Hi Viktor. Have you ever heard of Anki? You can try that. As Sevilay recommended already, Quizlet as well

paper ! he he .. nice and easy.. actually, my teacher condenses everything together for me that I have learned that day and puts it in the chat box on skype. I then copy that to google docs and I have a running record easy to find and review everything learned. I hope that idea is useful for you.

MemRise is a great memorization Tool.

Anki is great. Good luck!
