I started doing level 1, lesson 1, just to see how the site worked. Actually my level is upper-intermediate. But now I can't get out of this basic level. All the subsequent lessons are padlocked. How do we move about between levels and topics?
For this to work for me, I would need to be able to move rapidly between levels and topics. For example, one day I might want to revise some really basic stuff, the next day I might like to try some advanced topics. I don't want to have to complete every basic lesson before I am allowed to try the more advanced lessons. Apart from this, the site looks good, it just needs more flexibility.
