If you want to memorize English words, I would recommend using flashcards. One program that works great for that is Anki. You can download that from http://ankisrs.net/. Another good one is Memrise, which can be found at memrise.com

Hi, my name is Uri Quintal. I am an ESL and Spanish teacher graduated from the Arizona State University in the United States. I offer some basic lessons for non-native English speakers in order to help students not only to speak another language but to think and dream in another language for a very cheap price. Please feel free to contact me if you are interested. I am on skype as: Uriquintal. Have a nice day! :)
