Raven's Progressive Matrices™ Practice Book: Prepare With 100 RPM/SPM/APM IQ Questions With Explanations (IQ Tests series)

Needs editing. I was captivated by the puzzles but from the blatant error on #73 where a piece is omitted, to the spelling errors on the back cover, to the “solutions” that absolutely do not under any circumstances match the puzzles (e.g. count of points on the side of a line), this can be a frustrating book.The cost of these books is prohibitive: I had to buy from eBay to start a collection. I appreciate how hard it must be to come up with the matrices and would feel more comfortable buying new if I knew that the suggested rules really matched the puzzles. Before cementing my judgement I’m going to try a few more books.

Needs more complex APM 3 problems and solutions, otherwise this still reads more like the childrens version vs the adult.

Good book
