  1. Though I haven't done Biology myself, I can tell you for a fact that any HL science will be very hard. From what I have heard from friends, I would say there is definitely much more to learn in Biology than in Economics. Here's my perspective on Economics, which I did as an HL: I found Economics to be a huge bore, and taking the wrong attitude into economics is probably the number one 7-killer (i.e., the "easy-7" attitude). I was among one of the people who adopted this attitude for much of IB1 and most of IB2, and it was only until I reached the last quarter of IB2 that I realized that I couldn't just walk into the exam room and get a 7. Elaborating on what I mean by boring, much of the last topic of Economics - Section 4: Development Economics - is immensely boring, as it essentially a huge criticism of classical economics split into thousands of tiny criteria and indicators, and what we must do to ensure "sustainable" economic growth. An equivalence for this would be the Ecology in Biology, or Energy Production in Physics... but its a quarter of the whole syllabus. OK, that's an exaggeration, but what is not an exaggeration is the fact that 15% of your final grade will be assessed via Development Economics in Paper 2, which sucks. Additionally, there is an HL-exclusive topic in Economics called Theory of the Firm, which is part of Section 1: Microeconomics. TotF often generates mixed reactions from those who study HL for two reasons. Firstly, because some regard its content as straightforward, whilst others find it complex. I personally disliked it (but you might not) as it came across to me as the latter - the rest of microeconomics was much lighter and easier to understand. Also, it should be noted that ToTF takes up a significant portion of Microeconomics' content (from memory, it was about a third of the section). Secondly, and more importantly, is because of the way it allows one to possibly*** cut down on the content one learns for Economics Paper 1, in which Microeconomics is assessed. This is due to the way that Paper 1 is structured: there are always 4 question in Paper 1: two questions for Microeconomics and two questions for Macroeconomics. You choose one from each section and answer them. Now, if we focus on the two questions for Microeconomics, we would assume one question is TotF-oriented and the other is non-TotF, as the former is a third of the content and the latter is two-thirds, right?? Well, no. This assumption was what kids "banked" on since the start of the new syllabus in May-13 - common sense would say "TotF = 1/3, non-TotF = 2/3. 1/3 < 2/3. Therefore, study TotF" - and generally, they weren't wrong! That was until Nov-16 came in with no TotF question in Paper 1, throwing a lot people who had relied on that assumption into the dark, as they had not studied any non-TotF content. Apart from TotF and Development, the rest of Economics HL is pretty straightforward, and in general, requires a large, but not unmanageable amount of diagrams to be memorized. About what you said in your post about how you weren't that good at memorizing, perhaps diagrams in Economics will help out? Personally, I found that visualizing the diagram actually helped me remember all the theory behind it, and if not, at least I could make educated guesses as to what each point on the diagram meant. So that's what I would say about Ecos HL... maybe someone who did/is doing Biology HL could offer their opinion on this?
  2. 1. How strict is the 6-12 page limit? According to the syllabus, markers are supposed to penalize you for exceeding the limit. However, markers have been known to be lenient on this limit - some treat it as a rough guide, others are much more harsh. As a result, my recommendation would be to stick to the limit, unless you really, really can't cut down your IA under 12 pages. Saying this, my Chemistry IA was 13 pages, Physics IA was 14, both including bibliography. I expect to lose at least one mark in communication for both. 2. Will the moderator just stop reading at 12 pages? Referencing the quote, there is nothing that explicitly says the moderator will stop reading within reason. I would suspect they would finish reading over 12 pages if your IA is like 13,14 or 15 pages, but if your IA is like 50 pages long, they might skim the rest lol. 3. Title Pages We were told not to include title pages in our IAs because they weren't necessary - all your details will be included in a coversheet when your IBDP co-ordinator submits them digitally. As for the research question, just have a heading and type it out: If you do feel the need to include a title page, I don't think it would count towards the limit. Good luck with your IA!
  3. 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
  4. 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.
  5. Could totally do something on the Winkler method
  6. 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.
  7. 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
  8. 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.
  9. Unless Nature (capitalized) is specifically mentioned in the text, you shouldn't capitalize.
  10. 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!
  11. no dash on top of a normal neutrino, dash for anti-neutrino
  12. 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.
  13. 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.
  14. 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.
  15. 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.
