Supermemo 2004 - my main tool for learning and creativity

If you learn any foreign languages, you have to face remembering thousands of new words.
My vocabulary count remebered by Supermemo is 18,000.
I use the newest version SuperMemo 2004. It allows not only to learn vocabulary but also to read incrementally (it means reading scores of articles, mostly web-based, at a one time).
I've been using this program for 9 years, since it was a DOS-version 6. I've spent a lot time with this program, but I'm not sure if it's been right. It became a very strong habit.
I was preparing for my exams in psychology using this program which is not the best way at all. It only resulted in huge collection of psychology (in Polish) but not so good marks on the exams - preparation of this collection took most of the time needed for the exam study.
Recently, I've become beta-tester of this program. This distinction was a reward for my faithfullnes throughout all these years. I must confess that this program works best (for me) for word pair learning and that all other inventions are a little bit ineffective. For other uses I much prefer Microsoft OneNote which I will describe later.
