  1. The relevant quantities in this question are the 1) time 2) initial velocity 3) displacement 4) acceleration. The corresponding equation is s = ut + 1/2 * at^2 Let down be the positive direction. s = 4.81m, u = 12.7 m/s, a = 9.81 m/s^2, t = ? Plug the values into the quadratic and solve for the positive t. t = 0.335 s
  2. You should look for the subject report from any recent exam session. IB examiners will note how students and teachers misinterpret the criteria and list the common weaknesses.
  3. First of all, you shouldn't need to memorize over 20-30% of Chem SL. The time spent on memorizing in Chem SL would need to be spent on conceptual understanding in Physics SL. There is a clear timeline to memorization, but it is unclear how well you will fare if you have to understand a concept thoroughly. There is also a significant amount of conceptual understanding in Chemistry, in most of the units. I wouldn't know how much the jump between grade 10 and 11 is, since that depends on your school. I took Chemistry HL and Physics SL, and frankly I do like how the physics SL course is structured compared to chemistry. The Physics SL boundary for May is around 75 rather than 80, so the difference is big but not overwhelmingly big. But physics has slightly more critical thinking questions, where Chemistry questions are in general very straightforward. The chance that you will score higher in physics cannot be determined from the first month of IB. You should go with whichever one is more interesting to you, so that when the class does get tough, you will have the motivation to pull through. I can tell you in 2 years of Physics SL, we spent maybe 1 or 2 classes building circuit, so don't let that be a big factor. Also consider the historical performances at your school. That is more relevant than the grade boundary. If one subject clearly outperforms the other at your school, then choose that one.
  4. This is a picture showing the number of marks in each criterion, without additional details.

    HL Math EE

    We have some EEs in the file section but they are to paying VIP members only. You can also try your luck elsewhere on the internet.

    HL Math EE

    Math IA explicitly wants connections between different branches of mathematics, but it is not explicitly stated in EE. In addition, there is a greater emphasis on original thinking in the EE, so topics on modelling will generally not be as successful as they would be in the IA.

    Changing Subjects

    How are you able to take 2 classes in Group 6? You need at least one class from each of Group 1 through 5 to be eligible for the Diploma.
  8. There is no limit, but if the syllabus changes then you have to attend classes, which for most people, is just not feasible.
  9. @Maria00 https://www.ibsurvival.com/files/category/14-ib-syllabus-data-booklets/ Here you go
  10. It can show a great degree of personal engagement, without guaranteeing a 4 or even a 3 in the criterion. Ultimately, the shape of the interior of a can is somewhat simple (cylinder), even if the outside is bit more complex.
  11. This topic is now locked. Please continue to give thanks to Mr. Muench by liking his original post. @steve.muench if you want to add some important comment, please let any moderator know. Thanks!

    Math IA Help!

    It is against IB and forum rules to suggest a topic to others. Sorry.
  13. IB will not accept multiple works from you that are on the same topic, let alone completely identical.
  14. I think so. You should justify it in your IA.
