  1. The last one had the settings listed! Thank you so much! Here are the settings, in case anyone else is looking for them:
  2. Hello! I am having my Physics exam tomorrow and I am wondering which press-to-test mode settings IB requires to be restricted on the TI-nSpire CX. I can't seem to find it anywhere on Google =( Settings include: "Limit geometry functions" "Disable function and conic grab and move" ... "Disable log_b-x template and summation functions"... etc... Anyone who knows which ones I could check? Thank you!
  3. Title says it all. I am very confused, and I think I have gone through all the TOK resources I could find. If not I am wrong, I did ask my teacher about it, but quite honestly - I forgot what he said. Whatever he said, it was with some uncertainty. So now am I unsure. Most places I read that I am supposed to take the title - derive a few 'knowledge questions' from the title, and write arguments and counter-arguments for those questions. And you have all this stuff about AOK and WOK... I think I have understood that part too. Anyways, do I include, explicitly, the KQ in the essay? Should I stick to one, or write about all 2-3? Would I put them in the introduction, or on the top in their respective main paragraph? Appreciate any help!
  4. Not familiar with chemisitry, but I think you are doing something wrong. Percentage error is not something you calculate between two values. If you have a value for some data, lets say that 'something' is 1,2 meter, but with an uncertainty of 0,1 meter - it means that this 'something' can be 1,1-1,3 meter. The percentage uncertainty of this 'something' is (0,1/1,2)*100 = 8,3% (In graphs and tables, round it to one significant digit if you are not using the value for any more calculations). Gonna need some more detail to help you out.
  5. Okay, I found it! Listed in this document. http://mrsmithsphysics.weebly.com/uploads/1/2/1/5/12150755/1.2_errors_and_uncertainties_notes.pdf Apparently, one is suppsoed to do what I wrote in [1] - make the error bars from "corner to corner" of the error boxes.
  6. They don't care that much about formatting, as this guy above me says, but by having a nice and clear format then whoever reads your IA will take it more seriously, which might grant a 6 instead of a 5 in some categories. I dont have chemistry but in physics, there are certain very easy things that can get you a 6 in DCP. Label graphs with units, in both axis' and the title. define all variables early on, dependant, independent, (un)controlled. Include units and uncertainties in all data tables. Use error bars in excel and make max/min slope lines. As for 'mistakes' or poor data - don't worry. Just do what you can and be honest about it. Uncertainties is good - at least it makes your graphs look better (sometimes I would artificially increase the uncertainty because the error bars in the graph were more or less invisible). I used a "checklist" for all the criterias when I wrote my IAs. It was specifically for physics though - see if you find one for chemistry.
  7. Hello! I am working currently working on my extended essay in physics. There's one thing I am a little bit unsure of, and that is the use of error bars in the x-axis. Okay, so by having them in the y-axis, you can make max-min slope lines, which is great. So I am thinking, and I could think of these solutions: 1. Just put them in, then you have error bars in both the x-axis and the y-axis, then graph the max/min slope lines from wherever that the slopes are at their maximum/minimum - The max/min slopes would then look like this: Very bad sketch. Anyways, the maximum slope would go from the minimum y-value, but maximum x-value of point 1 to maximum y-value and minimum x-value of point 2. Opposite for minimum slope. This makes their gradient as high/low as possible within the bars. 2. Calculate how much difference the uncertainty in the x-values (using the gradient from the trend line) the uncertainty in the x-axis could possible make on the respective y-value plotted and then add this uncertainty to the error bars in the y-axis instead. 3. Dont know
  8. Most universities (at least in the US) seems like they prefer Math HL/Physics SL rather than Math SL/Physics HL. Both at HL is probably the best way to go if you are motivated. When I started at my school we had to take "placement tests" in order to see if they would approve us in HL sciences/math. I wanted to do physics and chemistry at HL - or at least one of them - so I took the test in both. I had never had physics before. Had very little in a subject that "mixed" all sciences (at least 5-6 diciplines, including things like geology) with a few classes every week for a few years but this didn't help. My test scores were too low, but the physics one was the closest. So I took an "L" and just went with Physics SL at the start. After a few weeks of catching the concepts noticably quick, doing well on the quizess we got, I just talked to my teacher about changing to HL. He was very supportive and sent an email to someone in the school administration who take care of subject changes. Boom, then I was in HL. I enjoyed the fact people in my HL class were not only much smarter, but also much more enthusiastic about the subject. Im in my senior year now, so I can see that the SL and HL classes start to digress more. HL is a bit harder, but shouldn't be any major problem if you are doing well in the other subjects and have some extra time to put into physics - that's at least what I do. As for you. You haven't even started the school year. "Is it too late to catch up"? The IB Physics curriculum starts with things like uncertainty and significant digits. Really easy stuff. It doesn't require any previous knowledge. In my class now we are doing nuclear physics. Most of my peers know half of the stuff from before, but I don't. Took me 2-3 hours of reading to catch up. No big problem. If you see yourself as motivated with decent study habits, ready to "nail" the IB diploma, then just go for it.
