"Grouped by topic, easy to carry"
These flash cards are grouped by topic (e.g., bank/money, animals, sports/entertainment, school, travel/directions), which is convenient when you're studying a specific topic. Other than a section of "useful adjectives," if you want to study particular parts of speech, you have to separate them out. Not a big inconvenience, though. I would have liked the verbs to indicate if they're strong/weak, irregular, and so on, but the reverse of the glossy side of the card is suitable to write that information on.
