Mock exam paper A Higher Level Marking Scheme

PRE-LEAVING CERTIFICATE, 2011

MARKING SCHEME

HOME ECONOMICS –

SCIENTIFIC AND SOCIAL

HIGHER LEVEL

In developing the marking schemes the following should be noted:

  • In many cases only key phrases are given which contain information and ideas that must appear in the candidate’s answer in order to merit the assigned marks
  • The descriptions, methods and definitions in the scheme are not exhaustive and alternative valid answers are acceptable
  • The detail required in any answer is determined by the context and the manner in which the question is asked, and by the number of marks assigned to the answer in the examination paper.

Requirements and mark allocations may, therefore, vary from year to year.

  • Words, expressions or phrases must be correctly used in context and not contradicted, and where there is evidence of incorrect use or contradiction, the marks may not be awarded.
