All the GRE: Effective Strategies & Practice from 99th Percentile Instructors 6th Edition

Been amazing at helping me in my journey!

For those who know anything about textbooks. This one has a very common issue. The examples given are perfectly simple while the practice problems differ from the examples given so much that reading and re-reading instructions will not help.This becomes incredibly clear during the sections on factoring (the reverse of FOIL). In the quadratic equations section. Sure, it's alot of info in one book. However, the laziness of the examples and practice problems shows.It proves an old adage that, someone could be the smartest person in the world, however, they would make a horrible teacher, because they can't understand what others need to know of the subject matter.
