  1. Isn't it more like new boundaries are to be set for first examinations (as Sciences 2016) and boundaries that are already set, remain set? This is no news.
  2. I still don't get it, my head just doesn't seem to work in this specific ay. I really need no explanation of how to do it, as I've read uncountable times the rationale. i just need to know, in my working, how am I supposed to go about? I plug the k+1 in every n. Do I expand? Do I move things around? What's the final objective appearance-wise?
  3. CALCULUS I am really a calculus enthusiast and spent two hours every day the last 1.5 years doing calculus, so I'm as crazy as to claim being able to score full marks. That would really impress the examiners, right?
  4. I think I failed this paper. I easily lost the whole 60 points from section B. I am good at maths, but the single two topics I overlooked had to come in section b, complex numbers (SPECIALLY de moivre's theorem and planes), and question 13 could have saved me, since Calculus is my thing, yet I left the question unanswered because I didn't see it (screw me right?). I freaked out so much at qs 11 and 12 that I didn't check the last page. I don't know how that was even possible. I'm looking at some 35/120 :'(
  5. I really need to ace these two papers, as my score will otherwise be very badly affected by this year's physics strangely hard papers. I'be never been specially clever or interested in this subject. However, my teacher many times qualified my answers and strategy choice as "insightful". I don't think she really has that much experience and my school has never got a single 7 since the subject started to be taught. Yet, my IA got 22 marks according to my teacher's marking, and since it was not chosen for moderation, I'd say it's going to be pretty much the same. I've realized from past papers that the finance questions really make a difference in both papers, as you can't really invent the answers. This is no problem for me, I guess, since I took Math HL and Physics. But the other questions, where you are said to have to come a up with a very good real-life business strategy is what freaks me out. I usually just write very crazy ideas and my teacher likes them, but I only do that so she likes them and says good things about my work, but I'm not convinced that's how the subject works, right? Also, our teaching was very deficient. We only got Power Point presentations EVERY single class, which most often were actual copy-paste from the book. We never got to randomly analyze a business strategy, or read the newspapers, or do a debate or stuff that I hear people were doing on a constant basis in other schools. So, I really feel like I just rot memorized lots of names but really know nothing about the ins of business theory and stufff. I need a 7.
  6. Hi, Thanks a lot! I kind of don't habe time to care about the philosophy behind it. It's mostly the hands on thing that I want to find about. Once you've plugged (k+1) in for every n, what are you supposed to do?
  7. Please. I have read this chapter the entire day and I am about to give up. All I see is they doing weird crap. So step (1) is plugging in 1 for any n. So far so goo. Step (2a) is plugging k for any n. No problem. Step (2b) is plugging in (k+1) for any n. And theeeeeeeen whaaaaaat??? What have we freaking achieved with this other than getting a mess of an expression? How is that of any meaning? I don't even understand the algebra they with the plugins and then out of the blue they claim it's all nice and demonstrated. HOW COME?
  8. I'm very very curious that I made a poll to see who chose what, because apparently in my class, everyone chose Q1.
  9. I felt overconfident about today's test, but in the end I think I will not do so well in P1 because the bulk of the exam were topics I overlooked / had no time to study in detail. I am looking at some 35/120 marks, which is markband 3. My exploration falls within mark 6. I am very good in calculus and I have one week to study very well so I may think about a 7. P2, should bad luck not befall be again with weird topics, let's say a 6. Also, in these conditions, would a 7 in P2 be of particular hope? Is a 6 or at least a 5 still within my horizon?
  10. Like if the question says discuss the efects of such thing on such 1 and such 2, does it make for a good essay to have an introduction, where you for example, make a statement about the present, and then expose different instances in reverse chronological time, and comment the indovidual instances signifiancw and then you wrap it all up with a general statement that says something like, therefore because of these reasons, we understand the presnt as the efect of all those suches. The other question type that gets me anxious is the "to what extent" type. Like, for this I wrote only like very subversive stuff, kind of stream of consciousness because I had 20 minutes left, and so I only very straightforward said yes, yes, yes in different ways and there it was. No no's. Does this combination a count for something reasonably good, or should I start lowering my expectations?
  11. I hope this doesn't account for a violation of the 24 hr rule. I'm not even referring to this examination in particular. I just mean P2 in general. Is it hard to attain 25 marks? Would two slightly below average tests score enough? Like, without contrasting lots of view, using just about enough examples, and being a little vague and disorganized here and there?
  12. Yah, I did the exact same. Yeah, sth like that mee to. That's because you clearly converted to m/s, right? And the one of the binding energy in P2 i got 80 MeV. I got the defect in each side of the equation and then the change in mass.
  13. I kept asking myself why I didn't know anything. Like really, what was wrong with me? If perhaps P1 was reasonable if you thought ever question very well, and deduced some nitty-gritty stuff here and there, expecting you to do that in 45 minutes is ludicrous. P2 was bad. Like I felt you could throw at me anything from topic 7 (particles) and I would solve it, and then the reaction showed you more binding energy, yet a smaller mass? Like TF was that? The waves question was quite ok too. You could deduce the period easily by looking at the graph. It was displaced 3/4 of a period to the right, so if you got that time you simply had to multiply it by 3/4 and you got the period and thus the velocity, RIGHT? The sun albedo questions were perhaps the only questions that were entirely appropriate for the paper. In fact, they were literally the examples that you find in the 6th edition Tsokos. If I just had had the time to study everything, but my teacher barely covered up to chapter 5.1 of the syllabus, and left us on our own 100% to do everything else. Everything else didn't make justice to what I studied, specially the Ice-spring question was obscene. I ANSWERED 19 marks, and assuming that hals of that is correct, we are looking at some 10/50.
  14. Math HL is quite ok, if you like them anyway, and if you really have the gut to stomach that much knowledge.
  15. I ABSOLUTELY need a 7 in Maths HL to enter University, and I feel quite capable and within the 7 markbands as regards the papers, without boasting. I've literally sit for at least 3 hours every single day during the last year to do exercises, so I know I will get the 7 in the tests. However, for the IA I feel like it's a completely different story. I had to do it basically overnight. I was sleep-deprived. Did pretty much all my IAs that month, and on top of that I decided to do a very unusual type of work. It was about infinity, randomness language and π. In retrospective, I feel like I was perhaps too bold in my intention, because I really craved that 7. I didn't include a lot of numbers or symbols, but the mathematics were there anyway. Suffiicient I guess. But I'm conscious that I digressed too much the nature of the task trying to cover too many topics. Can you possibly still get a seven if you IA score falls within the 5 or 6 markbands, but you do excellently in the three papers?
