IGCSE Biology Paper 3

[flutterby]

I think I did a different variant because dere was nothing about dry mass in my paper( i did Variant 1)
Wat was da answer to the nitrogen cycle processes?
I wrote nitrogen fixation for the first 1 and
          ii)decomposition
             nitrification

[mido_276]

I ALSO DID THAT AND I WAS COMPLETELY SURPRISED BUT ALSO HORRIFIED ABOUT THE DRY MASS QUESTION AS I FOUND NOTHING ABOUT IT
AND ABOUT 2 PROCESS  I WROTE PUTREFICATION WHICH STANDS FOR DECOMPOSITION U WROTE AND NITRIFICATION

[molii]

i hv probably made the stupidest mistake evr!!!!!!!
uurrggghhh
curses!!!!
 

i wrote cell wall instead of cell membrane.. nd guess wad?? i noticd.. nd as soon as i noticd.. the invigilator was like... "candidates, put uR pens down"

 

the bio paper was excrutiatingly long... i hardly got any time to check..
i hd 25 mins left.. i counted hw many questions i hd left nd there were 5.. nd suddenly i notice.. there is a whole new question behind tht.. i hardly got time to read the last question properly altho it was kinda easy....



it was longer than physics..

The exam was HARD!

[aquarian93]

if u remember the last question, first subquestion which had sumthin "Suggest three reasons why not all the energy in the wheat crop is available in animal feed" or sumthin like that i wrote:

1) not all the sunlight available to the wheat crop is used by it
2) animal may not eat all of the wheat crop , some of it is undigested
3) wheat crop may use some of its energy for respiration i.e. for growth or active transport

does that make sense?

overall i thot the questions had too many marks! all 3,4, 5 mark questions..loads of questions were overmarkd n were given like 4 or 5 marks..nyway for the table in the first question, i ticked "Scales/scaly skin" for birds, as all textbooks say birds have scales on their feet, but many ppl in my class sed u didnt hav 2 tick it!

Hey

I cant jude really if what you wrote is correct or not, but it seems ok
This is what I wrote:
1-Some energy is used by the wheat for itself and the process carried out in the plant itself
  
2-Some Tiny unwanted animals or insects such as rats or cockoraches may be feeding on the wheat too thus                                                                                                            
         reducing the total energy available for the animals

3-Some energy is wasted when it is flowing through the food chain i.e from the plant to the animals in the form of                                            heat


And YEAh ur  right tooo many marks for even small quesations

and for the birds YOU HAVE TO TICK THE SCALES IT IS CORRECT SCALES FOR BIRDS ARE CORRECT


Hope I Helped

1 and 3 is same wid me i hope its rite?
i think the other thing i rote, dusnt make sense, so i think ill get 2 marks for it.

the sickle cell anaemia question and energy question in the last page was 5 marks each, it was long and i ws in a hurry, so im scared ill lose a few marks, bt yea i no my answers make sense bt if i had more time, i would explained it better, get wat i mean

yeah it should be ryt LOL

Yeah ofcourse i get, i think everyone or most of the candidates faced a time problem, the exam wasnt that hard, but it like loong and too many 4 and 5 mark questions, the only question i remember was 1 or 2 was the Gene definition and the organ and vessel thingy and the value in the table haha ryt?

i din get anything abt nitrogen cycle, so i gess diff variant

get over biology...it's over

oh ok cool
yea it was full of explanations wid soo many lines, and each question had so many marks, so i was like "wth"
yea only the gene definition and the first and second question. all of the exams this time are extra long *sigh*
hopefully the threshold is low

dudes dudes please, everything you said guys was right, n this exam waz the hardest of all exams this session, in my opinion the exam would've been easier for me if I revised  the first chapters yet, this year's exam is by far harder than last year's. About the time, any problem you face in a question leave it, n solve other stuff that you can solve then work on the hard parts.

Regarding tmrw's exam good luck people, phy is the hardest P1, n wish me luck
