    6 Higher Levels?

    Now why would anyone do that to themselves?

    IB score

    The key is to work consistently, not necessarily hard. If you put up a plan to maybe work 3 hours a day after school (and I mean a full 3 hours without any procrastination) and then maybe 6 hours on the weekends, you will have plenty of time to relax, sleep and a little time for social activities (on the weekends). Most probably, you will end up with 45/45 on your diploma. Unfortunately, it is impossible to avoid procrastination, but the goal should always be to procrastinate as little as possible. Also if you sometimes feel like you have a lot of work to do, then do it straight away, but don't let it affect your sleeping schedule. I found sleep to be extremely important during my 2 years, so no matter what you should prioritize 8 hours of sleep consistently every night. One more thing, in IB1 I know that it seems like you don't have much to do, but in reality this year is where you could get the most work done. Why, you ask? Because there are relatively less assignments to be handed in such as EE, TOK essay, IA's etc... The reason why most people struggle in the IB is that they don't work consistent enough in IB1. So you want to make sure that you definitely do that. Trust me I have been through the two years and I ended up feeling I could have done a lot better if I worked hard enough in IB1. To answer your first question though: The IB is not hard, it is the simplest thing in the world. The only ones who make it hard are ourselves.

    How much did you study?

    In my last two weeks before the exam I reckon I studied for about 6 hours every day, but I studied a lot more for Physics than any other subject though... Now I only have Chemistry left... Ah feels good man!
  4. This guy has listed 99 resources to help for the IB economics programme: http://www.timwoods.org/2012/02/26/the-99-best-economics-resources/ Check it out... His tips on how to structure economics essays helped me out a great deal Best of luck!

    Elementary concepts: Bonding + Periodicity +Stoichio

    Hmmm... The last calculation he did uses the same method as mine actually, I just forgot to make KCl 20 % of the whole solution. Hence the 0.8 number for H20 as there should be 80 % of water in solution. Also, when the task ask for 20 % (not stating wheather it should be mole percentage or mass percentage) im pretty sure we should calculate in mole percentage. I might be wrong though...

    1) I looked up the answer for you Vapour pressure is actually not the pressure exerted by vapour on its liquid molecules. Vapour pressure is actually the upward pressure of the vapour against the atmosphere in an open system (I didn't know this either ). So in order for the liquid to boil, the pressure against the atmosphere must be equal to the pressure that the atmosphere exerts on the system (i.e external pressure). Interesting question as I didn't think about this before. 2) Well I would have gone about it in this way: - Find the amount of KCL in moles: g/M=n => 45/74= 0.61 moles - How many moles of water do we need for 0.61 to exist as 20% of the solution: 0.61/0.20 = 3.05 moles water - How many ml of water is that? First convert moles into grams then grams into ml. We know that density of water 1 g /cm^3, and 1cm^3 = 1 ml: 3.05*18 = 54.9 grams of water which is 54.9 ml Do you have the correct answer somewhere? I'm only 90 % sure that this is correct. It's at least the way I would try to solve this problem. HI! Thanks for taking the time to solve this it's killing me! Sadly the website provides only the questions Can someone else please confirm the validity of this answer? What formula/logic is it exactly that you've used for this step, I'm not familiar with it and I've looked up the percent concentration formula but that only deals with masses, step: How many moles of water do we need for 0.61 to exist as 20% of the solution: 0.61/0.20 = 3.05 moles water You need a 20 % solution right? Which in an aqueous solution (any substance mixed with water) means that the substance must exist as 20 % of the whole solution. In this case KCL must exist as 20 % of the whole solution. Hence, we have to calculate what 3.05 moles is 20 % off to find the total moles of water present. So I used this formula: moles of KCL/moles of water = 0.20, since we know the moles of KCL in this case we can calculate the moles of water to make a 20 % solution.
  7. Try to think constructively. Don't peg yourself down by stressing too much and find ways to think of the exams as just another mock. For me it helps to count the the topics I have under control in every subject while still keeping the stuff I don't know so well in the back of my mind. Also, do a lot of past papers! In every subject, simulate the situation of a real exam as it will help you cover everything you don't know so well while calming your nerves before the exam. One more thing! Think of every subject as "easy"... and that if you do the right things this last weeks you will achieve your goals. That way you will not feel that you are hopeless. From what you say about your mocks, it seems like you have a good chance of getting 38. I found that setting up specific realistic goals in each subject helped me tremendously. Before I only thought about getting 7's in every subject, but if the pressure was just too much. So I thought to myself that I could alow my grades to drop to 5 in Economics and Language A1 and still get 40 points in total. So since you need 38 points, remember that you can afford dropping 7 points in total. I don't know how well you did in TOK/EE, but if you get 2 points from those, you only need 6 in every subject which definitely is possible. I imagine you are better in some subjects than others, so focus on acing the stuff you are good at and think of a way to get through the stuff you are not so good at. Good luck for the exams!

  9. Hey, I was just wondering after doing a few past papers, how strictly will the examiners follow the mark scheme when marking a paper? For instance paper 2 in Chemistry? I have done some of the Chemistry paper 2's, but when I mark myself, the mark scheme often has "marking points" which are given in different words from my answers, even though they have the same meaning. Also when doing calculations I notice that there are "marking points" that I sometimes do not write down even though I obtain the correct final answer. For the record, this happens to me when doing Physics past papers as well and it bothers me cause I don't really know how many marks I should award myself when revising. Surely, it is impossible to write excactly like in the mark scheme? So for those who have already finished with the exams, or for any IB examiner on this site... How strict are the IB examiners when marking a paper? Are they like children of the devil or do they award marks as long as the student gives a reasonable answer?

    When are complex ions formed?

    Yes! Complexes are formed when a metal reacts with ligands as Melissi is pointing out. However, not any metal will form complexes. Only the ones with high charge density (high oxidation states). For example, Na and Mg will not form complexes as their charge as ions (1+ and 2+ respectively) is not enough to attract the lone pair of the ligand. Aluminium on the other hand which has a charge of 3+ when it is an ion will attract the ligands. The most notable metals which forms complexes are the d-block elements in the periodic table as these have multiple and high oxidation numbers.
  11. Thanks for answering
  12. Hey, I was just wondering how important the Internal assessments in some subjects were. I know they usually are supposed to account for about 20 % of your final grade, but lets say I deliver my IA's in chemistry and I get the lowest score possible, but I get a 7 on the exams. What will my final grade in chemistry be at the end of IB? Anyone who knows?

    What are your opinions of Mitt Romney and Barack Obama?

    I would have voted for Romney if I had the chance... It is not because I am particularly fond of Romney, but rather because I think the US should have changed their president. Obama got his four years, what did he do? Not much... What will he do the next four years? Again, probably very little... All Obama wants is to sit on his lazy ass in the white house and enjoy a life of luxury and fame. Romney was not a good canidate, but at least he would have tried to change the state of the US for the better. But of course, we will see how things onfold the next four years. My bet is that little is going to change from the way things are now.
  14. Well, I would not say that it is fair that these people should recieve such salaries. However as someone mentioned earlier, there are few people who (in the end) are able to do these things (playing football, acting on TV etc..). The reason behind this I think is the fact that you cannot be taught these skills. It must be in your blood... While something like teaching is relatively easy to learn for anyone.

    Hot or Not? IB edition

    Some people call me a monkey, others just call me black. Not because we Norwegians have heard you Swedes pee in your gardens. Have to go though, nice hotting and notting you all.
