  1. If you've already covered all Biology topics, even briefly. then at this point there's not much more to do. A holistic review of all the topics is better than in-depth understanding of only a few topics, and you've accomplished the former already – all you can do left is just quickly review as broadly the topics as you can, particularly the SL chapters which are the most heavily weighted, before Monday. Past papers don't really work for Biology so much as comprehensive review, so your time is better spent making summary sheets of topics you're weak in etc. As for Maths HL, you have two options. If you're struggling in one or two topics but fairly capable in the rest, then just hammer away at Past Paper questions on those topics. However, at this point you should already have an adequate understanding o all the topics – it's recommended you just drill past papers now, ideally 3-4 full Papers each day (with a balanced mix of Paper 1s and Paper 2s, with the odd Paper 3) and learn as much as you can from your mistakes. I don't know your skill level in those subjects, nor the grades you're aiming to get, but these review strategies will work very well regardless of those factors. I would suggest spending more time at Maths HL than Biology, again because it seems you already have the necessary breadth, if not the depth, which is adequate for a 5 – maybe a 6 or a 7 if the topics that come out are your best ones and your IA is good – and there's not much you can do about that with only 5 days remaining.
  2. Not really.... the relevant calculations have been done already. It is possible, given that you obtain close to 90% of the marks.
  3. With only a week left before exams, there isn't much to brush up on anymore – was hoping to refine my exam approach to the best of my ability and avoid any easily avoidable mistakes. From your sources, is it losing one mark per question you screwed up significant figures for, or -1 mark per the whole paper? The latter I think, is no longer the case for Maths SL and HL of the 2014 syllabus.
  4. Thank you for your response! Therefore, leaving my answer in 0.776313123123123123123123 would still be acceptable for the complete marks right? With regards to a 0.775 though, I would still earn working marks, but only lose the final mark right?
  5. I'm rather confused if its required by the IB, on penalty of losing marks, to always leave answers in 3 significant figures. Different sources tell me otherwise: a mark scheme from the old Maths SL syllabus (pre-2014) states that a -1 mark for inaccuracy be applied to the whole paper, once, if there is any instance of inappropriate significant figures in the answer. However, the mark schemes for the current syllabus are very vague regarding this, and I cannot interpret anything whatsoever. My Maths teacher is also rather unsure about the importance of significant figures, whereas DP coordinator says you can leave your answer to 99999 significant figures if you really want, especially for GDC-related answers in Paper 2, and there is no penalty whatsoever. But also, what if there discrepancies in numbers for Paper 2 questions? For example, if the answer is 0.776, but my answer is 0.775, will I receive no marks for the final answer whatsoever, or only be applied a -1 mark for inaccuracy? The following is stated in the mark scheme for the May 2016 Paper 2 TZ1: 10 Accuracy of Answers Candidates should NO LONGER be penalized for an accuracy error (AP). If the level of accuracy is specified in the question, a mark will be allocated for giving the answer to the required accuracy. When this is not specified in the question, all numerical answers should be given exactly or correct to three significant figures. Please check work carefully for FT. This is really confusing. I MUST give all numerical answers exactly or correct to 3 s.f. But if I don't, will I NOT be penalized, or will I STILL be penalized? Additionally, I'm wondering if there are differences in accuracy policies between Paper 1 and Paper 2. I'd like to think that significant figure inaccuracies will be less prevalent in Paper 1, therefore if the IB follows this line of thought, will penalties be harsher? Hoping someone can help clarify this. Thank you.
  6. There won't really be development questions (apart form the rare 4 mark question on an aspect of the Development Syllabus). But because there's no calculations involved in that section of the syllabus, focus on Micro, Macro, and International calculations. On your final exams, Paper 3 will be right after your Paper 2, so the night before it's highly advisable to focus revision on Macro and International, given the major overlap they have over the two assessments. Development is something you should revise as well, but a lot of it is arguably "logic" and essentially boils down to empowerment of women, environmental sustainability, education, and healthcare. It's really just the aid vs trade and development aid that are whole new content that you would need to revise. Usually, the Paper TENDS to have a Micro, Macro, and International question. But that's hardly for certain – you might end up with 2 Micro or 2 Macro questions. It's unfortunate your exams are in 2 weeks, but you'll need to find a way to cover as much of the syllabus as possible – focus on breadth over depth at this stage. Try to be able to perform most of the calculations e.g. subsidies, tariffs, quotas, taxes, demand and supply, exchange rates, price controls. You can forget about national income statistics and CPI and just hope they won't appear given their presence already in past year papers. Best of luck!
