I've just finished Newbie lessons (up to lesson 80) and before I go on to the Beginner series I'm reviewing everything I've learnt so far, going back through the PDF's and making notes for myself to help me remember everything. I think I've got a pretty good grip on the basics of Japanese now, but I want a book/website/audiobook/anything that will test my knowledge. Sentence structure, vocab, grammar, kanji etc. - it's the best way to make sure it's all sunk in! Anyone able to recommend something that will ask questions and test me?
Also, as I said above I'm looking to go onto the beginner series now but the start of the Beginner series has already been covered in Newbie. Any ideas where I should start now? Many thanks.
