    I don't think it was Spearman's.

    I'm almost positive that it was the T-Test as it was comparing two means.
    If you write outside the lines but not outside the margin will it be marked??

    I accidentally forgot to add an extra zero for my magnification! I only just realised that as soon as I closed my booklet! Rofl!

    The calibration curve was a mess for me

    Other than that it was all good I reckon. Seems like a pretty standard paper for me other than a couple of marks.

    The examiners will be able to tell that you wrote outside of the lines and will be able to flag it on their system for review. Don't worry about it.

    What was the question on cancer?

    Something something HPV

    How does a vaccine cause antibodies to be produced? 4 marks

    Then there was the graph with antibody concentration against time with 2 and 3 shots of the vaccine. Which was better + why - 2 marks

    T-Test is when you compare two means to see the difference between them.

    I just put vaccine has dead pathogens-isolated antigens so stimulates t cells and b cells and b cells produce plasma cells which secrete antibodies
    And i put 2
    But not sure if any are right😂

    I don't remember the options at all! Sorry!

    The only option I remember is the RNA which I didn't tick and I know that's wrong

    I got close to 10, 9.something

    Did you draw a tangent at 10 minutes and calculated the gradient?

    How many marks is this?

    As the cells grows more and more sucrose is hydrolysed to produce glucose and fructose for respiration to produce atp and energy for metabolic reactions.
