  1. I'd be willing to provide a quick glance over and give you some overall feedback if you want to PM me, but I can't be too precise.
  2. Answer in pdf form: Answer.pdf
  3. Hinges quite significantly on what career path you wish to pursue. Different choices at different universities require different HLs at appropriate scores.
  4. You can do an irregular diploma, where you exchange one subject, such as a second language, for a science, or just tack it on as an additional subject. I'm not too sure of the exact process, but I think you need to write an essay to the IB explaining why for the former.
  5. My answer's in the attached file. Answer.docx
  6. You can get at least a D in an EE by simply just following a good structure, not making any silly mistakes, and following the mark scheme closely. Of course, I'm pretty sure that you want to do better than this, so here's my advice. According to the IB EE guide, "Chemistry is the science that deals with the composition, characterization and transformation of substances." Your EE investigates the transformation of a substance into something else, and also deals to some extent with the composition and characterization of limescales, so I'd say that your topic is related to chemistry. I can't help you much in regards to the IV - maybe others can. I'd say that your research question needs to be more refined. Maybe specify what is being softened, what the resin beads consist of, and the range of temperatures you're investigating (if you do choose to do temperature).
  7. I'm fairly certain that the physics HL course is specifically tailored to accomomdate students of all math levels. You need no knowledge of calculus to do well in the examinations, and the most complex math simply involves a few logarithms and a bit of algebra here and there. So yes, I'd say that it's definitely possible to do math studies and physics HL. Just make sure that you understand the concepts and reasoning, and you should be set.
  8. I'd say that organic chemistry is the most difficult topic, because it requires knowledge of most of the syllabus to truly understand, which is why it's usually left as the last topic in my school. As for selecting math, chem, and physics all HL, I'd definitely say it's doable, as I have this current selection (with Further Maths too), and I'm not finding them really difficult. However, I would like to mention that difficulty is ultimately quite subjective, and some things that you may find easy others may find difficult, and vice versa. There are those who would find such a subject combination very difficult indeed. The best advice I can give you as a 10th grader is to simply just read through the topics beforehand, especially (but not limited to) during the summer break. It's what I did for these three subjects, and it's helped me tremendously. It may also help you realize whether or not you actually can properly learn all the material in two years time. Having these HLs does grant the most versatility in selecting an appropriate engineering course though - I'd imagine that you'd be free to specialize in virtually any area you wish to, from mechanical engineering to electrical engineering to chemical engineering.
  9. It may help somewhat, but you may want to state it near the end. Check with your supervisor on this. Glad to be able to help.
  10. Seeing that you're not doing an experiment, this would be more related to theoretical physics, which is more math-based than anything else. I'm not too sure if this would fall completely underneath physics as a result. You may also need to consider the motion of the moon in itself too, and what angle the asteroid is coming in at. For example, a head-on collision opposite to the direction of the moon would have different impacts compared to a head-on collision in the same direction of the moon. As for your research question, I think it's sufficiently focused, although I'd work on the wording a bit (maybe mention that you're looking for minimum mass and velocity to be more specific). I don't think that a consequences section is truly necessary - it sort of detracts from your RQ, and remember highly focused EEs are generally the best.
  11. If they were taught to you in class, then I doubt that you need to cite them. If you obtained the ideas from another source besides class or you teacher, however, you may need to reference them. As for your second question, yes I'd imagine it'd be possible, and that Turnitin may also spot some plagiarism that other systems cannot.
  12. It seems that you're attempting to use two definitions for one thing - both linear mass density and the length are indeed similar, and describe similar things, except they use different units and concepts. I'd recommend sticking to one definition to make your reasoning clearer, and to simplify calculations. The topic is probably OK for HL - it's more complicated than the regular pendulum, which is good. Note that your discussion and analysis should also be of HL standard, not just the topic. If you don't have a very strong correlation, then put this in your discussion and try to figure out why.
  13. If you don't want to drop math HL, then you may need to work harder at it. It's definitely necessary for most engineering courses, as you rightly mention. Some tips from me that may be helpful: Work on becoming better at math overall. For especially difficult problems, do not just give up and look at the answer keys. Instead, work on them as long as you need to, until you get the answer. It's through this method that you truly learn math, and ways to develop new techniques. Review past papers. At the very least, you'll get used to the format, which is important. Questions are also relatively similar from year to year - there tends to be quite a bit of calculus, and almost always a complex number/vector problem chucked in somewhere. Try to really understand the math used, instead of doing a plug-and-chug with examples While most high school math is plug-and-chug, it just isn't enough for a 6 or 7 in HL math. You may sometimes face a relatively novel problem in the HL math exam, and you'd need some creativity, which comes from truly understanding the math.
  14. Um this is the way the IB is graded. 42 marks for your six subjects (6*7), and 3 bonus marks for your EE and TOK. CAS is required, but does not count towards points.
  15. Pretty sure that that's related to the travelling salesman problem, which I'm fairly certain is of a sufficiently high level for HL math If you restrict yourself to available roads, there are a large number of possible paths, and many different ways to determine which is the most effective (e.g. brute-force, the most inefficient method).