  9. Keep up with everything you do in class. Go through the book until you have the feeling "Okay, now I am ready for a test." - find some previous papers online. Do only the calculus ones. Once you do like 10 (gonna take you an hour or two), you will feel much more confident and you wont make silly mistakes.
  10. Getting a 4 at HL is definitely easier. And the additional concepts for HL isn't that hard in my opinion. Many of the concepts that are for both SL/HL is harder than the ones that are for HL alone.
  11. I believe Investment Banking is the most prestigious career. HOWEVER, I do not think it is a very good career. You have to work VERY hard, the culture is very competitive, the pay is not as good as it is commonly believed. It is basically a hierarchy there, and if you are able to advance to positions such as VP (will take you 5+ years), you will start making some decent money. The industry is in decline, so the people at the bottom (recent graduates) are the ones who have to suffer the most in terms of lower pay. Corporate Lawyer is probably also a very prestigious career, but can be hard to get into. You need very good "people skills", and you have to work your way up.
  12. The people complaining that it's too much maths (from my experience) are the ones that get a mediocre grade in math studies. If you do well in studies, or have SL/HL math, then it is probably easier for you to get a high grade in Economics HL rather than SL, due to paper 3. So the only reasons that you would take SL over HL is: * You already have 4 HLs (I have 4, and would have wanted another one but my school does not offer SL A-languages) * You can't stand mathematics. The mathematics in Economics HL is REALLY simple. It's very basic algebra with some formulas and some graphs for calculating things such as revenue and profit.
  13. So far Ive found two other schools in the US offering Norwegian A HL, and a few others in other places of the world. However, if it is true as Babydolleyes say, I will have a lot of schools to pick from. At one of the schools I found offering Norwegian A HL, the tuition is half of what it is here - and the facilities can't possibly be better. And well… I said my teachers were good. The only teacher I think is really good is my physics teacher - my Math and Econ teacher is above average, and the rest is just around what I guess is average. I think I just see my teachers as good because I came from a school with terrible teachers where everyone refused to work in class. Anyways, there is so many problems with the school I go to now, and even one of my teachers agreed to so and said that he would never send his son to ´this school´, not even if the tuition was half of what it is here. How should I proceed to potentially change school after the summer? I probably have some deadlines Id have to nail. Should I perhaps send an email to one of the schools and ask if it would be possible to go there as an IB senior?
  14. Hello! Im in my first year during my IB diploma right now, and I have been thinking about going to another IB school. The reason is that the school I am going to now is extremely commercial, where as we pay a lot while they put 1200 studeacents on a 25 acre campus (4 students in a 4*5 meter room), provide us with terrible budget food, and they underpay and exploit the teachers (we have very good teacher though), etc... One thing is that I have to continue with the same subjects, but there are still schools out there with the same subjects, so I guess it shouldnt be a problem (?) Anyone who tried this? Would appreciate any response! Edit: Also, is there any way I can search for IB schools offering specific subjects? (My concern is Norwegian A).
  15. History will definitly help you in Econ and also help you at the SAT History test if you are going to study in the US. The SAT II History test is the only social science subject test, and so, if you want to study Economics you should definitly take an SAT II in history (either one of them). The math is good to have in case you would like to study the hardcore economics related courses, such as econometrics. It is also very favored by admission. English B - I don't know how you master english, but as economics is a social science english is a big and vital part of it. Find out the difference between HL and SL English. Physics doesn't really help you that much expect for all of the reports and IAs you would have to write. The graphing part in physics and all the use and manipulation of formulas can also help you in studying econ. However, the difference between Physics SL and HL isn't that much in terms of how much it will hepl you in studying economics. Keep in mind that if you change your mind (like I did, but I am still in year 1 with the right subjects), physics HL is good for any science or engineering related major, including any medical degrees. To be fully honest, I would change any of them expect for math based on grades in the subject. If you know that you can get a higher grade by switching to SL then do it.
