Hello, my name is Alex.
You see, on april-june next year (I haven't got an exact date yet) I will have a test with the japanese embassy of my country. If I do good on the test and on the interviews, I might get a full university scholarship to japan. So I could really use some of your help since I tried a japanese course but it was just too goddamn slow and I learned in a day what I learned there in 2 months.

What I'm planning on doing right now is:
-RTK (30 kanji per day)
-Corresponding RTK deck + core 2k/6k optimized vocabulary deck (20-25 per day)
-Tae kim grammar and then manga guide to grammar (and then possibly DOJG)
-Reading native language plus listening
(besides all that I've got no problems in physics or math since I'm in the olympics in both so I think the test won't be a problem)

Please give me your advise if you have the time, thank you very much!

You didn't mention anything about the requirements of the test, but it sounds like a reasonable plan to me. Basically what I'm doing at a much slower pace. Bear in mind that to cover the material you mentioned that's about 5 hours of work per day including reviews, so plan accordingly. You sound pretty sharp, so you may shave a little time off here and there if your memory is better than average, but no matter how you slice it, or which method you choose, it's going to be a significant time investment to cover that much knowledge. But the curriculum is solid.

Thank you very much for the response yogert, you would say my pace is too slow?
Should I turn it up a notch?
I knew I'd have to make an effort and put a lot of time into it before getting in, so yeah I'm ready for it.

Like I said, you didn't mention what the requirements of the test would be, so I have no idea if that's enough. I think at your pace, you could get above an N3 level, but probably not N2. Of course I haven't passed either test, but I'm considering taking N3 in December with low expectations on passing. That's after studying around 90 minutes per day for almost 3 years come December. Of course my memory is sub-par, so you'll do a little better. If you haven't seen this post, there are further estimates for the amount of time it will take to study some of the materials in your list. I'm just giving you an idea how many hours is required to get to a certain proficiency, but I don't know what level will get you that scholarship. If you know what level of proficiency is expected, we may be able to give more specific advice.
