Plzzzzzz help!! Cl C CBSE projects!. My teacher gave me last year's topic, I started working on this year's

As you might be knowing, all cl IX AND X students are required to make 2 project during the academic session. As the new list of projects was released late, my teacher told us the old ones - land and water based disasters, and asked us to choose any1 of them. However, I was absent on that day, and didn't know. But l8r, I started working on one of the projects given in the list on the cbse.nic.in: Pocket Guide on First Aid! What do I do now???? Should I finish it, or start all over again? The new list doesn't even have those projects!!!
