I talked to a Self Learning student (who claims to be at N1) and he told me this. Is this even possible? Or its an ridiculous exaggeration?

"I took Heisig's advice to the heart and adopted the divide and conquer strategy. I finished RTK, and then completed one of those 1000 words or so vocab decks. I ditched readings and listening all together after that, just learning maximum vocabulary a day using my Kanji mnemonics (I also added New Kanji meanings since Heisig's keywords stopped working after a while). I did grammar on side too. In 7 months, from total noob, I had done over 10 ,000 words without readings, and about N3 - N2 grammar. Then probably for 4-5 months (busy because of family), I just reviewed the anki decks, read articles (like nhk easy) , easy Visual Novels , Stories (adding unknown words to Anki). After that, I only paid attention to readings while watching anime with subtitles, visual novels and making a mental note (no Anki), and they came automatically to me. "
