There is a serious problem with exams base data imported using SchoolBase versions 3.9.1 to 3.9.13 (Released 4th Feb 2010 to 10th March 2010). We will let you know if your data has been affected, but please do not import exams base data using the version numbers above. If you need to import base data we have now released 3.9.14 which fixes this problem, please make sure your SchoolBase is updated to this or later before importing.
