  1. For the HL creative writing piece its 150-250 words.
  2. At my school, teachers generally recommend the following for the IA: to have a cover page with the title of the work, the word count (if required), the examination session (e.g. May 2018, November 2018) and the subject.
  3. 1) I think that it's not fair, as when I ask for something I feel I should receive some kind of explanation. 2) I think that I have been raised as an independent thinker, which has allowed me to question a lot of the things that people have taught me and to avoid being manipulated into doing things I don't want. 3) I don't think so. 4) That life is not just about school and grades, but also about enjoying oneself. And that happiness is more important than success.
  4. Hi everyone, I'm struggling with my calculus homework on the rates of change. I have a number of problems I need to do, but I don't understand at all how to solve them. For the example below, could someone please walk me through the exact steps (and why you're doing them)? A spark from a fire burns a hole in a paper napkin. The hole initially has a radius of 1cm and its area is increasing at a rate of 2cm²/s. Find the rate of change of the radius when the radius is 5 cm. Thank you very much in advance for helping me out.
  5. Dear Clara, You can of course do your Business SL IA on motivation, with a research question along the lines of: To what extent would company XYZ benefit from Y theory to improve motivation of its staff? However, I heard that B&M IAs that focus on human resource management rarely score high. This may be because of the lack of secondary sources on HRM-related issues (most companies publish more about finance or marketing) or simply because examiners prefer to see more "rigorous" financial and marketing concepts. However, if you are sure you can do this well - with sufficient and varied secondary sources for backing up your claims, then I don't want to deter you. Regards, astonky
  6. Hi, I'm not doing French ab initio, but I'm doing Business Management SL, also with Pamoja. Many students in my school (me included) are struggling with our teachers, because they are not responding within a reasonable timeframe to our questions and problems. For instance, I finished my first draft of my IA two weeks ago, and have been asking my teacher the same question 3 times (starting from when I planned the IA) and still haven't got an answer till today. I suspect that for many teachers at Pamoja they are too involved with their day-to-day teaching at their schools and thus not very flexible with their schedule. Also, getting 70s and 80s in any language is a good achievement! If you feel like your teacher is grading you too harshly (and incorrectly) bear in mind that they might well have been doing this late at night - or have learnt certain grammar rules for French, but not their exceptions. Therefore, I would not worry too much. Instead try to focus on perfecting/learning french outside of Pamoja, as this is what will ultimately let you speak/read/write and do well in the final exams. Hope this helps and best of luck, astonky
  7. Ok, thank you so much for your help.
  8. Ok thank you very much, I now managed to solve part 1. For part 2 I am slightly confused about why you need both the poisson and the binomial distribution. Would you care to explain that further?
  9. Hi, Could anyone please explain how to solve this type of question: In a ski resort, the probability of more than 3 accidents in any day at the weekend (Saturday and Sunday) is 0.24. Assuming a Poisson model, 1) Calculate the mean number of accidents per day at the weekend (Saturday and Sunday) I got to the point that P(x>3) =0.24 and P(x<3 or x=3) = 0.76. How do I continue from here? I also know that the answer is 2.49. 2) Calculate the probabilit that, in the four weekends in February, there will be more than 5 accidents during at least two of the weekends. I am completely lost as to how to approach this question. Any help (with clear explanations) is much appreciated. Thanks!
  10. I agree with @shellziess about Geography and Economics. The same holds true for Geography and Business (which I am both taking so I might be a bit biased). Economics may help you more if you're thinking about going into finance, market analysis and government policies. Economics is more of a macro-level subject, while Business focusses on the micro-level decisions that enterprises face. Business management may be more appropriate if your interests lie in marketing and entrepreneurship and you enjoy analysing the problems and opportunities a specific company faces. @SomeoneYouDon'tKnowWhether you want to or should take Psychology or not depends on what line of work you want to pursue after a business degree. Psychology is seen to be a narrower Group 3 subject by some people (I don't know whether this is true) and from what I've heard it focusses a lot on analysing different psychological studies. Take my words with a grain of salt, but I think psychology may help you in marketing topics of a business course. Though this obviously depends on the topics your school does. In conclusion, Geography may be more versatile, while Psychology may be viewed as more unique but sometimes also more restricted. If you need to make a choice, try to attend all classes of interest for the first two weeks and then make a choice (this should be possible at your school as per IB regulations).
  11. I recommend you decide on a clear cut off point each day after which you will do no more school work, and just relax, or hang out with friends (ie. do what you like).
  12. @SomeoneYouDon'tKnow I agree with @shellziess. I would not recommend you to take both HL Economics and Business Management at the same time. I would pick the subject where you think the course looks more interesting, or if your unis have a preference for one, I'd pick that one. Even though you're fairly sure you want to pursue a business degree after uni, you might enjoy some more variety and one of the two subjects should suffice for universities (in some countries Economics has a better reputation that Business management, but that depends). Maybe you want to choose a different subject from Group 3, such as Psychology or Geography, the latter being linked in some parts to the business syllabus if you take it at HL. But if you are sure you would enjoy both Economics and Business (after looking at the syllabi) you may want to stick with both subjects.
  13. Thank you so much!
  14. @kw0573 Thank you so much for your help. I haven't seen hypergeometric distributions before. I understand everything up to the last step when the final value is calculated (the substitution of variables and their logic is clear to me. But taking the first problem, how do you get from P (X =2) = ((10 --2) ( 10 --3)) / (20--5) = 0.087 ? Because if I use combinations I get a different result of around 0.34. These are the steps I did: 10 nCr 2 = 45 10 nCr 3 = 120 20 nCr 5 = 15504 45*120 /15504 = 0.348 Would you please tell me where I went wrong? Or did I completely misunderstand how to do hypergeometric distributions? Info: I did not know how to write the 10 above the 2, and so on for the binomials on this forum, so (10 --2) is supposed to stand for 10 nCr 2. The rest seems to be clear to me once I understand how to do these hypergeometric distributions.
  15. @themthem Your subject choice depends on what you want to do, which you find more interesting and which has the better teacher. I take Geography HL and Business SL (online) and I like Geography a lot more than Business. This is partly because we have a great teacher, but also because there are a lot more relevant geography websites and the theory is easy to understand. In business, I sometimes feel that the theories we study are not nearly as reliable (or used as much) as in geography. In geography, you'll learn about population change, economic and social disparities, environmental geography and whichever two options your school selects. In business, you'll learn basic finance (balance sheet, profit and loss account, profitability ratios), marketing (4Ps, etc.), human resources, and operations management. If you want to go into science/research I would recommend you take geography - the methods are similar to scientific procedures, whereas if you think about working in a company you might want to choose business. In my opinion, geography is the more versatile choice of the two.
