In my opinion, I think the best way to study new words as vocabulary is write it down on the sticker and stick it every where in your room or your house as much as possible. I tried that way when i began to study English. I wrote the words, the meaning, practice pronounce those words everywhere and everytime. More over, you should take English class with the foreigner teacher, I'm pretty sure your speaking skill will improve a lots. When you talk with your teacher about new words, it would be easier to remember those words than you study by yourself. And remember that if you do not know how to pronouce, you can use internet or electronic dictionary to check them. Hope my answer helps your skill.
