My strong advice is to get a coach. They are essentially time levers…if you have a week, time is not on your side.
In addition to that, figure out what material is the most direct path to ramping up quickly. Focus only on what matters (don't try to boil the ocean).
The moment you feel somewhat comfortable, get casing. Practice as much as you can, but make sure you have time to reflect/learn from each of your cases (I don't advise doing more than 2 cases a day).
I have a 35 page Capital One case collection for your reference. I'd be happy to take you through it!
