Paper 1 barely had any probability/stat question, so I knew there was going to be a lot in paper 2.

I tried to manage time well after not answering almost 25 marks in paper 1, but I still didn't have enough time, and I didn't answer to almost 30 marks I think.

I could've made more use of calculator to save some time, but oh well it's over now :P

Found it way easier than paper 1. Although i've never really know wth is up with the systems of equations... was a = 4 or 5? memory blurry now but one of those two right? I just eliminated variables...

In paper 1 i didn't answer like 12 marks but i just know that some (like the last question) went terrible. In this paper i answered it all :P

Thing is this paper had unnatural questions to me but i managed to work them out. section B was a surprise! the prob. distribution function question y think i got the final answer 0.014 s.d. smthing like that.
