Typically, due to a bias for grammar and translation in study methods, language skills don’t grow evenly, the weak point being speaking.
That’s the focus of my lessons.

For example, if you’ve already gone through an intermediate grammar book but can barely introduce yourself, start from Lesson 1.
You can set your level at any time on your dashboard. That will change the lessons shown on the page so that you know which ones you need to take.
