  1. http://www.amazon.co.uk/The-Ultimate-BMAT-Guide-Techniques/dp/0993231101. I know that no one is following this thread. However, in the future if any of you are considering taking the BMAT, use the linked book. It is excellent. I'm sure it will raise your score dramatically if you follow it well.
  2. This problem can be re-formulated like this: Find 2 integers x and y, such that they satisfy: If you have done the Discrete Maths HL option, then you would realize that it's possible to apply the Euclidean Algorithm backwards in order to solve this problem. So let's begin! First, we apply the Euclidean Algorithm using the 2 integers 22133 and 24900 as follows: Line 1: Line 2: Line 3: Line 4: For line 1, we call 24900 the dividend, 22133 the divisor, 1 the quotient, and 2767 the remainder; Then the Euclidean Algorithm simply tells us to make the divisor of line 1 to become the dividend of line 2, and to make the remainder of line 1 to become the divisor of line 2. Then we'll have to find the quotient and the remainder for line 2. The same process is repeated for line 3 & 4. Euclidean algorithm can only be stopped if you get 1 as the remainder (which is exactly what it is for line 4). I'll leave you there you understand why that must be the case. Now, let's apply the Euclidean Algorithm backwards. From line 4, we have: Our job now is to re write this equation above using only 24900, 22133, and 2 other integers (eventually for x & y) based on the information in line 1, 2, and 3. This might look complicated, but just follow the common sense: (from line 4) (from line 2 & 3) (from line 1 & 2) (from line 1) Clearly, from the result above, we know that and Check that using your calculator, and you'll see the magic result. Feel free to ask if you have further questions! Jesus christ man. The time you have as a post IB university student!
  3. Did anyone do question 7 on section B Chem HL ? Seems as If no one did. (TZ2)
  4. Here's French B: French B Nov2014 Report.pdf I can't however find Spanish B report for November 2014 though. Perhaps it hasn't even been published by the IBO. So here's the May 2014 version instead (in case you haven't seen it): Spanish B May2014 Report.pdf You must be quite talented with Google Vioh because I am unable to find a single one of those subject reports!!
  5. Oh I meant for November 2014 but thanks anyways.
  6. Hi, do any of you know the grade boundaries for paper 1 & 2 Chemistry HL NOV 2014 ? Thanks.
  7. I love this paragraph of your post the most, because I hold exactly the same point of view. Getting a tutor is a lazy alternative in my opinion, because it often discourages people's independent-thinking ability. Learning stuff by ourselves is not only fun, but also very rewarding. This is because thinking independently can help increase our curiosity within the subject which will consequently encourage us to look for a much more nuanced understanding of the subject. Generally, I think it's better to avoid having a tutor. If you find a subject hard, then "fill your heart with love is enough!!!" (quote from Richard Feynman) This would be true in an ideal world, however sometimes students are "behind" due to a lack of previous education, through sheer laziness or some other reason. A tutor allows them to catch up in a fairly short amount of time. For example, I personally struggled with Math early on in the IB, however after getting a tutor, I currently have a strong seven in Math. Personally, I think it is very ignorant to describe the use of a tutor as a "lazy alternative"
  8. Thank you! Just the clarification I needed.
  9. Hello everyone, I am currently doing my extended essay in philosophy on "capital punishment" and i am struggling with whether i should focus entirely on Kantian ethics in terms of "punishment" or rather several ethical theories such as utilitarianism etc. Does it really matter in terms of the grading criteria ? Thanks in advance for your responses.
