AP Computer Science 2011 – Free Response #4
I’ve covered the first and third AP Computer Science 2011 Free Response Questions. Today I will conclude with the fourth question. I skipped the GridWorld question and I probably won’t be covering it. The fourth free response question is about encryption. Using a two-dimensional array of single character strings, you’re going to encrypt a message [...]

Well, it was all about GridWorld and I’m not really a fan. I don’t have API access and writing and making testable and runnable code for it isn’t exactly ideal. [...]
AP Computer Science 2011 – Free Response #1
Last year, I blogged about the free response questions from the AP Computer Science exam. This year, I’m a couple of days late but, I managed to see and work on the questions. I have to say that the free response questions from this year are at least on par with last year. Free Response [...]
APCS FRQ Soon!
Over the next few days, I’ll be pushing out my answers to this year’s free response questions from the AP Computer Science exam last week, just like last year. Free Response Links FRQ #1: Sound FRQ #3: FuelTanks & FuelRobot FRQ #4: Encryption I may or may not cover FRQ #2: GridWorld. If anyone else [...]

My AP Calculus class finished its last unit before our review for the test in May today. The test was on solids of revolution. Personally, while I love calculus, I’m tripped up by the different scenarios like rotating using disks on dy or using a shell on dx. I wrote a little study guide to [...]
