there are lots of methods you can use in order to memorize vocabularies.
I always read the vocabs 2 or 3 times from on the note. then , I alwys right the new ones on a narrow piece of paper ( the one i can carry every where) and I keep that every where with my self . as using the bus to university, between the commercial advertisements during the movies, and even when i'm on the way going to the cinema or restaurant with my friends.
use this method .it WILL work.
these papers are not heavy. A SINGLE PIECE OF PAPER that you can carry every where.
but one of my brothers always writes everything when he wants to memorize .it is a good way but I'm not so eager to use that.
But by the way , you can use one of these two methods or try to find YOUR OWN WAY .
hope it helps
