I think examination is a true test of knowledge for now.where doubt comes in is the issue of MALPRACTICES.Though exams performance can be affected by conditions like illness,state of mind,exams fever and rest!but a candidate should find answers to some of those conditions.it happens to me when i'm in sec school ,i always fall sick a day to the exam period and get well as soon as the exams is over .until i find answers to it MYSELF.even if another method is invented those 9ja bastards won't manipulate it.nigerians think!
