As for me, it takes much more time.
I'm a full time student too, though I don't have so much spare time inbetween.
Though you might think I've got a reasonably good memory, for I study laws.
But for people who don't read Japanese texts every day, like myself, it's kind of time consuming to study Kanji. You need a context. Even using Heisig.
If you read texts every day and spend a lot of time every day you might be able to learn a lot of Kanji, maybe even 50 a day. Though trust me, you will forget them. You defenitely will if you don't repeat them until they are totally fortified in you mind. So you can learn 1500 Kanji easily in 5 weeks, though you will have forgotten most of the first 1000 if you don't fortify the stories you made up and if you don't repeat them every once in a while. ALSO and that is what most people I know forget: You need to repeat them the other way round as well, from Kanji to meaning. That strengthens your memory and your ability to read fast and recognize fast which ist even more important than being able to write in these times.
I do it like learning 200 new Kanji then repeating all kanji I've learnt before. I'm at 1700 now and you might notice that this takes quite an amount of time to repeat. Like 2 or 3 days. It takes me like 20 seconds per Kanji I remember and 3 or so minutes per Kanji I don't remember.
I have just finished (2 days ago) repeating 1600 Kanji and it took me a week (I didn't have too much time) and I realized that I finally know like 480 of the first 500, 440 of the second 500 but only like 300 of the third 500 and only 40 of the last 100. That is kind of depressing. But normal, as I think. For every time I repeat the Kanji about 20% of the remaining Kanji are remembered in long term memory. I suppose I will never remember all 2042 that way, but nearly. And when I start reading texts a lot that doesn't matter anymore.
As for me, only 342 Kanji to go! I just started to repeat Kanji 1600 - 1700 for the first time.
BUT THIS PAGE IS GREAT! It is much faster to study here!!! I learnt over 1600 Kanji without this page but the last 100 Kanji were so fast! Even though only about 70 of those fit with the keywords on this page.
Sorry for the long talk, but please stay realistic. As I said, I suppose I got quite a nice memory and take my time to create stories, but I still forget plenty. We all can do it! But it takes more time than Heisig says, I'm totally convinced of that!
Otherwise, if you got a perfect memory.....
Sincerely,
Ben
P.s.: Oh and as rgravina said: I sometimes read short stories in Japanese or some books and finally I realized that I know like 99% of the Kanji!! Not the readings, yet, but the Kanji. (and how about the Kanji I haven't learnt yet? Easy: I know about 100 of those already because I have studied lots of Kanji, like 1000, before I started Heisig, but only readings, NO meanings, which is why I am still stuck to Heisig, but am able to read a lot already

But even without that I 'know' most of the Kanji already. It's so great to look and recognize all of them!! You know, many people, even on these forums said: Oh man you need about 4000 Kanji to read proper Japanese and that is more than, sorry, ***** bullshit. Ppl who say that don't know a shit and just want to demotivate you. I can already, with 1000 (!) Kanji, read magazines, books and manga, even newspapers mostly stick to the Jouyou-kanji in general (but they are too tiresome for me to read yet). Learn your 2042 Kanji and you're pretty pretty well off!! Only, you need a nice vocabulary, but that is about all, learning kun-yomi is easy. Some more Kanji than 2000 only if you want to study in Japan or especially if you want to read classical literature or specialized texts. 2000 rocks!!)
Sorry again for talking long, but I just wanted to utter that, especially after reading such nonsense on these forums! HAVE FUN!
