[Paranauts]

So if i wrote gametes/genotypes/ genotypes in the punnet square correct... Will i get 4/6?

Yup, I think you will.

Man wtf was that paper. I cried after coming back home, literally. Even the questions that I knew, I ended messing them up. Sigh, so demotivated and disheartened. I have a 102 in AS and was really hoping for an A*, worked hard the entire year but I don't think it will happen..

same situation here mann 103 for AS, doesn't seem like happening in A2, the paper was different and lengthy :/ that genetic diagram question of BRCA thing, i dont think anyone in the whole school did it here what'd yall write

Guys please be honest. Looking at the difficulty of this year's papers can i hope for an A if i expect a 170-179/260 total?

 

[anwar786]

anyone know what the second long question was even on?

 

[darks]

The poll can asure you that it was a large number that found the paper hard. Hopefully gt will be in 50s. I mean 2014,2013 M/J papers were not this hard and had a gt of 56/100. Lets hope for the best.

what


what percentage did you get for AS?
I got 88 but don't know the actual mark I got.

How do you know the percentage? Don't they not give it out anymore?

 

[Syed Umar]

Second question part a was about nervous and hormonal coordination.
Part b was chemoreceptors.

i got 90 but like the actual mark they gave it out some time later last year

 

[darks]

Guys please someone answer this. Is 170-179 ok for an A out of 260?? Considering this paper's difficulty? I am so scared rn.

considering last year the a* was 179 with an easier paper, you should be good

 

[Qib666]

Guys, were the first 2 answers pyruvate and CO2? I'm not even sure...

that's what i wrote too

 

[AnonymousX9]

What about the 5 marks waste products question? Can we write about CO2 in it?

Lactic acid.
Edit: CO2 is wrong as it is only a product of anaerobic respiration in yeast. Here only runners were considered
