    Can a retake be cnacelled?

    Hey glad to hear it's working out. I think the subject fee can be refunded. I am not sure. I thought Jan 15 is deadline for NEW STUDENTS not retake students. Again, my info is outdated by a few years but that's the info i have. EDIT: I say this because Jan 29 is deadline for RETAKE students to register but Jan 15 is for new students only.

    Math Analysis or Application

    From my impression, A/A is the current SL/HL and A/I is the current studies with some additional stats and technology. I guess by that logic, Applications/Interpretations would be easier but not free 7 by any means.
  3. For class of 2019 and later
  4. For examinations on and after May 2020.

    SL Maths IA Ideas

    Hi Johs20! We can help you carve out a clearer path to your topic, given details of concepts and problems that you want explore.

    I need serious help!!! :O

    I think there are two things you can do immediately: setting goals for short-term and removing distractions. 28/45 is a point on the map, but you need to identify the route. Focus on the task at hand. Confused in math class? A reasonable goal would be to ask teacher after class/school/during lunch on what you were confused about that day. Paper due in 5 days? In the next 2 hours ,find/read through all the research you will need. Think of work as water corroding a rock: it takes persistence and time. Most importantly, it is about turning hard, general goals into easy, specific tasks. Work without use of technology, or restrict use of technology. As weird as it might sound, it is physically possible to write an essay without using the computer. It is physically possible to do homework using just your notes, the textbook, and a calculator. Turn off your phone and computer when doing work. I would recommend starting with 20 minutes of no-distraction work period, following by a 5-minute break. Best of luck!
  7. Unless you are at the top boundary for a 2 in the oral and written assignment, it is not possible to get a 5. A 4 is still up for grabs though.
  8. You should write the EE in your best subject. Universities do not care what EE subject you choose.

    Regular Academic Math vs Accelerated Math

    There is no longer any HL Further Math, or even HL Math. The new courses are HL/SL Applications and Interpretations and HL/SL Analysis and Approaches. A/I is stats focused and A/A is functions/calculus focused. There is significant modelling in both, and both courses share about 25% of the same content. If you are thinking of going into engineering, sciences, economics, computer science, then you probably need A/A; otherwise you can take either one. Unless after high school you plan to do something that does not require advanced math at all, eg literature, it's best to take the 1DE so you have options to take either math courses. 1DE keeps more options available. If you apply within Ontario for university, they need at least one of the 4U courses (advanced functions, prob/stats, vector/calculus). While 1D certainly still progresses towards these classes, taking an accelerated 1DE will make a smoother transition to the harder math classes in future years. It has typically been the case that SL is easier than 3U/4U courses and HL is much harder.

    Math IA guidance needed!!!!

    I think you should figure out that yourself, and I should say that if you have the actual cup, it's not difficult at all. You can also try to find a way to do this without calculus, and compare your answers. The truth is that the most complicated method is not always the best. If you have the cup, there are at least 2 non-calculus ways to do this. EDIT: Other than the scaling issue, there is an inherent problem/error in the way you tried to fit the curves to the cup which is that a cup does not (and should not) look like the curves. In fact you are making the volume harder to calculate than what it should be. Alright that's enough critique/hints from me, wish you the best!

    Math IA guidance needed!!!!

    Well right now you are finding the volume of a cup that is 4 cm in diameter at the open end, and about 8-8.5 cm tall, which is just honestly a tiny cup and 70 mL is not all that unreasonable.

    Can a retake be cnacelled?

    Hi The data I have is 3 years old. It says you can still withdraw one or all of the subjects if the process is completed before May 1 the session of the May exams. by contacting [email protected] Contact your coordinator first and if that were to not work out then contact IBO directly.

    Help with my EE Topic?

    To convince your teacher, you should clearly identify ToK concepts that you will be exploring from his music.
  14. kw0573


    It's harder than it sounds, but a D in ToK starts at 4/30. You do need to submit both a presentation and an essay to pass ToK.
  15. That would depend on your preference, to choose between an AoK and authority or a WoK and AoK (among many other possibilites).
  16. kw0573


    In general, you should avoid phrasing in a way that can be interpreted as Devil's advocate. It appears that you are suggesting unethical behaviors can be validated, which may not be what you intended. It's just an observation I am not sure exactly how to fix it. Also keep in mind that whenever you discuss ethics, you should focus on how ethical criteria are established, not to use specific ethical guidelines to evaluate something. It is exactly the same reason you would not solve math problems or pull out a supply and demand curve when talking about their respective AoKs. I recognize that I have only point out potential issues and did not offer any solution, but hope that helps!
  17. I like the first one (art censorship) the most. It clearly identifies an AoK and a relevant ToK term (authority). To identify both language (WoK) and art (AoK), you can say something like "To what extent is language censorship in art justified?". I would not recommend KQs that suggest too much of a bias (offensive language as opposed to simply language) or too little/broad (what is relationship between x and y).

    Entry requirements prior to IB predicted score

    You should ask your school for predicted grades in EE/ToK.

    Math IA topic help!

    You should pick a math topic first then pick the application. It sounds like you are picking golden ratio which is most likely way below SL standards. I would suggest that you pick another math concept to focus on.
  20. kw0573


    Yes, I have come across many good topics, but I don't recall ever suggesting one. Most of the time I just gave feedback on the topic they came up with. I honestly don't know how to do chords without doing some sort of fourier transform, which is just too cumbersome to learn on your own (calculus beyond HL). I think you should look for topics regarding math you want to discuss, such as trig, instead of looking for ones related to a particular field, such as architecture

    Reverse Chain Rule Help

    This so-called reverse chain rule is u-substitution. it's just written differently. Also I'm pretty sure you have seen results based on this rule, even if it weren't introduced as such. Quick remark about notation, f'(x) is the derivative of f(x) and so f'(g(x)) is (f' º g) (x). Say f(x) = x³, f'(x) = 3x², g(x) = 5x - 7 and g'(x) = 5. From here, we see f'(g(x)) g'(x) = 3(5x - 7)² × 5. So ∫15(5x - 7)² dx = (5x - 7)³ + c. Applying the reverse chain rule might become so automatic in integration of polynomials that sometimes you forgot you are applying a rule. Maybe you were taught that if a factor is inside the base, divide by the factor when taking the integral. But this comes from this very rule of reverse chain rule/u substitution. Take another example, ∫e^(2x + 1) dx. f(x) = f'(x) = e^x. g(x) = 2x + 1; g'(x) = 2. Then we know that ∫2 * e^(2x + 1) dx = e^(2x + 1) + c, so ∫e^(2x + 1) dx = 1/2 * e^(2x + 1) + c. Final example, ∫x(x² + 3)^4 dx = (1/10) * (x² + 3)^5 + c because ∫5(x² + 3)^4 * (2x) dx = (x² + 3)^5 + c. Where f(x) = x^5, f'(x) = 5x^4, g(x) = x² + 3, and g'(x) = 2x.

    It's better to do a topic you understand at least 80-90% then one that you understand 30-40% and have to learn the rest. What math concepts that you exploring? I like the mathematical relations discussed by this youtuber. https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw. The content is accessible to students with ok to good foundations in pre-calc and draws relationships from many topics, which IB is looking for.
  23. kw0573


    What topic did you choose and how are trying to explore it. As I understand, you have already submitted a potential topic to your teacher?

    TOK essay KQ help

    I like the first one. The precise wording you can always change as you write and you can change the focus slightly.
