Edexcel igcse biology may 2012 exam discussion

For the crisp question, I only mentioned burning it and weighing the initial mass then the final mass and working out the difference. Then I just said work out calories from there. Will I get any marks? :frown:

I did the same thing as you. I think the marks are for the describing the experiment. I don't think you need the formula but it might give you an extra mark if your answer isn't clear cut but if it is i think it should get 4/4 :wink:

I'm afraid you don't measure the change in mass of the crisp you measure the change in temperature of the water so unless you describes the correct experiment I don't think you'll get many marks :/

I was expecting an AA (double award) for my science. However, I got an AB in the end. I'm not sure how they deliever your results in Britain but in Asia they only give you the grade you got not the marks for bio, chem or phy. To be honest, I did really bad for my biology like I didn't do the last 6 marks question. I'm pretty sure my physics carried really hard to get an AB. Now that IB started I'm considering to drop my Biology standard for something like chemistry. That would leave me with a higher physics and a standard chem which is really good to get in to universities if I get good for them. Do you know a way to know how well I did for biology without paying to review the exam paper. So that I can pick which subject is my strength
