• Do we have data for difficult problems?
  • It seems good to use them.

Solved Paper 1 IB past paper IBPhysicsP1

• Thoughts

  • Looking at the content, pulling out the formulas, and narrowing down to the correct ones seems to be the flow of solving the problems.
    • If you can have intuition without even looking at the formulas, it will save time.
    • I want to increase the areas where I can do this.
      • For example, I still have a vague memory of the slit diffraction part, so I have to look at the formulas every time.
  • I was surprised a few times by problems of that type?!
    • Q. which of these caused a paradigm shift?
    • Q. Estimate the momentum of a falling boy (you have to estimate that the boy’s weight is about 50kg)

• Solved ones (✅ means reviewed)

  • M16✅

    • 25/28, not bad
    • I haven’t solved the problems in the unit that I’m not good at yet, so I want to solve them later.

  • N16✅

  • M17TZ1✅

    • 31/35, well done
    • The time allocation was perfect.
      • I might want a little more time for review?
      • However, there were no careless mistakes this time, so it might not be necessary.
        • (There are some that I might have been able to solve if I had thought a little more)

  • M17TZ2✅

    • I still don’t know 33.

  • N17

  • M18TZ1

    • 34/37
    • I don’t know 33, EM induction.
    • I also don’t know 35.

  • M18TZ2

    • Around 29/37

  • N18

    • 31/37

  • M19TZ1

    • 31/40

• The accuracy rate is better in the first half, why?
