Take a complicated topic - use nice, simple language - throw in plenty of diagrams and tables - AND you've got Crash Course Pharmacology. Amazingly this book is not going to weigh you down and still managed to retain a good core of knowledge that the PBL student needs to know. They've even managed to fit in MCQs and EMQs to test what you've learnt. A consistent format throughout the book makes it easy to read and learn from. Just what you need for PBL pharmacology.
