Biology Paper 22 Discussion thread.

so it indicates that CIE is so merciless, how would we even answer such things, i'll take details from my sister, she just passed her plab 2 test this march... so u think that reference to air entering and all is nt worthy of getting any credit??

You just realized? bleh I wrote about how the organs won't be able to move properly and that the air entering and leaving fhe lungs eould be reduced since the alveoli would be impaired and that would interfere with the gaseous exchange mechanism as well...

wat u wrote is worthy of credit.........but partial credit...not full credit...

 

[thementor]

I dont remember the exact question, but it asked something about differences in wild and commercial lupins in color and size.

commerically grown lupins

 

[thementor]

a

In the lupins question, I wrote about artificial selection and the change of genes over many generations. Does that make any sense?

artificial selection does but changes of genes over many generations dosent......when the question said commercially, there is no point of writing changes in genes over many generations, Partial credit can be awarded.

CIE has always been merciless.............

Okay guyz...I think 12 pages of discussion wihtin only 4 days....is a lot....I seriously think we should concentrate on our other pprs. What any one has done in this ppr u cant change it, its now gone more marking...

 

[Haris Sal11]

You're screwed. I'm sorry :<
Glucose and urea are ALWAYS reabsorbed back into the body before being excreted as urine. Even your third point is wrong because you've written the answers in the opposite columns. what's your fourth point?

Lol, no, I've written them in the right columns, don't worry. 4th point was BIZARRE! It was about Oxygen -___-

in the Alexis wala ques, last part, i wrote that the external internal intercostal muscles vil b damaged, pleural membrane vil b damaged causing pain wen the lungs rubbed against the ribs n the alveoli vil b damaged, reducing surface area of lungs ... how much marks do u guys think vil i b credited for this ans?

I think your the only one in the whole discussion who was bold enough to say it was easy...I have been studying for it for over 8 months.....and still I made some mistakes.

okay 8 months? wow!! i finished my syllabus in feb but unfortunately the day before paper I felt I knew nothing tau I solved some pastpapers, then i read the whole book (i had read the whole book before atp as well) and i didnt revise again. When I finished the paper I was like, this time threshold will be too high, the paper was too easy and I come here and everyone is like, wth was with that paper?!

 

[Kinza Zimri]

My dad is a doctor (caridac surgeon) and he has books of PLAB, USMLE etc....I looked at one of them and the question was exactly the same, Only the last two parts had been modified, while the first part in the real PLAB paper asked for three organs, CIE asked for 2.

The amusing part is that I got to know from you all that the Alexis question was from that PLAB or whatever those papers are (have got no doc in my family) . I mean, naming the organs was a little tricky there but over all it was our syllabus, directly connected to lungs.

 

[Kinza Zimri]

Aleveolar infection? If the bullet had been above the diaphragm, it would have punctured the lung, and damaged alveoli, reducing surface area for gaseous exchange, resulting in breathing difficulties, Alveolar infection may earn you partial marks.

I wrote the EXACT thing!

 

[Haris Sal11]

his answers are wrong but the columns are correct, the first column was for renal artery while the second was for the ureter.

Wait, More urea, less urea is wrong? :'(

 

[Haris Sal11]

wrong...the lupins question specifically mentioned the word "commercially", since it said commercially the best answer would be the one which wrote abt selective breeding and genetic engineering together.
writing about wild lupins means that youre writing about natural selection etc...that unfortuantely isnt correct.

As far as I remember, this question did not say commercially.

dude i have a pretty good memory, it did say commercially...

yeah it is in our syllabus , but damn one wrong line can affect the whole answer....

The thereshold will be low this time though, thank God for that.
