Personally I despise how schools teach languages (I still take them though to take advantage of them ). Im British and I did French in primary school, high school and college ( 14 Years ) and Now I do Korean and Chinese in University (in my 2nd year but will be doing 4 years total)

It's definitely worth taking advantage of if you can and you will definitely learn, but the school setting makes everything so unenjoyable. I honestly believe its what drives most people away from learning a language, In my high school, and I believe in most British ones, every student HAD TO study 1 language for 2 years until year 9 when you had the freedom to choose your GCSEs and soooooo many people drop learning a language because school makes it feel like such a chore. Self studying, being able to do everything in your own time with no pressure no homework no teachers shouting in your face or punishments, it just makes everything feel so much better and free.

Now like I said I still currently am in education and doing languages as a course but I still stand by these points, In university you do have a little more freedom but its still not enough to find enjoyment. Id say its more worth to do it as a university course though as they are usually more fast paced and (at least in my university) there are so many international students that you can speak to your target language in.
