MGMAT Book (+6 free tests) or 1 year access to MGMAT tests?

I was in a similar situation was deciding between buying a book ($29) and getting access to the 6 tests or getting the 1 year access. What made the situation different for me was that I already had picked up the 8 strategy guides on craigslist, so I would have an extra book if I bought it. Furthermore, despite 1 year access, I only had 6 weeks until test date, so I wasn't sure which to choose.

I ended up going with the 1 year of access since they had a sale a couple of days ago and got it for ~$70. I think that's the way to go, because what's arguably better than the tests themselves is access to question banks. For example, I took a CAT and found that I did poorly on geometry. Well, the geometry test bank had a complete quant section dedicated entirely to geometry. That's 37 questions of geometry, and needless to say it helped a lot. The challenge question bank will also be helpful, since if you're going for a 750+ score, those questions are pretty rare.

So, if you can afford it, definitely go with the 1 year access. I'm going to allow my friend access to it after my test date, since it still will have nearly 11 months of access left.
