Think you can read better than a 6th grader? Find out by reading these books. As far as I've seen, these books are all the pinnacle of reading and writing. Utterly follow-able, absolutely written by subject matter experts, and written to make sure you can read at an "analytical" instead of merely an "elementary" level. If you're better than your average high school reader, no worries, these strategies will take you to a "syntopical" level. Find out what kind of reader and writer you actually are. Buy these books!
P.S. If there is a more expensive version of a book, that's because it has more material or is a hardback. If you have questions, read the description and/or message me and I'll guide you through.
