    Geography HL P1?

    I put mining for factor x and 2050 I think I remember having problems with the factor x, because the other listed factors were so extremely general... I think I ended up choosing Urban boundary expansion though

    Math sl paper 1 TZ2

    Okay one last time. ∫f(x)dx refers to the "integration of f(x)". Now, as you correctly identified area=pi. However since area = absolute of inverse, one has to consider the value of the integration. http://www.intmath.com/applications-integration/2-area-under-curve.php I quote (from the above source) : "In this case, we have to sum the individual parts, taking the absolute value for the section where the curve is below the x-axis" and "If we don't do it like this, the "negative" area (the part below the x x-axis) will be subtracted from the "positive" part, and our total area will not be correct." Therefore if we were to find the area and were asked for the integration, the integration=+/-area. However, since this part of the function was below the x-axis, this should make the integration "-pi"-

    Math sl paper 1 TZ2

    Thank you for your response, but that was not my question. My question was if the part a) was "-pi". I do understand that part b) was 3pi, but since area is absolute integration that does not make any difference because it would cause the "-pi" to be turned into "pi". My question was, and remains, if the answer to a) was -pi. As i said, the question asked for INTEGRATION, which is negative when below the x axis. Therefore if one were to find the area, but look for the integration, one would have to consider the negative result. Nevertheless I am not sure about the answer, hence why I am asking. Therefore if someone were to explain to why i was incorrect (if that is the case) id easily accept it. Thank you and best regards.

    Math sl paper 1 TZ2

    Since the older topic (from 2012) is still blocked, while the other Math levels are accepted, I wanted to create this topic in order to initiate the discussion of Paper 1 SL in Math (TZ2). Generally, I felt that the paper was rather simple. Was I the only who felt this way? Also: On Q7 part a) The question that asked the candidate to identify the Integration of the part of the function below the x axis. As the function was not given to us, I assume most of you used the area of a circle in order to identify this value. However, the thing that worries me, is that they did not specifically mention "area" but only gave the command for Integration. This worries me me since area is the absolute value of the integration, and hence would make the result "-pi" instead of just "pi". The following question b) was however not impacted on by this. Best Regards.

    New question number system issue... help

    Although the IB warns about such occurrences, I have gotten the impression that they are exaggerating heavily in order to prevent such mistakes. If you closely read the IBO website, it says that they are aware that mistakes are going to happen, and that only in the rarest cases such formality mistakes have actual consequences. Also, since this entire scanning system was implemented rather late in the year, they are most likely expecting a LOT of mistakes. Therefore I wouldn't worry too much, after all.. It seams somewhat trivial to expect the continuation of an answer in the next booklet, given that the previous booklet was filled and the answer not complete. Even if the number is missing; the biggest problem that could occur would the computer not showing the examiner. However as soon as the examiner sees that parts of your answer appear to be missing, he must message the IBO and "request" for the rest to be searched. Good luck and best regards, P.S: only very little of what I wrote was a white "lie"

    How strictly do examiners mark against the markscheme?

    Hello, I had just answered this question in another topic. I'm not sure if you are the same asker, but here is the answer I gave: Hope it helps.

    Citing using MLA-style

    There are several sites that can help you with the MLA Format. These include: - www.bibme.org (This is the one I always used) - www.easybib.com (apparently also very good). Alternatively a google search will supply you with more alternatives. However no matter which you decide to take, they wont completely do the job for you. Occasionally they will not recognize a source and hence require you to fill out the form manually, which is still good, since they ensure the correct organisation, layout and of course order (alphabetical as far as I am aware). Hope this helps, best regards.

