Welcome to the 2I
This is your second year of learning the English language.
What is the best way to keep learning a language and what do you have to learn?
Learning the pronunciation of a language is a very important part of your studies. If you want to speak a language well, review the pronunciation regularly. There are many exercices to do it!
Building up your vocabulary in a foreign language can take many years. Learning words in context is probably the most effective way to do this.
You could also try to learn words in a more systematic way - perhaps a certain number of words every day.
Familiarity with the grammar of a language enables you to understand it, and also to construct your own phrases and sentences.
Review all grammar exercices and never hesitate to ask questions during the lessons.
