1. Before you start, please download the csv file from CIMA site. It tells in detail which fields you need practical experience. Try your best to list your working expeience to cover the required.
But if you are lack of experience on one or two fields, don't worry, you can emphasis your experience on other fields.
2. The CV should be in details.
List when you achived in last couple of years, list all daily works you do, projects you were involved.
Then pick up three or four cases. What the project is, when you did in the project, what issue you come across, what method you used to resolve the issue, at the end...what the overall results of the project.
