Hello there,
I hope you are doing well, I assume from your question that you are very much interested to learn a new language. The basic thing about learning a new language is to communicate freely without causing misunderstandings. Taking a bachelor course in a language you aren't much known too can be abit difficult.
Some colleges might start from the very basic others may not do so and only brush off on the important stuff. This can vary from college to college and depending on the language that is required to be thought. A simple example I can give you of English. During my BSC the subject of English was through to us in brief and how to apply it , while writing or speaking. You can say it was more inclined to spoken English. But if you are trying for language like French or German they will start with the basics. Not necessarily that they may cover everything but the course will aid you a lot. As they say something is better than nothing. My suggestion to you is that go and check with the college you wish to admit and see what is being thought. The rest you will have to contribute your share of efforts too. But if you are doing pure bachelor's degree in a particular language than yes they will teach you from the basics.
Hope this helps.
