1. Take a book you need to study and read the first paragraph under the heading of each Chapter and Sub-chapter (and sub-sub-chapter if it's a difficult subject) aloud into a recording device. 2. Play back the recording to yourself while you work on the Tesla unit. 3. Find a quiet place and read the book all the way through, including the parts you'd left out, then take a good nap.
Do that, and you will pass any test based on that book, without notes; I guarantee it. Playing subject appropriate instrumental music softly in the background while you read and listen to your book helps, too; it's a mental lubricant. Advertisers know that well, of course.
