Revision Techniques
• Why should you revise?
• ‘cos you cannot remember all the Chemistry that you
have studied unless you revise.
• Where should you revise?
• A quiet room
• How should you revise?
• Plan your break before the start of your revision.
•  more efficient and feel less tired
• How often should you revise?
• Remember: the most important point
about revision is that it must occur often
and be repeated at the right intervals.
• No pain!!!
No gain!!!!!!!!!!!!!!!!!!!!!

Chemistry-Paper 2 (Electives)
• One question is set for each of the
three electives, candidates are required
to answer any
2 out of them.
Chemistry-Paper 2 (Electives)
• Industrial Chemistry
• Materials Chemistry
• Analytical Chemistry
Standards Referenced Reporting

•
•
The standards are held constant
The percentage of students awarded a
given level may vary from year to year
The standards are more informative
Level descriptors together with exemplars
can better reflect the standards
Standards setting
• Based on examination results, candidates
are awarded with a total score
• To determine the minimum scores (also
known as cut scores) a candidate must
obtain for meeting various standards
