Welcome to Savvy!
The structure of the workshops should work well for you.
Typically the instructor posts lessons on particular days and assigns homework. You can complete the homework and post according to your own schedule, but they may request that the homework be done by a certain time (e.g. within a week).
Sometimes, the instructor will arrange a chat at a certain day or time to discuss a topic or to provide an open forum for discussion. In that case, typically the instructor proposes several dates & times and a decision is made by majority vote. If you can't make the chat, no worries! The moderator will post the transcript.
Please let me know if you need any additional information.
