They change every year plus there is a new spec so nobody knows.
i wanted to kno the grade boundaries so i would kno what mark would get what, and even if they change, a previous grade boundary can be similar to the next years gb.
My teacher predicted my Biology one, based on the grade boundaries for the core GCSE ISA certified last year. I got 36/50 which was an A grade (83UMS) in that ISA, and is also her prediction.
I was told I got 38/50 in one of my isa's and my teacher said that would be roughly a C?
Are you doing single sciences? That's a much lower grade prediction than my school have predicted, and the predictions made by other schools that I know of. I got 36/50 which is predicted to be an A (83UMS).
Im doing triple science, but all our ISAs are based on b2 c2 p2 if that means anything to you. I don't know if thats core science or additional or whatever. If you mean single sciences a grade in chemistry physics and biology seperately rather than core additional and further science then yea
Oh well done! Can you help me on the method? Do we basically heat water by burning the fuels methanol ethanol butanol and propanol? And, when we burn them do we have to separate tables? One for mass change and one for temperature change? If not, what is the table meant to look like?

Dont worry 38/60 is higher than a C! High B or possibly an A ,

Ahh we did it so long ago now, I think the table was the type of Alcohol, then mass of alcohol before and after. Temperature of water before and after as well. Then you work out the specific heat capacity or something?

Oh crap, i thought we were meant to have two separate tables so we could include repeats-.-

And oh i think you were meant to work out the energy produced using the specific heat capacity of the water?

Yeah thats the one you had to work that out then see if it supported your hypothesis.
What I did for my most recent Isa was try and write my answers in the exact same ways as the 45/50 mark exemplar paper, and just expand where he lost marks. If it isn't on the exemplar just answer them the same way. www.sciencelab.org.uk/support/exemplars.php

Just include repeats on the same table, and when you draw the graph if you have anomalies just move them up on to the line, then change your data in the table hahaha, saves you having to write about why you had an anomaly in the exam
