BRS ones are not very good.
They just ask 1 question, which is usually not very hard, and give semi- complete answer on the other.
Lange Cards for path and micro are much beter
Pharm cards are good too.
All I used the BRS Path cards for was for quick review the day before the exam, just as a refresher. I wish I had used Pharm cards a lot more. They're just chock-full-o'-good info.