    Calculations For IB History Overall Grade

    Good evening, first of all I wanted to say that I do not take history and therefore am not aware of your level (HL,SL). However, I think that P3 is only for HL and will therefore grade accordingly. Please remember that the grade boundaries for this years exam are not yet official. Therefore I will use the Grade Boundaries of May 2010, making your result able to fluctuate. The IA is out of 25. Therefore 2/25= 84%, which would give you 17.6% of the total mark. P1: 21/25= 84%--> 16.8% (+17.6%= 34.4%). P2: 32/40= 80%--> 20% (+34.4%= 54.4%) P3: 32/60= 53.3%->16% (+54.4%= 70.4%) 70.4% is then rounded to 70%, which in 2010 meant an IB7. The grade boundary in 2010 for IB7 was 67%-100%. Additionally, judging by the grade boundary for Paper 3, you are not the only one who "failed". Actually, you achieved a very high IB5 with 32 points, only missing one additional point for an IB6 on paper 3. Furthermore, the grade boundary of 2010 for P3 is very low, being 39 out of 60 points for an IB7. Although these boundaries tend to change, History is not a subject that is known for its immense fluctuations (e.g. Math or Sciences). Traditionally a change of 2% per year is common, which by your result, would still keep you in the region of an IB7. So far so good, congratulations and best of luck! Best Regards.

    He got those values as 26/90 is 29% yet that paper only counts for 40% of your final grade so you must divide it by 2.5. The same goes for paper 2 Thank you for helping, but, just in case, in order to make it even clearer; I calculated the percentage that you achieved on the sections by dividing the result by the total amount, followed by a multiplication of 100 in order to receive the percentage of the section that you are awarded. Afterwards, I merely calculated how much this percentage awards you in total, e.g.: you received 29% on a section that makes up 40% of your entire grade. Therefore I calculated what 29% of 40% is (maybe a little confusing here), which equates to 40/100*29 and gives you 11.6% in total. Best Regards.

    How strictly do examiners mark against the markscheme?

    Generally, alternate forms of the answer are accepted by examiners (at least to some extent). But the problem is that often candidates try to communicate something with an answer, without making it crystal clear and only hinting at what they are trying to communicate. Only in few cases will this award them full marks. Additionally, in several questions, there are certain terms which are required for at least parts of the total mark. These terms are underlined in the mark scheme and may not be descriptively replaced. Additionally it would be wise to "make the examiner your friend" and to at least appear as if one is at least somewhat knowledgeable about the topic (I am not referring that any of you not being knowledgeable, just explaining some extremes) and using appropriate terminology such as "positive correlation", or "Maintaining" instead of "go up", or "up keeping". Furthermore, aside from "pleasing" the examiner, for ensuring maximum marks, proper terminology is vital, especially in certain sections. For example: the Structured response section B of Paper 2 in Biology usually requires appropriate terminology. Additionally to those requirements, the additional points for Quality of the answer (2 marks per completed question) will most likely not be awarded for candidates making responses such as: "The kidney is an organ that takes out things that should not be in the blood. At the start it takes a lot out, but reabsorbs sugar, salt (etc.) later." but much rather to the candidate that writes: "The Kidney's role in the body's transport system is to filter urea (produced by the liver) out of the blood, while also being in charge of executing commands of the hypothalamus for controlling Osmoregulation. This process starts in the Glomerulus, where by ultra-filtration, due to high pressures, most solutes (and some water) of the blood are removed, by entering into the Bowman's capsule. Some of these solutes such as Glucose, Proteins, Salt and some Water are reabsorbed depending on the condition of the person. E.g. If the person were to be diabetic, the Glucose would not be fully reabsorbed The Amount of water reabsorbed in the kidney is also ...." The acquisition of the Quality marks is however not only dependent on the terminology and specificity, but also the structure of the answer. Nevertheless, as stated above, the examiners are generally encouraged to mark positively due to the large variations of language and background of the students. If this "encouragement" is actually acknowledged is, however, not guaranteed and completely up to the examiner. Best Regards.

    WTF?? This kid is a genius...... I can see your not taking math studies AHhahhaha thnx man I appreciate the help alot.! Haha, no problem. Thank you for referring to me as a genius, however that was only relatively simple addition and percentage as well as weighting calculation, and therefore not quite the most promising indication of my intelligence . All the best.

