Yo, Yes I finished allmost 2 weeks ago. In 3 months and 1 day, working 8hs/day.
It was a lot of pain, and not everything went acording to the plan. In the beggining I tought I would finish RTK in a month, but it took 2 more.

You can sure finish RTK before december. I do not recomend to aim lower than that. You probably can do much better than me, as you have a great memory.

But beware, after finishing RTK you wont be able to read any japanese at all.

So, if you wana impress anyone, fit learning actual japanese in your schedule. RTK is not impressive to japanese people. They will tell you that "jyozu desu ne" crap and laught at you behind your back for not being able to read what you write.

But you'll feel the power of RTK while learning japanese. And you'll have the confidence boost of having dominated the 2042 kanji beforehand.

I had the experience of studying japanese without doing RTK before. Over that I'll just say today I enjoy to be able to study japanese with good input, instead of crappy textbook input.

Ah, sorry about that ^_^'
Work hard and keep us informed of your findings!

Today I finished the hugely-large LESSON 23!!! Cake. So as of now, I am on frame number 766 and it has been eleven days. Average of ~70 kanji per day. To meet my "deadline" of August 17, I need to add ~80 kanji per day. My overall retention rate is still above 98%, if I recall correctly, so no trouble there. My reviews for the last few days have been in the 130 range. This weekend I plan on doing some *serious* kanji studying, maybe even 8 hours a day or more, so I expect my daily requirement to come down quite a bit, which is cool. I know tomorrow I plan on finishing lesson 25, which would be about the same number of kanji as today. Also, I'll start on Pimsluer if I feel up to it, but the German one bored me to tears.

So overall it's been pretty easy so far, and I'm still having fun with it. And It's going to feel so good when I finish!
