CIP points is counted as part of your CCA points. Say you clock
60 hours of CIP and you get a minimum number of points (eg 6
points) added into your CCA tabulation score. If you get between
25-30 or above 30 CCA points, 2 points are deducted from your O
level result.
And no, there are no other channels for you to get any deduction
besides special language pragramme, HMT and CCA.
