You could try the Canon-Dovahzul Memrise Course, in the "Learn" section. That's a pretty good way to learn it, if you spend like 5 minutes a day on it, or even less, you may start to memorize words very easily and fast. An app exists too, in order to access the course even faster and doing it in the bus or anything. I did it, and it helps really.
