dafuq you were in year 10 this whole time? Thought you were in our year
You are by far the sickest year 10
Other than that I think that you should familiarise yourself with the content rather than going through past papers straight away. The best way to do so is by working your way through the preliminary textbook, if you can get one during the holidays.
This is a link to the 2 unit cambridge year 11 textbook. I gave you this because for the first few topics in year 11 they are most likely going to teach you 2 unit topics like absolute values, algebra, etc. which will have very few three unit components, then you will eventually move onto purely three unit topics like parametrics and circle geometry. This all depends on your school though, because different schools have different topic orders.
Good luck and I'm glad to see a year 10 student taking initiative in going ahead, but do keep in mind that you MUST have a rest these holidays.
After you're confident with the theory and how to apply it to questions then go onto the resources section of this website and then do some past papers from the preliminary section.
All the best with your studies
EDIT: I don't want another infraction for a bs reason
Here's a link to past papers though:
