I'm doing the same task, but I've chosen Eid. We've just finished our technical exam in early December and basically it's to show complex skills to the examiner. You can't do the same dishes that you are planning to do for your final, but you can make them similar. I used skills such as tenderising and marinating, deboning a lamb shank, making bread, making pastry (all from scratch), etc, and my teacher gave me a 9 / A*. So for yours, if you plan on doing the cheesecake and laddoo, you need to make sure your other two dishes have more complicated skills. Otherwise, you won't be able to reach the highest grade boundary. Hope this helps.
