It is a great idea.
However, these are timed tests and are not really designed to be studied by subject or in printed manner similar to all other GMAT Cat tests (GMAT prep, Kaplan,
Manhattan GMAT, etc) - rather to be taken online. You may want to get a
MGMAT guide or PR 1012 that are organized more like question collections rather than tests.
Another option for you would be to get them as an App on Apple iPhone/iPod - there is a beta with 37 questions if you are interested but it will be at least a few weeks until the final version is out.
