- Hi Robert,Apologies, reading that again I can see it is misleading. I meant it with regards to preparation, in the xam, students must get clean copies just as with AA. Thanks for bringing this to my attention. I will edit it.
- Hi, I am going through the resources for AI as we just recently offered AI instead of AA in our school...I notice that your advice is that students can take their own annotated formula booklet for the exam however the IBO assessment guide refers...
- Hi Celeste, apologies, the website's security is being upgraded and there has been a few access issues on some pages. I've checked and moved the page so it's more clear in this Exam Advice section (please let me know if that's now working ok,...
- Also, it's my understanding that students must write in ballpoint pen only. Has this changed? ("Accurate graph drawing and sketching")
- The "Top Marks" link still gives me this: "This page cannot be found. If you have any questions, please contact us." I'm logged in, even.
- Hi Celeste, try the link again, I have just tested it from my end. Regarding the slides - sorry thats not possible as it stands. You can share the page with your students though using student access. thanks, Jim
- Hi there, If you click on the 'eye' icon underneath the question it shows you the solutions. Let me know if that works for you. I have just tested from my end and it works, thanks, Jim
- Q2) (b) (A sample of 35 students from 600) My students and I found the word Example confusing. Why not just delete it? I would also delete Step 1 and let students decide where to start.In your solutions you have no Step 2, which compounds...
- Q1) (b) (Systematic sampling)I would clarify in the question that "Not relevant" can be used more than once.My critique of the posted solutionIn the sources I have looked at recently, selecting a random starting point is an essential element...
- These are good questions: they prompted a meaningful discussion in my class. But I have several issues with your proposed solutions.Q1) (A sample of 35 students from 600)(a) If the students are seated in the school theatre in random order to...
- Q11b) and Q15b) also contain apparent errors
- Q8 a) seems to be two errors in final column of table. I have calculated 0.0716 probability and Expected Frequency 215
- Hi Benson, Q8a(i) solution is correct, but working is missing a "75", thanks for spotting this👍, we'll update accordingly.Q4: this is a borderline level6/7 question to check students' conceptual understanding. Areas of trapezium...
- Thanks Oliver; all sounds reasonable! A couple more things I just noticed:-the solution to Q8 a) i) seems to be missing a 75 in front of the brackets -regarding Q4, candidates would only be expected to deal with intervals of equal width,...
- I can not see the answers to 2C. The link does not work
- Students can be given access to this page with student access so that the above can be easily shared with your classes. Hope that helps.
- The "student notesheet" below the teacher slideshow is designed to offer this support for students. Our apologies, our idea is that students can easily view these for revision purposes from their phones anytime/place, or on computer,...
- Hi Benson, insightful and helpful questions as always. Q7 I think would be on the boundary of the syllabus (level 6/7 option) if it was instead written (cosx)². Students are expected to be able to use their graphical calculators to plot etc...
- Hi, wouldn't Questions 7 and 11 also be HL only?Question 7 because SL students wouldn't be familiar with the notation cos^2(x), and Question 11 because f(x) < 0 on 3<x<4.Thanks,Benson
- The "Top Marks" link above does not work. Also, can we download a copy of the powerpoint above, so that we can edit it?
- Hi, do you any basic practice for using the integration of x^n rule, similar to the way you have practice for differentiating x^n here (the "Deriving 1" and "Deriving 2" problem sets)?https://www.thinkib.net/mathapplications/page/30747/sl-calculus-conceptThanks,Benson
- Apologies, I have fixed that now, Thanks, Jim
- Apologies, I have fixed that now, Thanks, Jim
- I can't give student access to this page.
- I am not able to give student access to this page.
- Yes I also want to share this with my students. Can you please make it downloadable?
- I agree, that for question 5, the height of the trapezium should be 25, not 50
- Hi; for the second set of IB exam style questions, I find the rate given as "r cm/min" a bit confusing. For 2 marks, we are effectively just substituting r = 5 into dV/dr. Why the need for the cm/min?Why not just ask for the rate of change...
- Hello how can I get the above slid in PPT? It is really well organised and will make the learning experience for Graph theory much easier. Regards.Benard
- Do we have impedance in MAI HL syllabus? I have not seen in the guidebook it is mentioned anywhere. Can you please confirm?
- Hi, are there solutions available for the inverse functions activity above (the one where students fold the paper)?Thanks,Benson
- Hello! Agreed for Q4 a).Q5: how is the height 50 km?
- In the first question, 4th column is wrong in M
- fixed - thank you
- Hi Jim, I think Q2 also has some incorrect answers. And there is still a reference to the old incorrect answer of 4.33(%) in Q5. Thanks,Benson
- I think you may want to reword question 16 and remove the word gypping.
- Syllabus of AI HL does not include impedance or parallel connection. I guess use of Euler form of complex number suffices the need to find sum or difference.
- Hi, do you have any resources for direct and inverse variation and/or cubic models?Thanks,Benson
- There is a mistake in 6(a). It should be x^2+4x-1 = 0.
- Also, the wrong question appears above the solution to Q2.
- Hi, I don't seem to be able to turn on student access for this page. As in, the button just doesn't show in the top left corner the way that it does for other pages. It just says "teacher only page" where there would normally be a student access...
