FAQ: How heavily examined is Topic 1?Aug 23, 2021
Does the IB examine students on Topic 1 (Measurements and Uncertainties)? Or is it just a physics-prerequisite chapter?
Soooo.... this is a difficult question to answer - depending on when your exams are and what level.
In 'normal' years, Chapter 1 makes up an average of 8% in HL and 9% in SL of your FINAL IB Physics mark. A huge proportion of Paper 3 is devoted to the concepts in Paper 3. By the way, that percentage takes into account your IA (20%). Soooo.. if you answered all the questions in chapter 1 correctly - it could be the difference of a whole grade boundary in your exams.
In 'covid' exams, paper 3 has been eliminated. That means that the average percentage devoted to chapter 1 in IB Physics exams is waaaaay down to about 1% in SL and 0.8% in HL Physics. This is because Paper 1 only ever examines Chapter 1 with one or two multiple choice questions.
So, if your exams are 'covid' exams, then you really do not want to prioritise chapter 1 in any revision. If your exams are after May 2022 - then you really DO want to prioritise Chapter 1.
All of the above advise depends on the IB being consistent with their exam writing. For the last few years, things have been very consistent (e.g. Q1 in Paper 3 is a data analysis question, etc). It would be out of character to change the goalposts significantly (especially in these very difficult times during Covid) without lots of warning first. Therefore, I think you can be pretty confident of the predicted percentages above.
Does that make sense?
I've been teaching IB Physics since 2004 and have helped (literally) thousands of students prepare for IB physics exams. I could literally write pages and pages of advice but I've written it all so many times before that I've just pulled my advice together into a couple of freebies.
You'd be more than welcome to grab either of these. Hope they help and good luck!
