Hey,
In order for me to give proper advice about how you should prepare for your SAC, I think I need to understand, why are you at risk of failing next week? Is there anything you're specifically struggling on, or are you feeling lost with the entire course so far?
If you're looking for general advice and nothing specific, then I'd suggest reading these articles
Nevertheless, remember if you need help with a specific methods question you can receive it here. Post your question and I'm sure someone will be happy to help.
