The quarters run from
- July 1 - Sept 30
- Oct 1 - Dec 31
- Jan 1 - Mar 31

When you sign up, you don't have to meet the quotas until the NEXT full quarter. For example, if you sign up August 15, you have fulfill your quota by Dec 31.
Quota amounts are the same for all demo. SU does not distinguish between "full time" and "hobby" demos. In SU's eyes, a demo is a demo.
