Makeup exam (added Nov. 20)

The exams are conducted twice and the higher score will be adopted. Therefore it is OK to be absent from one of exams, but you can claim a makeup exam if you have unavoidable reasons.

  • Acceptable reasons are same as the final examination. (See SFC-GUIDE Vol.2 p.34)
  • You can take only one makeup exam even if you are absent from both exams.
  • The makeup exam will be conducted in the last week. Please ask your teacher for detail.
