  1. remember that 1/x = x^-1. So 1/x^(8/5) would be equal to x^(-8/5). You can then use the power rule to differentiate like normal -8/5x^((-8/5) - 1) = (-8/5)x^(-13/5) If you want to take the negative out of the exponent: -8/(5x^13/5) (It looks clearer handwritten).
  2. I don't mean to scare you, but pretty much all chem IAs should have an independent and dependent variable. In other words, the title should be something like "how does x affect y?". There is only one variable in your title, the mass percentage of calcium carbonate. This would make you fall short for exploration, analysis, and maybe evaluation criteria. I don't know what kind of data you collected or what method you used to find the percentage of calcium carbonate, so you could potentially use some of your data to serve as your independent variable then restructure the IA around that. For example, pH of surrounding water could be your independent variable (idk if this is a relevant variable since I don't know anything about the stone, I'm just making this up) and mass percentage of CaCO3 could be your dependent variable. Good luck
  3. From what I've heard as long as you have made it clear which question you have answered you will be fine. Your exams are marked by actual humans, not robots. You should contact your IB coordinator ASAP though just in case.
  4. I would recommend taking a look at basic vocabulary, learning conjugations for common verbs (verbs ending in -er, -ir, -re, and some common irregulars such as avoir, etre, faire, pouvoir, etc.), other basic grammar, etc. if you don't already know those. Make sure you are applying what you learn by reading news, books, magazines, and practising speaking and writing in French. Pay close attention to various francophone cultures (there are A LOT) as you will be asked to make connections to them. There is no way to study for specific evaluations so the only real way to get better is to keep practising. Also, most people taking French B SL are not fluent, so you won't be at any disadvantage. But I heard from them that it is indeed difficult. Good luck
  5. You will most likely have provincial exams like normal throughout grade 11 (and grade 12), though maybe not all of them. This depends from school to school, sometimes even teacher to teacher. Some schools may also do their IB SL exams at the end of year 1, and the HLs at the end of year 2. You should check with your school on this because most schools do all IB exams at the end of year 2.
  6. Structure depends a little bit on the subject you're taking, but in most cases, you should define key terms then talk about the arguments and counter arguments. The "thesis" is usually really short. Definitely definitely definitely DEFINITELY consider both sides of an argument, having a balanced argument is in the rubric of almost every IB subject that includes short answer. Don't worry about "weakening" your point by considering both sides. Having a balanced argument is more important than trying to prove a point.
  7. Unlike MYP, pre-IB is not an official part of the IB. All of your requirements are local requirements and they differ from region to region, so you would have to ask your school about examinations, requirements, etc.. It is entirely possible to teach yourself a subject. There are tons of articles, videos, practice problems, etc. that are just a Google search away. See if you can get your hands on a textbook since the bulk of your lessons probably come from there. It just takes a little bit of dedication and discipline, don't let one teacher ruin your whole career. Good luck
  8. In my experience, this is not true. I have heard plenty of explanations that it increases grade boundaries and can therefore make the course harder for non-native speakers. However, I don't think the IB has any written rules against enrolling in language B/ab initio. Just by looking on the internet I've heard of people enrolling in language B/ab initio in a language they're fluent in to get easy marks. Even in my own school (keep in mind, a bilingual country) where a lot of people have done bilingual programs since the beginning of elementary school do language B for their second language.I think these rules are probably for individual schools and not from IB. So, @UnknownStudent, I don't think IB has anything against enrolling in language B but you'd have to obey your school's rules anyway. If you aren't able to convince your school to let your enroll in lang B French your only option would unfortunately be ab initio or transferring to another school that might let you do it.
