RIP
But its fine as long as you do good overall on the test and i think you still get method marks if you make a method

Yes I think so, as long as the experiment could viably be carried out I can still get half marks at least :smile:

Yep just be confident
THE CF question was dead easy tbh
It was good and bad at the same time am actually not gonna liend. I think I didn't really do justice to the 6 mark questions. Plus the fact that most of the things I revised for didn't really come out. There were just lots of investigations and tables to derive answers from, which are not really my favourite things to do. I feel bad cause I absolutely love biology but I don't think I did as well as I wanted to do.

you can use iodine indicator which will turn black if starch is present and starch is a carbohydrate

You might have had to put both because it said different types of carbohydrates

Yea i'm kinda confident with that one
Using benedict solution will not help ur investigation because this indicator detects sugars which are not carbohydrates they broken down carbohydrates so the indicator will not change colour to brick red and will not help u detect carbohydrates so u had to use burette to detect protein which will turn blue to purple if it is present and to use iodine solution like I've said

All of the people that took the AQA paper found it hard so have faith in the low grade boundaries.
