A level Biology: Post your doubts here!

[mm89mm]

Paper 21 was really easy. Although there were some tricky questions, such as enzyme's, I mean I never saw a question loke that before, as for the rest I had some trouble about the immunity questions, the 4 and 2 marks questions. I hope in sha Allah I'll have an A, Let's see the threshold. As for the time I took to do the paper I finished it in kinda like 45min, what about you guys?

Guys can you send me some notes or links to study paper 5 notes? anything really i found some but they were very similar to p3 ( as level ) please help thanks

It did not went as per my expectation.....it was kind of tricky...how was yours?

Same here I felt it was super tricky and surprisingly couldn't even complete it in time. Disappointed but oh well. I do know people struggled because my friend who is a GENUIS struggled on it too BUT we shouldn't get down, let's aim for the best and ace the MCQ's etc

How was ur paper? V21 right!

Yes..
It was an easy paper, with some exceptions only; like antibody production, i thought for a while it is an immune reponse but was able to distinguish that immunoglobulines produced by protein synthesis later :/ , (feeling irritated right now)

Yeah, let's show CIE what we are made up of.....

1. variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.
2. it means a type you told is right.

Thanks. I've seen from many mark schemes that only writing 'genetic drift' would give one point. Do you think I will get a point if I just mention genetic drift ?

The intention is to be clear about the answer. You may write 'diffusion' as an answer or you may write 'net movement of particles from high to low conc.' (just an example).
And yes, the term 'genetic drift' gains the mark.

How much will the gt be for the p22 by the way?

what was your meaning of yur post?

 

[maq1996]

I mean what will the grade threshold be for bio paper 22.. any guesses?

 

[MYLORD]

What abt the threshold for bio p21 ?

 

[BeBeskii108]

I think it would be at least 45.

I SUCK AT THIS TYPE OF QUESTIONS.

It c because the radius of the circle covers 50 eyepiece divisions and 100 um is 40 eyepiece graticule divisions so 50/40 x 100 is 125

For p22, it would be around 38, i guess...
