    Resigned to the fact that I'm going to fail biology. I have English lit tomorrow morning and I only get a 2 hour break... Plus I keep making silly mistakes which are costing me like 3 grades per paper
    Same here but I have quite a large break between exams - my morning exam is only an hour (until 10:30) and the next one starts 2pm.

    You're gonna do fine. Just focus and make the most of your few hours this evening and then get some nice sleep. The exam is at 13:20 so you will have a good few hours in the school day to do some questions.

    Does anybody have any predictions for tomorrow?
    Also is the first paper more practical based and the second more knowledge based?

    There will be no long answer questions on the first paper and instead there will be data analysis/comprehension questions at the end.

    Good question - We've always been told to draw dot-to-dot for biology. For one of our mocks there was a graph which had a blatant curve to it but we had to join it dot to dot. I had no idea why.

    If anyone can clarify this too I would be most grateful.

    Hi!

    Dot to dots are use for when the intermediate between valvues isn't known...

    for example for a pH and enzyme value, you would have to use dot to dot because you don't know whether the values would actually follow the pattern in between your data.

    However for something like total gas produced you can use a curve because you wont go from suddly 100cm3 to 50cm3 back to 200cm3 because once you have produced gas you can take it back...

    really bad explanation but i hope this helps !

    No idea about Spearmans (Unless that is another name for the correlation coeffcient test?)

    Use Chi-Squared when comparing CATEGORIC DATA and if you want to see the DIFFERENCE between the OBSERVED and the EXPECTED results

    T-Test when comparing the MEANS between TWO sets of data.

    Do we need to know the formulas off by heart?

    Spearman's is another correlation test. You only need to know one or the other.

    All formulas are given. Even the index of biodiversity is given.

    At AS Level you are not required to calculate the statistical tests. You only need to be able to analyse the data given and come up with a null hypothesis for example
