Number of Characters Taught?
Does anyone know the exact number of Chinese characters covered in the Duolingo course? I'm excited because I just finished the tree today (everything to level 1 at least, with several 2s and 3s). I also finished HelloChinese last week. (That was pretty cool...your screen goes black and then you see and hear fireworks!) Of course, this just means the real work goes on in both courses but I'm really excited! And curious as to how many characters were introduced in the entire course.
Not really related to your question, but just for your information:
If you have finished the tree on level 1 (or even level 2), you might consider starting to read "real" stuff:
http://mandarincompanion.com/ (Not free. Start with the Sherlock Holmes story which is quite easy)
http://chinesereadingpractice.com/ (You can filter the texts by level)
http://www-personal.umich.edu/%7Edporter/sampler/sampler.html (more difficult texts)
This is an extremely useful website for reading:
Sometimes, you will notice that you cannot understand a sentence although you know all words in it. It might be because you don't know the particular grammar pattern used in that sentence. Check this website in that case:
I don't know for the number of characters but congratulations for your Chinese(tree +Hello Chinese).
Did you try Chinese on Memrise too?
I use Hello Chinese too, Memrise and some Chinese interesting videos on YouTube.
I found the website that claims how much you can read with how many characters.
I wonder what the source is.
I'm not sure about the "read 75% with 500 characters" statistic, but even if you recognize 75% of the characters, you won't understand 75% of what is being said. You will recognize characters for "and", "but", etc. while not knowing a lot of what they are talking about. Plus of course there may be many words where although you recognize one of the characters in the word you don't know what the word is. Anyway I'll let you know how many characters you need to be comfortable with reading if I ever get there. :-)
