• Study plan until IB Exam Nov 2021:
    • For now, topics 8-11 are still disastrous for me.
      • I will use Kognity to clarify any uncertainties and solve Pearson WS.
      • (This is the minimum requirement)
      • I probably have a vague understanding, but I need to consolidate it by summarizing in notes or something.
      • Then, I will focus on memorizing the details.
        • Anki, which I received from (aka), seems to be versatile for this. I’m grateful for it.
    • After that:
      • Solve Pearson challenge problems.
      • Solve Cambridge Textbook Problems.
      • Solve Past Papers 1 and 2.
        • However, I feel that understanding the concepts is a bigger issue than time allocation, especially for Chemistry.
        • So maybe it’s not necessary to time myself solving past papers?
          • Well, but as understanding deepens, I will be able to solve more questions, so time might become tight.
        • It seems important to concentrate and work on these topics.
        • Regardless of what I do, the goal is to fill in as many gaps as possible. So solving past papers might be killing two birds with one stone.
        • Notation:
          • v: Solved all, not checked yet.
          • ~: Solved partially, not checked yet.

  • Online Period Notes:
    • There are many past papers for P1 and P2 that I completed hastily.
    • I struggle with the ones I completed hastily or left blank, so I want to cover those later.

  • Guide:

  • First, I will solve the copied versions of Pearson for all subjects and clarify any uncertainties.

  • Then, I will do the Mock exams.

    • I might also solve Pearson’s Challenge problems.
    • Since I don’t have them with me, I might borrow the textbooks from school and use zala.

  • Chapter 8:

    • I haven’t fully understood it yet, so it seems better to go through it again later.
    • pH/pOH values are for when a substance dissociates into ions.
    • The fact that pH+pOH=14 is because as pH increases, the equilibrium shifts to the left (the side where the substance doesn’t dissociate) due to Le Chatelier’s principle.
      • Originally: A small amount of H2O is already dissociated, almost in equilibrium on the left side.
      • When an acid is added and pH increases, the equilibrium shifts to the left and pOH decreases.
        • For a strong acid, pH increases by the same amount as its concentration, for a weak acid, it increases slightly less.
