Hi, I have two questions about Kaplan Q-trainer: 1) Are the Q-trainer and Q-bank same thing? 2) I got a Q-trainer from a friend, but it is 2003 edition. Is it the same as the up-of-date edition? I'm wondering I could use it for my study or I have to purchase a new one. Anybody could give me any advice? Your kindly help will be highly appreciated!
