    Help with HL Math IA (Calculus)

    I think the wikipedia page is ok. Just beware of different convention in spherical coordinates whether its math or physics. I think it would be good to first do everything in Cartesian, then if/when you have extra time play around with other coordinate systems.

    Maths HL Intro to Calculus Questions

    @literaturegirl Are you sure that (1, 2) is on the graph of f(x) = x^2 - 5?

    CHEM IA PLS HELP BEFORE ITS TOO LATE!!!

    This is a somewhat bad chemistry topic, because you need a relatively strong grasp of physics (eg free body diagram on the marble and drag equation, consider the buoyant force, likely then use net force to find acceleration and time). Another thing is that any data you compare to are also empirically-found, rather than based on some theoretical model (ie very hard to extrapolate, can only interpolate). It does involve some thermodynamics (thermal chemistry) but it wouldn't be a strong chemistry topic, This would be an ok to good physics IA topic, though.

    Stolen idea

    It is also possible to find an academic source that says what your internet source says and cite that instead.
  5. Yeah so briefly explain what prompted you to change topic and how you came up with the new topic.
  6. Because the reflection determines your engagement grade, you should write it on your current topic, while mentioning how the topic change affected your research process. As the reflection is graded by the same examiner who is marking the EE, you should write it in Chinese.

    Some users have reported that this file is not accessible. You should be able to access the .pdf if you are a VIP.

    Help with Physics IA topics!!! Springs

    Both topics are ok. You could also investigate spring in series vs in parallel. The relationships are well known for both topics, which makes the experiment easy and almost trivial. You can get a good grade but you should look for a better topic if you want to get near perfect.

    Which maths should I take?

    I would like to point out IB is introducing Analysis/Approach (functions and calculus focused) and Applications/Interpretations (modelling and stats focused) courses to replace current studies, SL, HL and it will remove Further Math. I would probably suggest Analysis/Approach SL or Applications/Interpretations HL. Application/Interpretations SL is essentially Studies and is insufficient to prepare for pre-med, and at the other hand Analysis/Approach HL is entirely unnecessary.

    Surviving a grade 1 in exams?

    If you are struggling in any course or assessment, please be sure to communicate with your instructors so you get the help you need to pass IB.

    Surviving a grade 1 in exams?

    So the grades in IB works by taking a weighted average. This is a gross simplification, but if you get 3/20 on the IA and 15% on each of the final papers, that's a 2 and a conditional pass (if other grades are good enough). 1 is a definite fail. 2 is pass if a bunch of other conditions are met. I really hope that if you study hard enough, you can score 20+% on the papers which will not be automatic fails.

    Surviving a grade 1 in exams?

    A level 1 is 15% overall average. Are you absolutely sure that there's no way you can get 15% by your May 2019 exams?

    Mistake in EE

    I stand by what I said. I deleted it because I thought I should have give others an opportunity to answer. Anyways, it does sound like a large mistake but you should still pass.

    Help with HL Math IA (Calculus)

    The HL "Use of math" criterion describes sophistication as follows: If there is no sophistication, the highest you can get is 3/6 in use of math. A well-annotated derivation of regression formula would have been an excellent and foolproof way to connect calculus to stat. Data interpretation may make it difficult in scoring well in communication and personal engagement.
