  1. The main question is whether OP understand topics but struggles with some IB questions or is just confused about the topics. In the former case, it would be good to practice IB problems. If the second case, it's better to review notes and work on simpler problems. I concede that the approach to just do as many IB problems as one could is not a short term solution. Then on the other hand you will not be prepared for the exam if you are unfamiliar with marks allocation or even question styles. There is very little time in the exam to sit and ponder on a question.
  2. There is no better way than doing past papers. It's good that you know which area to work on so just do questions related to your weak spots. Start with section A then move on to section B. If you have any questions you can ask them in the forum. Best luck!
  3. In general you should do the EE in your best subject. Mine was math and I scored well in my EE. It appears that you will use some separations methods to get the antioxidants. It could be better to do a reaction because you have more to talk about. But if you know the methods, it's perfectly fine. The hard part, obviously, is that the methods may be out of syllabus. The methods most accessible to high school students, such as titration and spectrometry, have greater precision. I am not sure how you would separate/quantify the oxidants. It could be riskier to a topic with lots of extra readings but the topic seems fine.
  4. There is no overall generalization that can explain why your grades are dropping, but you have to look at specific circumstances. What are you getting wrong on the tests? How are you approaching homework and tests? Why do tests feel different from homework? Once you identify the causes of the issues then you can solve them. Talk to top-performing students from your class or from HL and see what they are doing differently. In general by each test, you should be able to solve most homework problems without looking at your notes or the solution. A lot of it could be just doing more practice to get the speed up. You should look for improvements in study habits and what used to work may be no longer sufficient.
  5. The math in Chemistry SL is mostly plugging in values into a formula and doing basic unit conversions (like mass <--> mol). Math does not constitute a large percentage of the course as it will be heavily conceptually based. However there are some sequential calculations you have know for the exams and it may be slightly more challenging to grasp certain concepts if you do not have the insight on the math. Because it is SL and not HL, some concepts are presented more disjointed and you may need to occasionally memorize without fully understand everything. In general chemistry is not required but it may supplement your application as admission offices may be looking for at least Math SL not Studies and chemistry is often recommended if not required. Judging from historical data, very very few ESS students get 7s and it may be attributed to the lack of teachers qualified or experience to teach such an interdisciplinary course. Global politics is a new course and teachers may also lack experience in teaching it. ESS and GP will generally not help in your undergrad applications and I cannot definitively speak about their difficulty relative for Chemistry SL. These are type of courses in which if you get a 7, it may nudge your application bit in your favor, but otherwise they are not useful at all.
  6. You can just mark X or write in the appropriate letter because the boxes are big and it's going to take too long to shade in. The exams are graded manually.
  7. It sounds interesting and easy enough to explain the theory and develop a procedure. There may be some additional reading you need to do to fully explain how sunscreens work (on a molecular level). I think you need an additional independent variable, such as concentration of chemical, in addition to identity of chemical. Wish you the best!
  8. According to the IB official records, there are 31 DP schools in Sweden. https://bit.ly/2EEXszD You can email them individually to see whether they do November exams.
  9. It makes more sense to have around 1/3 theory and 2/3 experiment. The latter also includes discussion of results and error analysis. Most of theory is discussed in the introduction, in which you can outline importance of studying cosmic rays and theory behind your experiment. Excess theory, such as particle physics in general, is not as relevant if it does not directly impact decision making in your experiment. But if the theory is vital to how your collected data, then it is useful to be included. Think of the EE as writing a detective story. You need to have problem/case (EE topic), context- or experience-driven methodology (theory and its relation to experiment set up), clues (data), putting clues together (analysis of data, possibly backed up by theory), solving case (conclusion). The theory will be mostly presented in beginning of EE but may be partially weaved into rest of EE if it is helpful.
