Ziggy has become the first Big Brother housemate to earn guru status, making him immune from this weeks eviction.

Big Brother set the housemates a general knowledge quiz, and they scored a dismal 38 out of 90. BB then gave them a second chance and the housemates improved their score to 48 out of 90. Although the housemates, collectively, improved their minds by 26%, Ziggy made the biggest improvement. Big Brother announced:

“The housemate with the greatest mind improvement - a whopping 200% - is Ziggy.”

Two more tests to go……who will join Ziggy?
