It was alright, just quote data, calculated gradients, describe correlations, and then state the role of the myelin sheath and how this impacted on the conduction speed.

I personally think I did quite well on the last 6 marker but it was hard, I've never seen anything like it before! I spoke about the role of the myelin sheath, what the graphs show, what this shows about the myelin sheath

yeah also the diameter for the first graph was 1,2,3,4 but second one was 100, 200,300,400 if you guys realised that

I predicted that drugs would be a big thing and next thing you know it was a six marker!!! All of our teachers got the predictions wrong! Overall it was a pretty good paper. The last 6 marker made me look twice though. Bring on B2 and B3 - oh and the rest of the sciences!

I thought it was an awful paper, i don't know if i'm over thinking but because i go to a grammar school everyone seems to think its a great idea to shout out random stuff just before the exam. I can't seem to think what i got wrong it's just i wasn't very comfortable with the questions..

for the first question, how does cystic fibrosis lead to an increased risk of lung disease
It makes the body produce excess mucus which blocks up air passages in the body (e.g the lungs), guts and pancreas

(That's what I put at least)

I think that the paper was overall pretty easy if I'm honest, does anyone else think there was a lot less content than what you revised for? There were just loads of difference calculations and a couple percentage ones...?

Its the mucus, it sticks to the lungs and makes it difficult to breath, so the bodies mechanism cant prevent bacteria from going into the lungs and the bacteria/pathogens create an infection, For the healthy male, he can prevent bacteria/pathogens from creating infection in the lungs.GUYS TRUST ME, THIS WAS A HARD PAPER AND I WOULD EXPECT THE GRADE BOUNDARIES FOR AN A* TO AT LEAST BE 45. NO ACCURATE ESTIMATION BUT ACCORDING TO THE LAST QUESTION AND THE ONE ABOUT MRSA, THE WORDING WAS QUITE DIFFICULT, SO I WOULD REVISE MORE FOR B2 AS WELL IF I WERE YOU!

wouldn't say there were loads of calculations just two or maybe three

The synapse is the gap between 2 neurons. You've got the pre synaptic knob and the post synaptic knob.The neurotransmitter diffuses across the synapse into the receivers and the electrical impulse continues

I put that but also put the mucus stays in the lung airways/lungs so the bacteria replicate and produce toxins

The question about why is a hybrid hard to classify I put , because they produce infertile offspring, but it should've put fertile offspring 😩. Also the 6 marker on the 4 drugs I stated what they did but also how they carried out the function, e.g increase neurotransmission for stimulants but the question said name 4 different types and the effects on human body so did you to just say stimulant , decreases reaction time , e.g caffeine

For the drugs one. I followed the same structure as you. eg Depressants, EG Alcohol, then it increases reaction time because it takes longer for the neurotransmitter to get to the receiver in the synapse

Damn it, I mentioned ciliated cells! Guess that's -2 for me, then. (Although to be fair, I also mentioned that bacteria cannot be trapped from the air, so they can enter the lungs. I think that might be one mark.)
