This is the best general overview of the test, but the chapter on the writing section of the test is still frustratingly inaccurate, as is the writing section of practice test one. I don't understand how ETS could leave this inaccurate content in for yet another edition of the book.
Note, also, that this is the most recent version of the book, but it does not reflect the changes to the test in 2019. Apparently, future PRINTINGS will include an insert that describe them, but ETS has no plans to issue a new edition anytime soon.
