  1. I didn't write my EE on CS, nor did I take it as a subject in IB, so take my words with a grain of salt. First of all, your topic is too broad, because it's basically about the entire of the OCR technology. Also, the difficulty depends on what learning algorithm you are choosing to focus on. Some learning algorithms are nuanced, but difficult to understand. Some are naive, but very easy to implement. Last year, I took the machine learning course on Coursera, taught by professor Andrew Ng, and there we got to implement a little program to recognize handwritten digits. From what I remember, it w
  2. Your courses look quite alright for computer science. In fact I've just finished my bachelor in computer science myself, and your course selection is very much similar to mine. Math HL is a must for CS, there is no way around that. As for physics HL, it's not really necessary. I mean even if you go into things like 3D programming or hardware (where knowledge in kinematics, circuitry, and quantum mechanics will prove useful), physics SL is usually enough. However, I've heard that many Canadian universities require CS students to have at least one science at HL. So I'd recommend you to keep phys
  3. Agreed with @SC2Player, the study doesn't exist! I've searched everywhere on google as well as my university library, and nothing came up. Most results on google are from some IB websites or blogs which (I suspect) got their information from some secondary resources. I believe this was originally started from the mis-citation in the IB psychology course companion by Crane and Hannibal that was published a couple of years ago. The general rule of thumb is don't use any study which you can't find the original published paper (or at least the abstract of the paper).
  4. Like @alexalexalex said, of course it depends on your which university/program you have applied to. You can generally estimate your chance by doing the following: Convert your predicted IB score to the Swedish score according to the table HERE. Add some bonus points according to this PAGE. Remember that you can get maximum 2.5 points extra. Go HERE to see which selection group you belong to. Most likely, you will be in the BI group. Go to http://statistik.uhr.se/ to check the points required as well as other statistics for the program that you've applied to (maybe
  5. For statistics, you can use R, which is a powerful open-source scripting language for working with statistics. Since it's open-source, many people use it, and thus you will get lots of helps online. Remember to download both R and R-studio. If you are absolute beginner in scripting languages, I would recommend looking at this link: https://support.rstudio.com/hc/en-us/articles/201141096-Getting-Started-with-R Otherwise, Excel is another great program for statistics and graphing in general.
  6. Haha lol, the rope story sounds quite silly, I wonder if that was true. In any case, IBO doesn't give specific rules regarding fire alarms during the exams. So it's up to the your coordinator to decide what the students must do. By the way, on the file uploaded by @kw0573 (see here https://www.ibsurvival.com/files/file/3500-the-conduct-of-ibdp-examinations/), it says the following:
  7. Maybe it was just me, but I didn't want to use the formulae booklet in physics at all (perhaps in maths, but not in physics). I preferred to actually know all the formulae by heart, or at least be able to derive them on the spot. In EM induction (and also, alternating current), there are many formulae for different things, and these formulae are all very much similar to each other. That's why I got very confused, especially with sine and cosine, like when to use which? But after learning about differentiation and integration, these things were much easier to understand. For example, for the Fa
  8. I was in HL physics, and thought that gravitation was extremely difficult to understand. But circular motion was like a piece of cake though. Another topic that I found difficult was electricity and magnetism, like electromagnetic induction for instance. I only fully understood that stuff once I did calculus in maths. Thermodynamics was difficult too, especially the first law, but after a while, things got easier. As for SL, I've heard from my friends that gravitation and waves were pretty difficult for them.
  9. 17. Be nice to your teachers, so that you can ask to extend the deadline whenever you want . For example, whenever you talk to your teachers, try to discuss about some intellectual things to make them think that you are smart and that you are on top of everything study-related. That way, it will be easier for you to persuade them to extend the deadlines for you. Generally, there's no recipe for how to be nice to your teachers. But maybe just try to ask them about their personal lives (as if you really care haha). This strategy actually worked very well for me, because it always distracted my t
  10. Where did you hear that there will be no timezones for 2017? I don't really know exactly how this timezones business works, but as far as I'm aware, the only exams that didn't have timezones in May 2016 were the science ones (e.g. physics, chem, bio). Other exams, like maths, still had both of the timezones. My speculation is that they were just testing it on the science because it was the first year for the new syllabus. Who knows, maybe they will bring back the 2 timezones this year? In any case, don't worry about how IBO does things. Just don't try to cheat! haha
  11. @TheNintendoChip Your solution is correct, but it seems unnecessarily complicated. I found another solution that doesn't require us to use geometric series (solution attached as picture below). @tutorinseoul Correct me if I'm wrong, but are you sure that this is the type of problem that is likely to be in an IB exam? To me, this seems more like an Olympiad riddle rather than a problem for math SL.
  12. Ask you school and see if they can get you the digital copy of the worked solutions (link: https://www.haesemathematics.com.au/books/mathematics-sl-worked-solutions-3rd-edition). Here is another link (http://www.slader.com/textbook/9781921972089-mathematics-for-the-international-student-mathematics-sl-third-edition/). I don't think it has all the exercises, but you can find many of them there. Otherwise, just try to look around on google, I'm sure you'll be able to find the full version.
  13. Like what Gaby said, you don't really need knowledge from those subjects to study in the field of computer science. But you still should check directly against the universities that you want to go to. I know that most universities in Canada require you to have both physics and chemistry to be admitted to their CS programs. Personally, I think taking chemistry or biology would be a bit more useful than psychology, because it's possible that they might get you interested in the field of scientific computing. For example, bioinformatics is about developing new technologies to be applied to the fi

  15. This varies year after year and it depends on when the IBO wants to release the papers. But it usually takes 4-5 months after the exam for the papers to be available on IBO store. And about 7-8 months to see them somewhere on the internet (but mind you, it's incredibly hard to find).
