i'm a multi-year test taker, so take it with a grain of salt, but my take is that gips is kind of a freebie. in years past, it hasn't been that difficult - very high level stuff to nail 10% of the exam.
they might give you a snapshot of their returns, some language at the bottom, and maybe a vigenette to go with it. you'll have to pick up what is wrong with the returns, the disclosures, and story.
that's what i'm hoping for ... now if they ask some real estate question, i'm like a turtle on it's back.
I haven't touched schweser since 2002, so no advice here. the eoc stuff out of the books is NOT bad, and some of them are previous years exam questions.
