I only had to BS a few multipul choice and did n't know one short answer question for sure and at the end of the test I seriously felt lighter and free , seeing as the final road block had been demolished and NDK was in sight after it 's takedown . Also , we talked about the " Hard on " ... Hadron Collider thing and how it was apparently supposed to create a replica of the big bang or something and how it would kill us all and apparently it was turned on today , or so I hear . Yup , quick search on google it was ... and I believe that 's a cute little cartoon version of it below the google logo if I ' m not mistaken .
