This is an excellent course, with lessons building on each other, just the right amount of new vocabulary and very interesting cultural and linguistic notes.
My only complaint is the uncertainty of the technology. Sometimes even though I am logged in, I am not able to access the lessons, while the sound files do not play all the time. I suspect the compatibility might be related to browsers on a Mac, because ever since I have switched to using my office PC, things have become better.
I use a Mac and have no problems. Yes, it happens once in a while that the password is not recognised, but then you can simply click on “forgot password” and select a new one. Please also keep in mind that this essentially a one person business.
