It wasn't hard thats a fact. I wouldn't say it was too easy as well. If you didn't revise, you probably didn't do well because that test needed revision. Chemistry on Thursday, it is looking hard.

it was pretty easy! lets not jinx it so ill say its a good paper! but I guess the grade boundary will be low because many people in my grade were not confident with the paper some even left questions.

Yeah it was pretty easy, but since everyone's saying that, the grade boundaries are probably going to be pretty high. Either that or paper 2 will be super difficult :s-smilie:

To confirm, a lot of people have mentioned a question about a punnet square concerning blood type? Are you guys talking about the AQA exam just in the wrong thread or did I miss something?

Triple had a 6 marker about punnet squares.

I thought it was really easy but I ****ed up both 6 markers so lost at least 8 there. Plus say another 10-15. I should hopefully get an 8 still. Ran out of time to check as well

What did you guys put for the lens one?

I put the diverging lens (can't remember what letter it was) because it refracted the light rays out so the lens could make them meet at the fovea (or something along those lines)

I said it takes from receptor cells in the skin to the cns (Hopefully at least 1 mark :biggrin:

)

also question 1 was solution y, and benedicts solution where when added it turns green if less reducing sugars and red for high amount of reducing sugars. um the tentanus one was weaked form of pathogen is inserted into child and (immune system) white blood cells respond by the lymphocytes prodcung specific antibody which attaches to antigen where lymphocytes divide many times to produce many antibodies which destroy the pathogen also memory lymphocytes remain in body in case if the pathogen enters again it can produce specific antibody immediately and kill the pathogen.
