  multiplication / division before addition /
  subtraction

• Weak in simplifying negative fraction

Section B Q. 4

• A significant portion failed to set up the
  correct equation
• Some even misunderstood that the two numbers are
  consecutive numbers
• Some failed to define the unknown properly, which
  leads to the deduction of marks regarding poor
  presentation
• Some others clearly defined the unknown but
  failed to draw a conclusion after solving the
  equation

Section B Q. 6

• (c) (i)
• A worrying proportion used equality sign to set
  up the algebraic expression instead of an
  inequality as required

18
Section B Q. 6

• (c) (ii)
• Performed poorly in proving whether a certain
  number satisfies the inequality.
• A significant portion just presented with a
  bunch of numbers without any statement and then a
  conclusion was drawn

General Recommendations

• Seventeen candidates have more than 5 marks being
  deducted for poor presentation and the wrong use
  of units. One of them have even committed in nine
  of such mistakes. You must take note of the
  importance of proper presentation.

General Recommendations

• Another important issue on presentation is the
  proper use of statements in your workings. Many
  students presented their solutions with simply a
  bunch of numbers and then using the final number
  to write a conclusion. This poor habit in
  presentation must be improved as you will deal
  with more complicated manipulation and logical
  arguments.
