Hi,
The complete picture of the new immigration system to be open from May 4th, 2013 is not yet out. There are still areas like the eligible NOCs, cap on each NOC, credential assessment partners, etc which are not officially published. However, based on the information provided by CIC so far, some immigration consultant had prepared a points chart which can be temporarily used as a reference in calculating your points. You can calculate your points easily usng the help of this chart, which is self-explanatory. As far as I can see, the CIC website has not yet started displaying this point structure. Remember, CIC has the final say! Here is the link below:

Hope it helps.
