“When it comes to [performance-base] evaluation, book smarts just aren’t going to do it for you, because things don’t work exactly like you expect,” Shawn Powers, an online trainer for CBT Nuggets and editor for the Linux Journal, told Linux.com for our recent article on how to study for a certification exam.
