Passed the VCP-DCV 5.5 exam! The whole study process took about 2 month of studying 1-6 hours a day. I've maybe had 3-5 drinks in 2 months...

Lots of caffeine, nootropics, water, soberness...I've became a pill popper in the last 1-2 months.

5 hour energy -extra strength before exam to be extra alert. Time

Took the stanly.cc course...Great value for the price!
Used Scott Lowe's Mastering vSphere 5.5 book & CBT Nuggets.
Enrolled in the VMware VCA-DCV free online course and quizzes.
Used VMware workstation.
Built my own ESXI 5.5 server on a SSD HD - Lenovo TS140. 40 watts/hour, quiet and powerful.
Helpful things? Having previous experience with VMware Workstation and ESXI experience. Having hardware experience (A+). Having Network+ or higher knowledge. Having storage knowledge. Do all of the labs. If you don't understand it, do it over again. VMware's new VCA-DCV will actually teach you a few things. I recommend it to establish base knowledge. Read the blueprint for the exam!
