  1. I'm gonna play the devil's advocate here for the sake of maybe uncovering some of the things you might have overlooked. In general, the IB for me has been a really formative experience and has given a lot of skills I doubt I would have acquired from the state-funded equivalent at our school. The challenges in it are probably what have been the most rewarding for me, and getting through them has taught me a lot about myself, anxiety, stress and how to deal with them. At the end, they also teach you how to be satisfied with your mark, and to know that what you put in is what you get out. More objectively, the IB gives you research skills and pushes you, in most facets, to engage in university level content, which, should you choose to pursue in university, will undoubtedly be a huge benefit. Its given me speaking skills, through the oral presentations I've had to give in English A: Lit and TOK, as well as writing skills - how to plan an essay, how to argue effectively - and most importantly, how to study effectively. Where I live, the IB is also advantageous in that it does not "scale" your mark according to the rest of your school cohort, which the state-run alternative does (as in, your performance is somewhat dependent on how the rest of the school does, for any given subject). I'm aware that you might not be able to relate to some, or even all of what I've mentioned, but as a final remark, I want to say there's still time. A lot can happen in 6 months, believe it or not, and I think if you put yourself to it, you could completely pick yourself up to a point where you're satisfied with your IB. Ultimately, its up to you. I do not and cannot know what you're going through right now - but what I can give is my opinion. If you need any more help deciding, feel free to send a PM
  2. The biggest discriminator between SL and HL economics is Theory of the Firm, which is itself half of Microeconomics, should you choose to take HL. Calculations themselves form part of theory of the firm, but to answer you question, calculations are probably around 1/3 to 1/2 of HL Ecos, with the rest being ToTF.
  3. Could totally do something on the Winkler method
  4. Seems fine to me. Your IA seems to revolve around friction and mechanics, the former of which is covered only very briefly in the IB syllabus... but the bright side is that any additional detail you go into will probably come off as personal engagement.
  5. Ok, gonna try my best without formatting. What you've got so far with Hooke's Law and SHM is a good start, so now we just gotta start looking at some of the equations. From SHM, you know that a ∝ -x (simple harmonic motion) and you know that F = -kx (Hooke's Law) So, using Newton' second law, which states that F = ma, and equating it with Hooke's Law, ma = -kx This is known as the spring equation, and is pretty much what your IA will centred around: varying the three variables (m, a and k) and observing their effect on simple harmonic motion. Any detail beyond this is optional, but you might want to consider some of the following if you are really interested, or want to lock down those sweet personal engagement marks: dampened harmonic motion, driven harmonic motion, solving the spring equation (requires calculus), friction, multiple springs
  6. Yes, you are correct, they do not offer undergraduate medicine. You can get into postgraduate medicine at Sydney through one of two ways: Achieving a perfect ATAR (99.95) or equivalent IB Score (45), giving you guaranteed entry into USyd's postgraduate course Taking any undergraduate course you like, at any university you like, and maintaining good grades (Distinction or above for most of your units), then transferring to Sydney via sitting the GAMSAT and achieving a high enough score (Graduate Australian Medical School Admissions Test) If you are familiar with the UMAT (the Undergraduate Medical Admissions Test), then its pretty much an extended version of that (6 hours instead of 3 hours), and for university graduate students, instead of high schoolers.
  7. Unless Nature (capitalized) is specifically mentioned in the text, you shouldn't capitalize.
  8. The IB Physics syllabus is specific in saying that Physics SL and HL IAs will be marked indiscriminantly ^This should assuage your fears about having an IA that is "too easy", as it did for me. As well as having confirmation in the syllabus, I personally don't believe that there are topics, for any IA, that are "too easy". There may be topics that are overdone, but ultimately, they can still be done well if you adhere to the criteria of an IA, which are Personal Engagement Exploration Analysis Evaluation Communication But if you still believe that your IA should be "unique", I find that the best way is to find an easy topic and add a twist - change a variable that isn't commonly changed by the generic IAs, do it under different conditions etc etc. Hope I've helped!
  9. no dash on top of a normal neutrino, dash for anti-neutrino
  10. Try Desmos or Google Drawings. Probably Google Drawings over Desmos as reaction pathways don't really have an "equation" - Desmos creates functions through equations. Both are free, don't require a download, and are my go-to for any type of graph. I used Desmos for my Maths and Physics IAs, Google Drawings for my Economics IA.
  11. Here's a good starting point for calculus on arc length: http://tutorial.math.lamar.edu/Classes/CalcII/ArcLength.aspx I'm assuming you're comparing polynomial regression to using calculus as methods to calculate length... but do you have a way to find out how long the road actually is? You need a reference to be able to compare those two methods.
  12. As Martijn said above, radioactive decay is a great choice if you have some background in Physics - it will allow you to incorporate PE in your IA simply by saying "I was interested in the concept of radioactive decay in my physics class, but I wanted to develop it further mathematically". Another example I can think of, but for Chemistry is reaction rates. As the products of a reaction increase, but at a decreasing rate, the reactants decrease, also at a decreasing rate. Though I don't do HL, I have glimpsed over a few articles doing my Chemistry IA about orders of reaction, though I believe they are more to do with rational functions (hyperbolas) than exponential graphs. The pH scale is also a good go-to, as it uses a log base 10 scale.
  13. I am applying for a scholarship at Sydney University next year (its a general, all-purpose scholarship) called Sydney Scholars, and the process of application requires you to answer six questions about yourself and your achievements in a "Personal Statement". Questions 4 and 5 are One of the "Steps" in the "How to Apply for Sydney Scholars Award 2017" also recommends that you should But in general, a lot of the courses (in contrast to scholarships) that you can apply for consider only your ATAR, or ATAR equivalent (seeing as your avatar banner is USA). When applying to Unis, also be sure to check if they offer lower ATAR requirements for international students - they most probably do, but if you are looking into a specific course, always check before assuming you have lower reqs.
  14. I think the modern day notion striking has fallen very much in effectiveness due to the success of preceding strikes. Think of a tool - it grows dull as one uses it. Applying this logic to protest, society's use of it in the past has already resulted in the most essential changes - I.e. black rights, women's rights. I am not attempting to imply that current issues are more or less important than those ones, however, it is the method - through protest - which has gotten 'old'. I mean old in the sense that the proportion of people actively promoting and opposing change has fallen dramatically in comparison to those who are indifferent. Maybe repetitive protesting creates the illusion that issues are less important than they seem, and until society thinks it is threatened again, strikes will be generally ineffective.
  15. Specific case for Economics HL vs SL - this choice definitely favours HL, and can provide a relatively 'easy' 7 for an HL. The apparent reasoning behind this is in the paper 3, containing HL-specific content. How is this different from any other HL? The catch is, paper 3 in economics is VERY basic calculations, scoring you easy marks. Intuitively, having three papers will mean that each paper is worth less compared to SL, containing only two papers. Do well in P3 gives you more room to screw up in P1 and P2.