  7. Can you collect sufficient quantitative AND qualitative data from which you can use to answer your Research Question? That is really the most important thing to a science research investigation. Regardless of the ethics, if the answer to the above question is "No", then for the sake of a decent grade, the investigation needs modification/be discontinued (though thinking about your experiment, you can perhaps conduct a survey on amount of sleep, or the time taken for a person to sleep after using computer/electronic devices).
  8. At this point, Maths SL Questionbank questions no longer match the recent questions in terms of difficulty. I would advise sticking to Past papers from now down 'till May 2013, or even better, doing some Maths HL Section A questions on topics that overlap with the SL syllabus. Alternatively, which is what I'm doing currently, you can focus on specific weaknesses from the syllabus and solidify your skill in that area – Questionbank will be ideal in this scenario.
  9. If you look at the Analysis descriptors for levels 1-2 and levels 5-6: 1-2: The report includes insufficient relevant raw data to support a valid conclusion to the research question. 5-6: The report includes sufficient relevant quantitative and qualitative raw data that could support a detailed and valid conclusion to the research question. I would say your IA wouldn't get more than a level 2 for the Analysis criteria if you cannot get an adequate amount of quantitative data (ideally 5 different variations on the Independent Trial, with at least 3 trials per variation). Moreover, although it's only part of the Analysis descriptor, your Evaluation, Personal Engagement and Exploration criterias will also be affected by your inability to collect sufficient data for processing to answer your research question, so overall it's not going to be good news as IA marking tends to be holistic. A word of encouragement though: I'm not sure about the deadlines set by your school, but you still have a long time to work on your Bio IA. I only started mine on February this year with the topic and experiment (cutting it real close ik), and actually only finished the write up by the end of March, but imo is one of the best lab reports I've ever written. Time is definitely on your side, so what I would recommend is modifying or changing your topic to one that can collect a suitable amount of quantitative data from which you can process and draw conclusions from. Good luck!
  10. Thanks for the sketch – the answer is indeed 5 isomers. I agree with you – though cis-trans isomerism is still stereoisomerism, it would be great if they also at least hint on whether or not E/Z isomerism is required.
  11. Wondering if anyone can answer the following question, and the explanation behind it, as I have trouble differentiating between isomers for cycloalkanes. Thank you!
  12. I like Ranger's Apprentice, The Brotherband Chronicles, The Lord of the Rings, The Hobbit, A Song of Ice and Fire (did the book series for my EE), Percy Jackson & Heroes of Olympus series, and mostly other fantasy series. When I was still English Lang Lit HL, I red The Great Gatsby, Atonement, and Macbeth for my Part 3 works. As just an SL student now, I only read The Handmaid's Tale & The Metamorphosis for Paper 2. Generally I really don't like the works I'm reading in the course (you can probably gauge my terrible reading ability based on my likes and dislikes)
  13. The IA in Chemistry is worth 20% of your overall grade. That means your IA, which is a 6/24, will contribute (6/24) x 20% = 5% to your overall grade, out of 100%. The other 80% of your overall grade comes from your external exams (20% Paper 1, 40% Paper 2, and 20% Paper 3 for SL; 20% Paper 1, 36% Paper 2, and 24% Paper 3 for HL). If you're aiming for a 7, it is still possible with only a 6/24 in your IA, but that means you're going to need to attain about 92% on your final exams, bringing up your overall score to about 78%. (Calculation: 92% x 80% = 0.73 = 73%. 73% + 5% = 78%) And the same goes on to attain grades of 4, 5, or 6 – essentially you're going to need to perform much much better on your exams to make up for your IA.
  14. Additionally, a senior of mine who scored a 7 in the May 2016 Bio HL exams advised frequent reading. Notes in Biology tend to be more important than for Physics and Chemistry, and past papers are almost useless. Do a lot of taking notes and reading, making sure you understand stuff. These are what's essential for a 7.
