So after a marathon of three months full of studying and labbing I passed the third and final exam of the MCSA track, namely 70-412. All of these exams are pretty tough, but I believe 412 is the toughest one of the lot, thankfully many of my questions revolved around AD DS, DNS and DHCP, which happen to be my strong points.
Like I said, I've been studying for three months, and especially the past eight weeks have been full of studying and labbing. I must have used 10 hours each weekend on studies the past eight weeks, so I definitely feel the certification is well deserved. Obiovusly there are a few areas I can brush up on.
What has been particularily difficult while studying for 70-412 is to try to learn AD RMS and AD FS, while simultaneously try to learn something entirely else (Citrix Xen7.x) for work related purposes. Cramming in that much information into ones head is certainly not something I'd recommend. 

I used the official training guide, exam ref, Matering Server 2012 R2 and technet (to fill in the gaps) for all three exams. The exam ref books give some good hints, that you might not think of otherwise.
Plan forward is to go for the remaning two (413 and 414), to achieve MCSE, but first I'm going to take a well deserved (short) vacation.
