English? English Lit? English lang?

So, time has come, i'm giving security up and going to university...
Although, i left school early, and don't have the right requirements.

i have all the requirements planned for this year coming.

although!
the university of my choice ( to start 2017) has said, english grade a-c IS NOT required, although it will strengthen my application, also help me get back into studying.

so i was looking online for different english courses etc..

But there three for english...
English
English literature
English Language

i just assumed there would just be one, not three?

So my question to you guys is, would i have to get all three?
or just the English?

Thanks
