You write from 5 - 25 words on a page. Look at your list as often as possible. The more you look at it, the sooner you will learn the words. Look at the flashcards when you get time. Lists and flashcards are an effective method of learning words for most people.
Some people learn visually, others have to hear something in order to learn it.
If you're a visual learner, you have to see something to learn it. If you fall into this category, no use wasting time with oral vocabulary drills. Learning things by sound isn't your strong suit, so you should take advantage of your visual strengths. LOOK at your flashcards. Picture the words in your head.
