Yup I am retaking , took this exam back in jan 2011. I really hope a lot of heart stuff comes up and transpiration seems good too. Just hope it is not going to be too hard "/ .
Yee plant stuff seems very simple and straight forward... heart stufff not to keeen on =\
reliability - repeat experiment 3 times at least, identify and remove anomalous data values, calculate an average (the mean). yep correct!
accuracy - ensure variables are kept constant... ?
use more intermediate values, narrow the range,
precision - more accurate equipment - small increments on equipment...? What are the answers??
hey i was only asking it as a question... but the reliability points were correct .. and accuracy points- more what i wrote... and precision.. what you wrote was the only thnig i can think of =)

Might be a bit late , but what I have found really helpful is looking at the mark schemes to past papers (on the ocr website) and trying to get used to the terminology they use - they can get a bit pedantic!
I've gone over everything again for this exam and done a few past papers. I hope I can do better than my D in January I just hope spirometers don't come up because no matter how hard I try I can never remember how it works hehe.

Agree! And it's not too late. OCR is very specific in the mark scheme.
Ohh the joy of having to do this paper after it was more than a year I was taught the content!
