I just passed 70-680 – Windows 7, Configuring.
I got a free exam voucher from a local training facility and just went to take the exam. Unfortunately, all server exams were already booked, so I took a client one – not that I have anything to do with client OSes in my work. I got 100% on all the “server-like” functionalities (backups, permissions, security, network configuration) and a bit lower scores on the other – but the results is – another exam passed, for free this time.
Long live free vouchers!
