I think so many people forget how difficult it is to actively study and get stuff into your brain.
When I did an extra course a couple years ago I had literally forgotten what worked for me. For me is writing down key words essential, and soft music without lyrics.
Distraction is also a challenge. For me it worked starting the day with studying. During the day my head will always drift off towards 1001 other things :)
Yes it depends really of you! I can also listen to music but with lyrics, but not in French otherwise I'm too distracted. The most important is to find your work method, after you found it, it's a piece of cake! Thank you for your comment!
