Unfurtunately I think the Grade boundaries will be high this year. All my peers, my teacher and most people on here say that they found the exam easy (I found it easy, but I'm sure I made some silly mistakes). However, I go to a decent school, and TSR members are usually quite bright so I can't be sure.
Don't compare yourself to anyone on here

Aiming for 108-112/120.

I didn't get the answers to the questions concerning cracking - that's all I know I definitely got wrong.

Other questions were a little hard, unsure about a few. On the whole, it was an average paper in comparison to the others.
i feel as if i did well on the cracking section, just not the other sulphate crystallisation question idk

most schools that are doing the paper are decent schools unfortunately
the paper was easy an we still have a chance to gain another 60 marks so its all good, electrolysis will come up on the next paper btw

I do Double Award Science meaning I don't have to do another paper, my chemistry IGCSE grade is based on this.

I know 10-15 marks I definitely got wrong and then there's quite a few I'm a bit 50/50 over.

How do you or anyone think the grade boundaries will be? Apparently it was around mid-60's for an A last year.

My overall science grade is out of 360 as they take our results from Chem/Physics and Bio and get an average.

I'm soooo scared! I know I got 5 marks wrong and then other stuff I was slightly unsure of! Got a C in mocks but I've done a maassss of revision since then and got 104/120 in the 2011 summer 1C which was really good for me because Chemistry is my worst subject by a long way! But I'm scared that I haven't done as well as that in the practice as I am really hoping for an A*!! Does anyone know the answer to the question about what the specific polymer was used for by the way?? Thanks!! Xx

I think it was Poly (Propene) and used in plastic bags I put

I too am worried, and I'm praying for 70% or above which would hopefully get me an A?!

That's it for me and Chemistry, I'm in Double Award so I have no extra paper.

Maths and Spanish tomorrow.

I was a little unsure about that one as well. Why was the sulfuric acid heated prior to adding the Copper Oxide? And why was the solution filtered in step 3?
I think it was heated to give the particles more kinteic energy/increase collisions to increase the rate of reaction. The mixture was filtered to remove excess copper oxide.

was the metal the one with high boiling pnt and only conducts electricity when liquid (not solid)? and the polymer we had to name was it poly(propene)?

No, the high boiling point one was diamond I believe (correct me if I'm wrong). The metal was the one that conducted electricity both in liquid and solid form. Yes, poly(propene) is correct

Poly(propene) is not used in plastic bags. It is used in ropes and plastic crates.
Poly(ethene) is used in plastic bags.

oh well about the metal one, at least the polymer one should be right, aiming for a B so hopefully I can get it think I got isomer one wrong too :/ jusg going to have to wait for results now!

It asked you to draw an isomer of pentane or butane, I can't remember.
