Notes on Collegeboard Questions from AP Classroom

Initial Overview

  • Requires lots of logic and mental gymnastics to solve majority of problems
  • Strong mix of word problems and coding problems
  • Easy to work with and complete with relevant knowledge
  • Broad coverage of outside tech knowledge (like of the IETF) and public encryption skills

PROBLEMS I NOTED

Example 1:

  • Big logic based question, tough because the wording wasn’t very specific
  • Two options looked plausible to me - not affecting the number of messages per day and heavily lowering the size of messages per day
  • Interesting problem, not immidieately clear how it was computer science related, more stats based
  • Opened it up to me on how APCSP covers more than just coding

Example 2:

  • Also tough because it required some specific knowledge I didn’t have
  • Had to look up if digital certificates and IP registration for every device was real

Example 3:

  • Required me to research redundant computer routing, after that it was just fun to analyze logically and find the one that only had one working pathway

Example 4:

  • This was a cool problem, needed to learn basic computer encoding
  • Learned about lossless vs lossy encoding algorithms
  • Learned that it’s only useful to byte pair encode when the byte specifically repeats multiple times

Example 5:

  • This one was definitely hard to understand
  • Pseudo format AND and OR statements I referenced in the guide they gave
  • Generally learned difference between needing only one to be true for the whole statement to output true vs needing both to be true to output true

Example 6:

  • This one was expressely hard to wrap my head around logic wise
  • Interesting to analyze the flowchart, kind of just one big if function displayed visually
