Do you know the meaning of 'a crash course'? I want to know the meaning of 'a crash course'. I read a book and came across the word, which is hard for me to understand. The sentence is this : "So this book includes a crash course in a new science of stress and what psychologists call mindsets." Q. What is the meaning of 'a crash course'? and could you show me some examples of 'a crash course'? To help your understanding I abstract other sentences from the book. The advice in this book isn't based on one shocking study-even though that's what inspired me to rethink stress. The strategies you'll learn are based on hundreds of studies and the insights of dozens of scientists I've spoken with. Skipping the science and getting straight to the advice doesn't work. Knowing what's behind every strategy helps them stick. "So this book includes a crash course in the new science of stress and what psychologists call mindsets".
