It's alright for refreshing your memory on terms and concepts (if you're just killing time) but not useful for active studying. Some issues: spelling errors and weird abbreviations used making questions/answers hard to understand at times; matching, quiz, memory modes seem too easy - answers can be deduced from process of elimination and not a reflection of knowledge of content; content seems disorganized - e.g. racial/cultural identity development information placed under ethics/legal section. Pro: much cheaper than other apps but you get what you pay.
