hype of the intermediary, because your contract with the intermediary will basically end within three months after you arrive in France, but it will be a year later if you can enter the major, but it doesn't matter if you find that you have been cheated and can't enter the major after one year!
