UCL14May Posted May 10, 2014 Report Share Posted May 10, 2014 How did everyone find it? I think the grade boundaries for paper 2 will be really high... I really hope not. 1 Reply Link to post Share on other sites More sharing options...
thirdculturekid Posted May 10, 2014 Report Share Posted May 10, 2014 (edited) I found these exams so difficult (especially paper 2)! I just could not understand the data base question about the UV rays and the plants. I felt as though I knew all the content for the exam perfectly, but that question just completely threw me off :/Did anyone feel the same? I'm really hoping I'm not alone on this, and that the IB will adjust the grade boundaries! Edited May 10, 2014 by thirdculturekid 1 Reply Link to post Share on other sites More sharing options...
I3lackAngel Posted May 10, 2014 Report Share Posted May 10, 2014 I found the first question on paper 2 easy, but the pictures in the other questions were really bad, so I doubt that I will be able to get a 7 :/ Reply Link to post Share on other sites More sharing options...
battlescarves Posted May 10, 2014 Report Share Posted May 10, 2014 (edited) Most people in my class said they found both papers to be really difficult. Personally, I didn't find them to be too bad (no idea why my experience seemed to be so different from everyone else's). The last question in Section A of Paper 2 threw me off though! (The table with ratios, I had no idea what to do) Edited May 10, 2014 by battlescarves 2 Reply Link to post Share on other sites More sharing options...
LeonieIB Posted May 10, 2014 Report Share Posted May 10, 2014 Are you kidding guyss? It was so easy! I'm just kidding. Just like some people I have spoken to so far said, it was the hardest biology exam I have done in these two years.Do you guys know if the IB adjusts the grade boundaries on a global scale, or is it different for each group of students/class?I found these exams so difficult (especially paper 2)! I just could not understand the data base question about the UV rays and the plants. Did anyone feel the same? I'm really hoping I'm not alone on this, and that the IB will adjust the grade boundaries!I agree with this. I did not like the data response questions that were both on Photosynthesis! Somewhat more confusing than the practice ones I've done. Reply Link to post Share on other sites More sharing options...
IXUS2000 Posted May 10, 2014 Report Share Posted May 10, 2014 (edited) I got a mag value of x5500 (the length of that scale bar was 11mm, so thats why). I hated that microscale picture, which I got wrong :/ It was the rER, and apparently it said so in the link of the source underneath the picture... I thought it was the Golgi apparatusI agree, the data base question was tough. But I actually think Section B was not too bad, I did the last one on blood glucose and energy in the trophic levelsAlso, on P1, the question on repolarization and sodium potassium, what was the answer? I took C (when it was in the process of going down, but I am not sure) Edited May 10, 2014 by IXUS2000 1 Reply Link to post Share on other sites More sharing options...
LeonieIB Posted May 10, 2014 Report Share Posted May 10, 2014 (edited) On paper 2, it asked to identify a certain structure and its purpose (referring to a microscopic image scan). I was not sure and said it was a cell wall. What was it actually?There are so many questions I want to ask but don't want to spam the thread. We need a chat group you guys!

It was the RER (rough endoplasmic reticulum), because you could see blurry ribosomes attached on its walls. I got a mag value of x5500 (the length of that scale bar was 11mm, so thats why).

I took C (when it was in the process of going down, but I am not sure) When the line is going up, that's depolarization, going down is repolarization. But wasn't the question asking about returning to resting potential? Oh gosh maybe I misread it Reply Link to post Share on other sites More sharing options...
linaalsaheb Posted May 10, 2014 Report Share Posted May 10, 2014 I found the table with the gentics question kinda tough why did we have to fill the ratios in two sqaures!! 2 Reply Link to post Share on other sites More sharing options...

thirdculturekid Posted May 10, 2014 Report Share Posted May 10, 2014 Yeah that's what I put too. Ouf! Correct me if I'm wrong, but is it true that to get a 7 in Paper 1 we can only have 2-3 questions wrong? Does anyone know? Reply Link to post Share on other sites More sharing options...

Correct me if I'm wrong, but is it true that to get a 7 in Paper 1 we can only have 2-3 questions wrong? Does anyone know?you can get up to 5 mistakes. If the 7 is an 81 then divide any mark you want by 30 (according to paper1) then multiply it by 100, if the outcome is more than 81 then it's a 7 1 Reply Link to post Share on other sites More sharing options...

I'm really hoping I'm not alone on this, and that the IB will adjust the grade boundaries! They take all of the result and make Gauss curve and then calculate so that some percetage of the population get 7, some 6 etc etc so it is very possible that if the exams are hard and a lot of students get lower results, the grade boundries will also be not that high, so no worries 1 Reply Link to post Share on other sites More sharing options...

Oh gosh maybe I misread it I got D because I think it returned to the resting potential after repolarisation I took D as well (actually revised that section right before the exam, so I am 99% sure it is correct) and I said that it was an endoplasmic reticulum, but it was really confusing. Especially since rER are usually close to the nucleus, but it was next to a mitochondria in the picture. 1 Reply Link to post Share on other sites More sharing options...
ibnerdcando Posted May 10, 2014 Report Share Posted May 10, 2014 My paper was TZ1 im guessing you all had tz2...section b on paper 2 was much easier than paper 1 1 Reply Link to post Share on other sites More sharing options...
IB . Posted May 10, 2014 Report Share Posted May 10, 2014 I agree with ib nerdcando. The SL paper 1 and 2 for TZ1 was surprisingly easy for the bio kids in our school. The section b questions were like a gift! 1 Reply Link to post Share on other sites More sharing options...
