2 of the most valuable classes I took in College, weren't even College credit but continuing ed. credit.
Reading, Listening and Study Skills, had a speed reading section, where we used machines to help train, a note taking section, that taught a rules based but streamlined, outline organizational style that was super efficient and I'd never seen before (very helpful to me) and a very logical method to read text books, based on basic psychology of how memory works and structure rules of how things are written. The time saved, was off the charts.
The next was Pre Employment Preparation. Demand, supply and compensation studies, of various careers (helped me switch from Architecture to Eng.), resume writing and filmed, peer critiqued, mock interviews.
They were both, so helpful, I could make the case that they ought to be required.
