This is a user friendly app with a very convenient and fun environment for you to study and succeed in your exams. Using this modern way of studying you would no longer feel uncomfortable carrying your cards with you in your purse or pocket and you can study any where and at any time, whether it's in a nice cafe or while waiting for your appointment in a waiting room. Another nice advantage of this app is that after studying each portion you can take a multiple choice quiz and the system will automatically take record of the questions you missed on the quiz and saves them for your future review. You can also mark the cards that you feel you would need to spend more time studying or review right before taking the exam. Plus it's GREEN!Enjoy and Good Luck!Go Pink, Go Green!
