HOW WAS BIOLOGY PAPER 11

[yazan1995]

Hello guys. how did you find the paper? i found it really tricky to be honest . when i went out of the exam everyone was like easy but after we started discussing it turned out to be a really tricky one... moreover, less repeated questions compared to previous years. expecting A to be 28-30

 

[yazan1995]

anyone here to discuss?

 

[white rose]

yup i m here...i felt it easy..but yes there were some confusing options to choose...
i think gt will be 27-30

i felt it was harder than previous years... i was confused in some questions and stuck between two answers.... i agree with you about grade threshold 27-30 seems to be fair. even my teacher said so that it was challenging

yes...same here stuck in two ans...but bio was a lot easier than phy & chem

 

[yazan1995]

oh come on... chem was so easy all the three papers were easy... teacher said about p2 that A could be a 50/60 !

wht did u do for no.of bonds in 700 base pair?

wht did u do for no.of bonds in 700 base pair?

i got D 700 x 3

 

[white rose]

i got D 700 x 3

mee tooo...wht ws ur mean ans?

 

[white rose]

wht did u do fr hydrolytic enzyme in lysosome....where 3 circles were made?

 

[yazan1995]

mee tooo...wht ws ur mean ans?

i got the mean wrong. i choosed only 3

oh god this was the question were everyone had different answers . i think i got it wrong too since majority said golgi apparatus and RER while i choosed only golgi apparatus . what about you/>

for the mean question i think that all the students(1,2,3 and 4) were correct because if you went through the results you will see that there are extreme values that should not be included in the mean . If you dont include these values in the calculation you will get the exact same result as they did. So for instance student 4 had all his results near 20, but there was one result which was 6 this result should be eliminated and not included in the mean.

i told you man . everyone is getting different answers. this paper was challenging and almost every questions needed some work to get the answer. i usually finish within 40 minutes but during this exam i took the full 1 hour to do and knew that i messed up.. hope the GT is low

Am I the only one who did the paper twice? I finished in half an hour and went through it once.

As for the bubble question, the correct answer was D, student 3 only. Because the Student 1 and student 4 calculated the average to be a decimal number of bubbles - how, for example, can you have 1 and a half bubbles? Student 2 simply made a calculation error; it should've been 16 bubbles per minute, not 18, therefore only student 3 was correct.

Hope this helps.

The only one I couldn't do was to do with the denitrifying/nitrifying/etc bacteria carrying out either aerobic or anaerobic respiration :c

i choosed B for that and my teacher said it's B too since in C ventricular distole already started so that was a wrong choice
