Yes that questions did require 3sf I remember

It was 28/29/30 Si
28=91.6 29=5.6%. 30=2.8%
(28x91.6)+(29x5.6)+(30x2.8)
Divide by 100
=28.112
3sf=28.1% that's what I wrote
That's what I had, some people had like 21% and I was confused because I thought it had to be 28-30 and considering 28 had the biggest percentage it had to be closer to that

No, 28 is right my bad😂. I though it was 21, because of all the 1s after the decimal point

Yeh most people in our school had similiar answer to mine. But this exam was the hardest I've done in my life so I'm hoping for grade boundaries to be low, which is likely because it's a new spec
4. Can somebody upload the paper? Just so I can reassure myself that I didn't totally mess up.
5. The fact that we have the same amount of time as the legacy papers, despite our exam being considerably more demanding, meant that many could not complete the paper. Perhaps if the exam was given more allocated time, students would be able to actually read the questions thoroughly in order to gain an understanding of the concept being tested.
6. Where do you get the grade boundaries for past papers?

Don't jump to rash conclusions yet. Everyone after both exams found them very difficult. Even on TSR, people found these tough. CH2 last year was 66% for an A, which is low, but that paper was easier than our CH1 paper , so I suspect ours could be in low 60s/ high 50s.

BY1 in 2010 required 59% for an A, 59! I don't think we're screwed, yet.

Good to see you on this thread too haha
Yeah how did you do in chemistry? We may as well have selected math for an A level

Just scroll to GCE JUNE, and find BY1 and you can see the grade boundaries over the years.

Look at:

This also says how many marks you get for each 'real' mark out of 80. In last years old CH1 you could lose 10 marks and still be awarded full 120 marks UMS!

In our lessons there was an emphasis on the fact there would be a LOT more maths. Apparently it says in the specification that there would be at least 25%(I think) maths marks.
11. Thank you! was our test out of 80?

Thank you! was our test out of 80? I think they made it more marks this year. I think it was 60 last year
Last year and this year both out of 80. If you did some really old papers they were out of 66 - I did one for practice and wish I'd done more as they seemed more similar to the new ones.

All BY1 papers listed on there are out of 70.
Ours was out of 80

Thank youu, did you do biology and if you did how did you find it?

Yes I did do biology, and I thought it was pretty hard. I think I scored around 50 marks out of 80.
17. Has anybody done an unofficial mark scheme for the chem paper? I really want to have an idea of how i did

That's really good for that paper, I panicked because I thought it was asking unit 2 stuff so I have no idea what ill get

I'm still gonna resit anyway. I think I lost motivation towards the end of the paper, so I left out detail and answered the questions lazily. Poor Y11s have no idea what's coming their way
