    Can I change my one of my Hl class to Sl class?

    You can definitely go from HL to SL for an exam. My school has about a dozen (if not more) Math HL students who do that every single year. Just let your teacher and coordinator know. Bumping a SL up to a HL might be more tricky, because there's a huge difference in content, and your IA will also need to be assessed by a different standard along with your predicted grade. There has been allowances of this in the past, but you probably would have to convince your teacher/coordinator, and you should do so at your own peril because SL vs HL content for sciences is very different.

    Physics IA Format?

    There are quite a few exemplars online, but I guess I'll share how I formatted mine: Intro, method, data, analysis, errors+limitations, eval+conclusion, references Good luck!

    ITGS EE: Surgical Simulations

    IT and medicine/surgery is a very popular, and also very important topic in the course, especially moving forwards. It also has a myriad of topics on both the IT and GS side, from different technologies to its ethical impacts as well as how it will be implemented, used and perceived. Starting with your question. "To what degree" is not a common RQ beginning. I'm not saying it can't be used, it's just that IB and all past papers seem to favor "To What Extent" although there's hardly any difference between the two. Your question slightly favors the broad side, as it uses the general word "effective". However, by writing a clear abstract and introduction in your paper about what you are going to define as "effective" will probably make your questions feasible, so I think you can leave the RQ. The immediate questions that emerge from this topic is the bate about technological bugs or shortcomings, which can transition into the argument of who is responsible. You can talk about the risks and rewards, give some background on the development, talk about how this is going to move forward, and most importantly, what the view on this topic is within different communities from differing points-of-view. However, this requires massive amounts of legit data and research, so 10 sources may not be sufficient (it depends on what sources they are). ITGS EEs can have upwards to 40 to 50 sources, given its reliance and dependence on facts, data and opinion. Conducting primary research, such as interviewing patients, doctors, or developers of this technology will also significantly help your paper, so I suggest doing this if this is a possibility.
  4. Ooook now I don't think I'm qualified to advise you, because I know nothing about this subject. I think it may be *slightly* better to narrow down industry and area, it makes it easier for you to write a good paper. However, for your 4000 words to have dimension and your paper to be good to read, I think you should narrow down the question but broaden your paper by exploring it form different aspects, if that makes sense. Again, take what I say with a grain of salt because I don't know too much about the subject. Good luck!
  5. Finally an ITGS EE, yay! First of all, "to investigate" is not really a question, and so not that suitable as a RQ. ITGS EEs usually use TWE or How to begin their questions, and in your case I think TWE would work better because it allows you to do some analysis and come to a reasoned conclusion. One way or another, you either need to find very legit data or conduct your own surveys, as ITGS EEs thrive on primary research (I did 2 interviews). Notice how you said "draft due date". I'm sure that's flexible enough for you to do good research and submit a good paper. Specifying area/region and a type of business can make your paper easier OR harder to write, and add holistic value to your paper as well as some personal engagement, although it's hard to say if it will definitively make your paper "better" or "worse". However, specifying region and/or business would mean that you would have to do specific kinds of research, which could be easy or hard, depending on your situation.
  6. I think the criteria uses some big but vague word like "concurrent with curriculum" or something of that sort. So the safe way is to do something that you can classify into one of the topics of the course, but the content of it should probably be 50% above the curriculum (I did stats, using some distributions taught in the course and some that weren't). Like kw said, calculations by hand won't add marks, there's no criteria for effort. However, if IB feels that it's something better done by computer to give a clearer mathematical representation (ESPECIALLY when it comes to graphs or anything that is required to be neat/precise), it's probably more likely that you'll be docked marks instead. If you have any burning questions, asking your teacher is probably also a good idea.
  7. The point of using sources is add credibility and backing to your own writing. I highly doubt that the usage of such sources is allowed, and even if they are, they are definitely not recommended,

    Math IA: must the data be real?

    I'm pretty sure they have to be "real" (how do you determine real data anyways). The reason being is because you are attempting to find a trend (or non-trend) within the data, at least I'm assuming that's what you're planning on doing. If, say, one person fabricates the data, then there's a pretty good chance the data was made to conform to some sort of trend. "Real" data is the safe way to go. You should probably work on authenticating the data, and ask your math teacher.

    Boxer Rebellion resources

    As the Boxers were seen as the enemy by the eight nation alliance and therefore much of the West, I doubt you would find many Western publications that focuses on the details and aftermath of China after the rebellion. However, if you can read Chinese, there will be plenty of resources detailing the implications of the rebellion, as it was a significant part of Chinese history that contributed to the next period of wars and instability within China. I'm sure there are translated works of these resources, although finding them may not prove to be easy. Hope that helped. Good luck!

    Given that I took HL and barely understood that article, I'd say the math is definitely up to standards. The only thing is, Markov chains and statistical modelling is closely related to ComSci (I had a friend who did something similar, and kinda got screwed). However, as long as you focus on the statistical aspect (I wrote mine on statistical modelling and baseball), and talk about the the characteristics of the models with reference to mathematical concepts (dispersion etc.), then it should be fine. Definitely a very interesting topic, best of luck!

    Physics IA

    Database IAs are allowed, but I wouldn't recommend it for physics, as it is a very experimental and applicable science. Most database IAs are done in Chemistry. However, if you conduct an experiment and compare it to information from a database, that would be a fine idea.

    It would be helpful to know what math you're taking, so we can see if your proposed idea is commensurate with that course. Anyways, predictive models definitely involve a decent amount of mathematics. However, you should cautiously approach it, as it is very easy to venture into physics and/or computer science when talking about application towards a sport like tennis. I'm not sure what you mean by "ease of use", but that sounds very much like a simulation design topic, which would involve more code than math. Accuracy would be quite simple to calculate with a few probability formulas, so unless you can put a spin on that (no pun intended), I don't think the math will be sufficient enough for an IA (well...maybe for studies).

    Math HL IA topic too bad?

    Ok dude. Given this is Math HL, the math your IA requires needs to be quite rigorous, at least on par with HL curriculum and preferably a little beyond as well. So far you have...functions? Personally, I don't see this meeting the criteria (it's online, looking at it can be quite helpful), and I really don't know how you plan on filling a 10-12 page report on it. Hopefully I'm just missing your central idea, and it all goes well. IF you feel your idea doesn't warrant a good mark according to the criteria, then a potential area could be changing some parameters of the functions for different results. Even that feels way too simple for HL. Don't constrict yourself to a narrow area of maths. Broaden your views before you settle down. Good luck!

    IA Physics help?

    Guitar strings is actually pretty common as far as I know, I have a few friends who did it. I guess you can investigate harmonics and oscillations and whatever, and I heard this one kinda cool thing about changing the temperature of the strings and plucking them. As for global warming and energy, I guess you could attempt something with water, wind or solar power. A battery of sorts would also maybe work, although that strays dangerously into the chemistry realm. As for taking data from a database and analyzing it, it's more common for chemistry, so there aren't a lot of examples for physics. This should probably be your last resort. Hope that helped, good luck!

    Is this a good course selection ? Please Help !

    Since you have three languages and only one science as of right now, your courses already put you out of contention for almost all engineering programs (in North America and UK), where both chemistry and physics are pre-requisites. Hence, Math HL would be unnecessary, since engineering is the only faculty that really really requires/recommends the course (except certain math and physics faculties). However, it is always possible to drop from a HL course to a SL course, or drop for the exams, so you can go that direction as well. The most important thing is to have a goal of what you want to do in university. Once you do, course selection will be a lot easier.
