1. ## IB Physics HL P1/P2

This is what I meant
2. ## IB Physics HL P1/P2

I multiplied by pi because when calculating the uncertainty the formula in the data booklet is uncertainty y:y pi is included in the value of y. when calculating the uncertainty I thought we needed to multiply the by value of y. I hope what I meant is clear and not confusing lol
3. ## IB Physics HL P1/P2

Because I put the answer with pi. In the data booklet the formula for the uncertainty shows that you have to multiply by the volume. As a consequence I got pi in the value. Could anyone tell me if this is wrong because I will need it for tomorrow. Thanks guys
4. ## IB Physics HL P1/P2

Is the percentage uncertainty the fractional uncertainty multiplied by 100?
5. ## SL PHYSICS MAY 2016 EXAM:(

Because for the question on the percentage uncertainty I chose the answer with pi because multiplying by the volume that is what I got. If anyone could tell me whether this is wrong I would really appreciate it (I wouldn't like to repeat the mistake tomorrow). Thanks
6. ## SL PHYSICS MAY 2016 EXAM:(

A question, isn't the percentage uncertainty the fractional uncertainty multiplied by 100?
7. ## English A Literature Paper 1

I did the prose as well
8. ## SL PHYSICS MAY 2016 EXAM:(

What did you answer on the multiple choice on the percentage uncertainty, the one on the pool and the one on polarization?
9. ## IB Physics HL P1/P2

What did you guys answer on the multiple choice of the percentage uncertainty? And the one on polarization?
10. ## Physics P1 & P2 (SL and HL) petition

Which exercises in particular did you guys find challenging?
11. ## Physics P1 & P2 (SL and HL) petition

I must say I agree. Paper 1 was tough but I think the questions I couldn't answer were difficult due to lack of studying of that particular unit. Paper 2 had one question per chapter, nothing outside the syllabus. I may be wrong but I think only paper 1 had some things which were not explicitly said in my textbook.
12. ## Economics HL paper 1 Time Zone 0 May 2016

I don't think very much, if the answer is well structured anyways it should't be a problem. I really hope I score decently even though I only talked about supply.....😓
13. ## Biology SL papers 1 & 2, 2016

I got so confused on that questions, I just invented a couple of things which sounded right but I think I lost the points. On the cyclins I connected them to the percentage in S phase, G1 phase and G2 phase. Interphase stages I had no idea because nerve cells did not increase while endodermal did so I couldn't find a justifiable relationship. I also did 6 but for the part of evolution I completely forgot about meiosis, do you think I will be penalised much? I spoke about natural selection, convergent evolution, adaptive radiation, homologous/analogous structures and how different populations evolve differently.
14. ## IB English Literature HL Paper 2

In my class 4 out of 9 who chose the questions did like me. I just hope this is the worldwide trend so maybe examiners will accept it as a right interpretation
15. ## Economics HL paper 1 Time Zone 0 May 2016

I chose question 1 and 4 for 4a I was not 100% sure so I just included the diagram for the LRAS curve and explained the keynesian prespective including spare capacity and all that material for 4b I took a slightly different approach from what I have read. I concentrated on investments for the majority of the answer evaluating pros, cons and how the shift the PPC. I did not really talk about AD and the multiplier because the questions was on economic growth so I concentrated on the quantity and quality of factors of production. Finally I included alternative perspectives and solutions. If I included government investment in education or health care would that be wrong? (Is it considered government spending or investment?)
