    thanks leukocyteng

    My Jamb mock centre is Knowledge Partners Limited in Uyo, Akwa Ibom State. I arrived at the Examination Center around 6:30 am, as the exam was supposed to start around 7 am, but we were still delayed till around 9 am. We were asked to drop or Pencil outside at the clearance gate as we were not allowed to go into the exam hall with any material, apart from the Exam printout, We were all confused as some of us writing calculation subject was asking the supervisor what we are going to use to do some rough work in the exam hall, but it all turns to a deaf ear as he was focused on his words.
    Getting into the exam hall we were been shared Jamb rough sheet to do all our rough work without any pen or pencil, this was another height of frustration as we complained but it all turned to a deaf ear.
    We had to do all our rough work in our brain, imagining calculating Physics and Mathematics in your brain, that's what we experience at our centre.
    The Center was okay, despite the harsh weather there was no Network or Power failure as the exam went on smoothly. The Cbt Platform was ok as expected and I noticed a pop-up window when I delayed for about 3 minutes without answering any question, the Pop-up windows informed me that I'm yet to answer any question and I should call an administrator if I'm experiencing any problem.
    Total questions given was 180 and the CCTV cameras were working very fine and it stationed at all nook and crooks of the exam hall.
    Lastly, one question in English caught my attention I was asked to state the course the Author of the Literature "THE LIFE CHANGER" Studied in University. Honestly, I just choose English Education as I did not bother to read about the Author biography while studying at home. In physics, there were some blank questions without only answers provide, while some questions were given but all the A, B, C, D answers were blank, Jamb should fix this error before the main exam.
