I have to say I haven't found it easy.
I'm only at 873 after 9 months, and this is my second time
The first time was a few years ago and I wasn't using any form of SRS, so I hit a wall at about 380 kanji. I just spent so much time reviewing that I couldn't add any new kanji.
I ended up giving up.
Then last year I found this site, and it was
exactly what I wanted.
I started up again in May. The first 300 were easy and only took a few weeks, but after that I just couldn't seem to make much progress.
I was reviewing regularly, but I wouldn't add any new kanji till I got 100% correct on the old ones. I found it hard to make the stories, especially for abstract kanji.
I don't have a lot of spare time, and had some things going on last year, but I guess I also doubted the technique a bit. So I often got "stuck" for weeks at a time, and I only got to 600 by January. That's less than 35 a month (not counting the first 300)!
I was seriously doubting whether I would ever be able to finish.
Recently I've made some changes:
-
make time every day for review and learning new kanji
- use the stories on this site first, usually there will be something good!
- make sure I really visualize the image, rather than relying on word association
- don't stop adding new kanji because you failed some of the previous ones
- clear my failed list every day, re-learning them by looking at the stories again,
even if I'm not that confident of the story, just keep failing and relearning
The good news is that
it's working!

I've been adding 10+ kanji every day, and now add more in a week than I did in 3 months last year! I was a bit worried that adding kanji too fast would lead to a big drop-off in my recall, but so far I'm still at 85-100% each day.
Even though I'm less than half way through, I'm finally confident that I can finish RTK. I'm aiming to finish by May - I have to make it in less than 1 year!
So for those of you having trouble, my advice is look at ways to improve your techniques, and most importantly
stick with it!