  9. I can't remember my exact question and I don't feel like digging it up lol but I think was looking at whether a company's practices were ethical. I used some legal documents and some company policies. I think I used it to see how its official practices compared against the law. Everything else I did was pretty ugly, and I admit, I did only OK on this IA, so I know a bit on what NOT to do. They still haunt me to this day lol. My question was shallow despite exploring the same topic as you, and I used some very weak sources to try and show the general population's opinion (not the policies or legal stuff), when I should have looked at a bigger picture instead of a couple of biased sources. I can't remember much else off the top of my head but I remember using weak sources made me lose a lot of marks, and being a bit overdependent on sources made me lose analysis marks. Instead of balancing my points I turned completely towards my crappy sources as a measure of how ethical a company's practices were. So legal sources can potentially be a good measure of ethics (although you should try not to assume that legal=ethical), as well as company policies or any hard proof of what companies do and try to achieve (instead of looking at a single promotion, ad, etc.). Probably the biggest challenge will be an effective way of measuring a region's moral view on topics.
  10. I did something similar for my business IA, and my teacher approved of it. I think your question is perfectly valid and has a lot of potential, but there are some things I would watch out for. 1) Personal bias. I can see why this is unsettling you a bit since the EE guide says it should be unbiased, and you really need to watch out for this when you do your essay. Try to take into consideration other people's opinions rather than your own since ethics is defined as a moral code within a culture, region, etc. To try and minimize the impact of this you need to have balanced arguments (discuss ideas for and against your point). 2) Bias from your sources. Try and pick secondary sources that have very little bias and use facts to support their claims. I use https://mediabiasfactcheck.com/ to verify what type of bias my sources use. In most cases you'd choose sources that are left-centre, least biased, right-centre, and pro-science. However since you're dealing with a topic that includes a lot of biases, I would just use least biased and pro-science sources (sometimes the slightly biased sources if they cite sources and don't use loaded language). Good luck with your EE
  11. I think it depends on your subject choices. For me personally it was only slightly harder than grade 10 pre-IB, and the only really difficult subjects I had throughout the year were math HL (which I dropped because of mediocre grades) and English Lang and Lit (I just straight up suck at language). You will definitely have to put in some effort if you want good grades though. It's not like previous years where some subjects you can sit by with no work and end up with a 90+ average. The most stressful parts of grade 11 for me were the assignments with long deadlines (extended essay, IAs, etc.) since you need to manage your time effectively and try not to convince yourself that you have "plenty of time" since your deadlines can often be months away. I think what matters most are your study habits. If you develop good study habits you will be fine no matter how tough your subject selection is.
  12. In your applications you should mention your struggles and how you overcame or coped with them. Do not overlook your financial struggles in your applications just because they are a problem that doesn't originate from your academic life. If I remember correctly, there was someone (can't remember their name) who made it into Harvard with a very low GPA (<2 I think) because they had to support their family and had to prioritize their 2 jobs over school. Their struggles showed that they were resilient, determined, prioritized appropriate tasks, and could handle the university workload. I don't know the specifics of your situation but just from reading this I can tell that you are spending your very limited resources towards your extra curriculars/academics, which shows your determination to go to uni. Good luck applying, and good luck with your situation
  13. I know a few people who ran a YouTube channel for their CAS project. Their channel had lessons, exam tips, and maybe even a couple songs for one subject (can't remember which one though). However, it always depends whether your IB coordinator approves of the idea or not.
  14. The only business related extra curricular that I know of is DECA, and it's worth it. It counts for CAS and looks great on resumes and university applications. https://en.wikipedia.org/wiki/DECA_(organization)
  15. Your 40 volunteer hours will not count towards CAS. Your school will push you finish your 40 volunteer hours in grade 9 and 10 because of this reason, they are separate requirements. You must finish your OSSD hours before you start getting CAS hours. It is not mandatory to finish your OSSD hours by the end of grade 10, but I don't recommend putting it off since then you would have to do both CAS and OSSD hours in grade 11 and 12. You really don't need to worry about CAS at this point since in most places you would have to wait until the beginning of grade 11 (September for you) to even start. Just focus on your OSSD hours and you will be all set for now.
