AP Computer Science AB Exam

Recommended Posts

Hey everyone, im in high school right now, and im planning to take the AP Computer Science AB exam (on tuesday) and i was wondering if you all had some last suggestions on what to study. I took the A portion last year and passed with a 4, after doing a semister of studying on my own. this yeah i have done the same as far as the independant study, but i wanna get that 5 and was hoping that you all would have some good advice as to what i could do to bump my score this year thanks in advance! P.S. This is not a last minute desperate study cram kinda thing ;-)

Heh, I would make sure you know the different kinds of data structures (list, queue, stack, tree) and how they work. Practice analyzing recursive functions. Finally, know (pre/post/in)-order tree traversal. They always ask at least one question on those I think.

Good luck, if you did ok on the A and have been studying hard you'll do ok on the AB

i feel confident on the recursive functions and the tree-traversal.

i will use some more time to the types of data structs.

thanks :)

Hey, I took it last year(AB) and got a 5. I would recommend going through an AP prep book and studying and doing all the problems. Also make sure you are good w/ the marine biology case study.

I'm also taking it tuesday. I took a practice test and got a 5, but what i still needed work on was knowning the runtime complexities of the different sorts and when to use which sort. (There where 3 questions i missed because of it). Good luck... btw- I couldn't believe how much code base they had already made for the test

EDIT: The marine case study is what I was talking about with the large code base, I also forgot, know a lot about trees. Think trees, trees, trees

They're still using the marine biology case study? They've been using that one for years. Back when C++ was still the language, oh those were the days. I was going to suggest you work on pointers, but now everything is Java. In that case, work primarily on data structures, algorithms, and recursion, as others have said. I never took the AP exam, but if it's anything like the IB high level CS exam, then they really drill all the good stuff.