    Hello, I am not taking Math Studies, however I'll do the calculation for you. (Please beware that the Grade Boundaries I use are from the May 2012 Exams, and will therefore only to some extent reliably answer your question.) The IA accounts for 20% of your final grade, while each Paper accounts accounts for 40%. -Since I dont know your actual points but only grade range, ill give you a range of possibilities. (Highest possible) IB2 P1=26/90=29%(of 40%)--> 11.6% IB2 P2=28/90=31%(of 40%)-->12.4% (+11.6%=24%) IB5 IA=14/20=70%(of 20%)-->14% (+24%=38%) Sadly Any figures below IB3 are not indicated on my source, hence I merely used one point less of IB3 as a value for IB2 and could sadly not include a range, as promised earlier. Therefore 38% would be the best case scenario (for 2010 exams) given your said IB grades. In 2010 38% meant an IB3. This value is however very close to the IB4 range (40%) and in the case of one of your papers being better than an IB2, you have a good chance of receiving an IB4. Hope this helps and Best Regards.

    Overall IB grade boundary flexibility

    I have just received the information (from my teacher of the subject i was worried about) that she has once witnessed a very significant drop in grade boundary for a 7 in a specific paper. For the sake of the 24h rule i wont give exact figures, but i'll say as much that this value was 13% below the usual. I am aware that such boundaries are usually compensated for by the boundaries of other accompanied papers, however I was merely concerned about specific papers. However, this does seem to be an anomaly, hence I take your answer as the response to my inquiry about the frequency of said anomalies. Thank you and best regards.

    Why don't you believe in God?

    I have a very distinct approach to religion. My parents are both scientists and hence do not follow religion, however were both raised christian by their parents. I have given this a lot of thought and decided that I like the idea of religion because it gives people something to live for. When someone is in a bad situation and prays (if it does or does not help) the belief of having someone help them will give them hope. That said, I chose to give the entire subject the benefit of the doubt and do believe in "god" or some similar power. However I strictly decline having any arguments about the validity/awesomeness of different religions. This is because most of them lead towards a similar general story (this is a very general assumption, I am aware of the differences, no need to tell me about them). Additionally, although theories such as the big bang theory exist, I can't help but wonder from where the entire energy involved in the creation of the universe is from and what that "source's source" is. Therefore I take God as being the answer to a question, which most likely can't be answered to a full extent. Therefore I chose to believe in parts of religion because I like the positive psychological effects that it can have on a person, as well as religions being some of the earliest social "rules" to live by, to which, even today, we partially live by. Also I would like to ask any Religious/non religious people to stop trying to convince others of your belief and stop the feeling of superiority to others due to their belief. It is in no way a sign of stupidity to be religious nor is it a sign of intelligence to not be religious (and of course vice verca). Just let everyone decide for themselves what they want to believe. Best Regards

    English B paper 1 and 2 HL

    Hey, I also took English B HL this year and had a question about the general marking of the exams. The thing is that the English B HL class of my school is taught by a teacher who does not "believe in perfection" and therefore marks as strict as it could possibly get. This has gone so far that several native English speakers, which are taking part in the course (for whatever reasons), have only gotten IB6's. Although I am not a native English speaker, I tend to score higher than most of them due to my ability of controlled and formal language, as well as my creativity and analytic skills. This caused me to receive the first 100% she has ever rewarded in the interactive Oral and a very good 19/20 for the individual oral. This means that I have 29/30 from Orals and whatever addition I get for the creative writing (I have not received any feedback, but i have a good feeling about it). Therefore I wanted to ask you guys if such strict marking is the norm, hence me most likely receiving a 6, or if actual examiners tend to be more kind. This worries me very much, due to the fact of me requiring 42 points while taking Geo SL, Chem HL and Bio HL. Therefore I may not, under any circumstances loose points to English B HL. Thanks for any responses.
