Kamin you just need to settle yourself down, try and avoid doing other things (suddenly cleaning your windows may seem much more thrilling), turn of tv and radio, make a big jug of coffee, get lots of plain paper and coloured pens and try to visualise what you need to learn.
I found it helps to be writing it down. Also use the system of thinking of an image for words you need to remember, like "Richard of York gave battle in vain" which reminds us of the colours of the rainbow.
There is a word for this beginning with M but I forget.
