It is fairly clear how to get your standard of language up to an A-level standard (exams taken at age 18 in the uk) due to clear syllabi and textbooks up to this standard. However, I find that past this standard there is no clear curriculum upon which to base your learning. This potentially causes a situation where you lack direction in learning.
What is the best way to structure your learning strategy in order to improve, in a language at a post A-level standard, your 1) reading ability and 2) listening ability.
Answers should be focused on self learners who also live outside of the country which uses the language.
