Qbb 3053 - Practical Lab Test

Dear Students,This test is dedicated for Practical Lab Test. I will open this link from 9 PM to 1 AM, Thursday, 18th August 2016Please fill in your correct name & ID based on the pdf file given to me for your group members. "PLEASE DO NOT CHEAT by entering fake ID. Failed to do so, I will deduct 20 marks across the board" Good luck for your test. Luluan Almanna Lubis
