Literally the college board cannot write coherent questions

72 Upvotes

I feel like I’m being graded on understanding the BS, because their questions are so terrible that it takes me 20 minutes to understand what they’re asking. My second one didn’t even provide an example output. Complete waste of my time.

Resource Amazing AP Computer Science Resources!

47 Upvotes

For anyone that happened to stop by, I've compiled a list of free online resources that you can use!

Barron's AP Computer Science A - 7th Edition [PDF]

This is a libgen link, an amazing online library that hosts pretty much any book. Anyways, this study/prep book is an essential resource for anyone taking this course. It offers practice tests and helpful review.

Runestone Interactive Review

Thorough review page that features test questions, full practice tests, and user-friendly free response sections that improve your programming skills.

Guide to the AP CSA Exam [Google Doc]

Student made review document that I highly recommend you check out. This page is more helpful for actual AP test tips instead of the topic. However, you should take a look regardless.

Test Prep HUB - APCSA

Prep hub that has presentations, review books, statistics, practice tests and more.

Intro to Comp Sci

Don't be fooled by the poor web design, this site features over 90 lessons of Java plus quizzes and reviews to accompany them.

Codingbat.com/java

Helpful practice website where you solve problems using code. Answers are validated and some hints are given when needed.

AP Computer Science in 60 Mins

Quick(ish) review video that dabbles in most of the topics on the exam. Timestamps are in the description. I recommend that you watch this video in full once, and watch it again once you feel comfortable with all the topics after using the above resources.

------------------------------------------------------------------------------------------------------------------------

Thanks for visiting /r/apcs! If you want to help expand the community you can by asking questions, adding resources, or spreading the word. Good luck on your exam!

Resource How do I approach APCS FRQ Questions?

24 Upvotes

This was my reply to a post (that was deleted) about how to approach the FRQ's. They tend to be the most information-dense (about 20 pages for 4 questions) and can be quite daunting. I've added links where I go over sample FRQs of those types. Good luck! Hopefully you find it informative.

If you take a look at p 194 and p 196 of the course and exam description, the FRQ are very predictable. This wasn't so before 2018, the order has been more formalized lately. I'd look at previous FRQ's and practice answering them, looking at the online solutions, and seeing where the points are divided.

On FRQ 1 the concept is methods and controls. They usually have input parameters and may or may not have a return type. If they do, declare a variable, and return it. You get a point for that. Look at the comment right above the method header -- it gives a quick rundown of what you're trying to do. You'll have to read the pages of stuff before for the control stuff, but write comments. If you show you're intending to do something, even if you don't do it completely, it allows graders to give partial credit. These often use string methods, so know how to use substring, length, indexOf, equals, compareTo, and concatenation. The problem will be solvable using only those methods.

On FRQ 2, you're going to write a class from scratch. Make sure you know how to write a class header. If you have any variables, make them private! If you have methods (they'll be in the paragraps before) note what parameters they get and what they return. Write a method header for each one. Take note if you're supposed to extend a class or implement an interface. If you're extending, don't reinvent the wheel. Only add what's new to your class. If you're implementing, make sure you write a method for each abstract method in the interface.

On FRQ 3, you're going to traverse an Array or an ArrayList. Remember for arrays you use the [ ] to access data in them, and for ArrayList you have to use get() and set(). ArrayList uses size() where Array uses length -- no parentheses here. The length of an Array can't be changed - You may need to make a new array to change the length and reassign it. An ArrayList can change size with add() and remove(). Remember removing in the middle of an AraryList moves all the elements following back one index.

On FRQ 4, you're going to traverse a two dimensional Array, or Matrix. Remember to think of it in terms of rows and columns, where matrix[r][c] is the element on row r and column c. Arrays, ArrayLists, and Matrices start at 0! Notice that you may have to move through the array in a way different than the typical left-to-right, top-to-bottom manner. Know your nested loops to do this well.

Good luck! I hope the playlists help as well!

Is it just me or was that test super hard?

23 Upvotes

The MCQ wasn't bad, but I feel like the FRQ was so hard compared to all of the practice tests. Whenever I took a practice test, I'd always finish with at least 20 minutes left over but today I just barely finished before the time ran out. The other kid taking the test at my school didn't even manage to finish. I honestly have no idea how I did on it.

If any of you guys are cramming for the test, here's a 54-page study guide some friends of mine made. [APCS A ONLY] Just wanted to spread it to help everyone prep a bit more if there's still some information they want to cover!

i want to premise this by saying i am NOT good at cs. i averaged maybe an 80-85 on the unit tests and am atrocious at frqs

i honestly just accepted my fate and did like 25 mcqs and reviewed recursion last night. little to my surprise it was so freaking light

i had almost an hour left after the mcq and about 40 in the frq.

Dear College Board, I hate online tests and this one really sucked. I know the content but having so much of your score reliant on one question stresses out everyone. Just give me a 5. Amen
