There are 3 tests in that cert. The TSQL was pretty straight-forward although there were things I wasn't that familiar with coming from MySQL. The server was my weakest part and it's probably the most meaningless for a SQL/BI guy. The third was for SSIS and database design and it was, easily the broadest, and hardest to me. Although, ironically, it was also my highest score.
But, that's for 2012, and doesn't apply for 2016 apparently.
It looks like they've, again, changed it for 2016 and there are 3 tracks. Unfortunately, for someone like me in the BI space, I'd need two of those to really do it right as a learning experience.
I hate to give advice on it but I don't think I'd do the 2016 track. Unless you've got time in that niche, it took me a month, sometimes a couple, of pretty heavy study to pass one of the tests. So figure 3 months for both if you can commit a lot of time to study. I guess that might fit your time-frame but it also might be longer if you start from zero. Also, if Transcender is still around they can be useful for getting a feel for the tests but at a cost of another $149.
Whatever you do, good luck with it.
