There are two parts to this course. Part One will teach you the grammar rules that you'll need to know and some basic vocabulary. Part Two will expand your vocabulary.
I'm not currently working on this course but I check regularly if its popularity is growing. If I see that this is the case, then I will continue to enlarge it. If you see any mistakes or think that you have an alternative answer, please let me know here: https://community.memrise.com/t/40441