  10. There are 2 parts to the solution 1) Break large tasks into smaller ones 2) develop good study habits. Now that IAs are way behind you, there is not really any due date to keep you on track. For each course, you should set goals of what you need to accomplish each week. For example this week could be skimming through all material once and identify weak points. Next week could be getting help on those weak points, and a week for doing past papers. You can prepare such goals with a friend, and at the week's end you can test each other see how much was reviewed and how the goal was accomplished. Being part of a group alleviate feelings of isolation and may motivate you to work diligently. What is taking up your time from studying? You should work to eliminate those. For example if you are browsing social media, you can make post saying you will be studying for exams and hope others will keep you on track. Try keep study sessions about 5 minute break for 30-40 minute CONTINUOUS intensive studying, without distractions. Go through at least 3-4 sessions each day. One could be in your lunch break. Let your family know of your plans and ask them to monitor your progress and provide emotional support. In many cases if you have not gotten too many 5s or lower and it's just 1 or maybe 2 point below offer, you can still write to them to see if the conditions can be loosened. In many cases the admissions office can still accept you.
  11. @Mais I understand. I want to reiterate that in ANY undergrad science program, you need 1-2 semesters of college physics. You should take some high school level physics (which is not the same as Physics HL) to find out how you truly feel about it. When you apply to universities, most science programs require high school physics for application to even be considered. Most arts or social sciences programs do not have as strict entry requirements, so it's not as if you are closing doors by choosing physics over another course. In summary, you cannot treat DP same as MYP they will be more rigorous and the way you feel about a subject may change (for better or for worse). If you have had difficulties in physics, you should look for ways to take an easy physics course just to be sure you satisfy potential university entry requirements. Before you submit your course choices, you should convince your parents that your decision is acceptable. Otherwise potential conflicts could contribute to unnecessary stress in addition to DP.
  12. If you knew for sure that you are going into the sciences, maybe IB is not the best program for you. Because of the limitations of IB, you may be better off to going to a STEM focused program, in which you can take at least 3 sciences. I am not sure how much exposure you have to sciences outside of school, but going to a science-focused school allow more time to partake in science extracurriculars and/or reading scientific non-fiction to learn more about science outside of the classroom.
  13. If you are considering taking a third science, you might as well take Chem/Physics HL and Bio SL as a 7th subject. ALL sciences need some physics so it's best to take it early, in high school. Computer science is not useful for the sciences in undergrad, it's more useful for engineering. Some up and coming majors include biomedical engineering, biosystems engineering, nanotechnology, and material sciences, which draws upon multiple sciences and knowledge.
  14. In my understanding, context of a literary work only goes up to publication. It does not generally include the critical responses or reception of a work. I do not think EE is suitable to focus on countries banning a work.
  15. You are HL, yes? If so, there is no point explaining DeMoivre's theorem or Euler's formula because they are in syllabus. You would demonstrate as much knowledge just by using them correctly in problem solving. Because there is limit to what teachers can say to a first draft, you should bring it to a fellow student (possibly in Year 2) to look at it from student's perspective. It's discouraged to send them on IBS in case plagiarism checker picks it up. I like the inclusion of phantom graphs. The content, for the most part, is relevant and good. The problem lies in the organization. Think of how you are taught to structure essays. You cannot just have arguments disjointed in the paper, you have to have a central idea, and explain your reasoning systematically. In that sense, your IA should have an overall goal. Because you are not solving a large problem, you need to first find the overall argument to your exploration then find some way to group ideas together to support that claim. It could be showing why complex numbers are useful. Then, you can have a section for visualizing complex numbers, and another one for applying them. Or you can organize by connections to other parts of syllabus (algebra, functions, trig). You should go beyond proofs, and show some interesting problems that can be made easier with complex numbers or a representation. I suggest you look through HL past papers on complex numbers and trig. They have questions on using complex numbers to find exact values to some trig expression. It's somewhat rare to see complex numbers with hyperbolic functions because for example cosh(x) = 1/2 (e^x + e^(-x)), if x is complex, cosh (e^(iθ)) = 1/2(e^(e^(iθ)) - e^(e^(-iθ))). For the differential equations, the differential equation d2y / dx2 + ky = 0 has circular trig solutions if k > 0, and hyperbolic solutions if k < 0, similar to the discriminant of a quadratic. Something like this could be worth while to discuss, except for that differential equations are too advanced for a year 1 student. The past papers may be helpful to provide some starting points.
