Sorry buddy!! You won't find one. I went through the same question two years back and to my disappointment didn't find the paper. The university doesn't provide sample papers on their website (don't know why).

Don't stress about it. Paper is quite easy and no negative marking is like a cherry on the cake. And also there's no chemistry so that is a bonus for some students.

Feel free to ask more stuff

I hope this helps
