Sounds like a challenge. In my opinion, you'd need to be both dedicated and focused in order to do this, not to mention ambitious. You'd have to live for Kanji for those few months. I mean, it's possible - of course it's possible, but this task would require a strong will. Three months is an average time for a semester. I have eleven different subjects during that time and I am quite content. It's very diverse, keeps me occupied and learning different things. Last year, though, things were very different. I still had eleven subjects, just like this year, but I was practically ''living'' for one subject (it was very difficult and detailed). I'd managed, but I was under constant strain and pressure. I couldn't wait for it to be over and the rest of my subjects suffered. At times, the very thought of what awaits had me groaning.
