To kill a 'mocking-paper'

the alarm in hall is annoying
esp. during recess period(10:30, 10:45, 10:50) & roll-call period in the afternoon(1:50, 1:55, 2:00)
can someone pls demolish it?

insufficient time is the major weakness
it's useful to know how you can manage your time on your revision
and on the Qs during the exam

during the exam,
kenneth's method - get your ans. by wild guessing
or kc's method - randomly choose a MCQ ans.
