AP Computer Science A - Unit 7: ArrayLists 

➡ Great AP CSA Exam Review Book: amzn.to/3RGN8ii ⬅ 🎧🚀 Fun Sci-Fi Audiobook For Educators: amzn.to/3TItymu 🪐🎧

My test is tomorrow and I’m so glad that this video was released before. I always watch these videos while smelling my AP CSA perfume then I smell it again during the test because smell has memory.

Thanks for the video! I like how this came out the day before my test. Pretty good pace, learnt a lot of information. ✅

Hey Mr. Barnum, wanted to give you my thanks as well. This video somehow addressed every single confusion I had about ArrayLists and explained them perfectly. Two gold star stickers for you haha! Keep it up! :D

Hey Bill. I just wanted to thank you for making these videos. I used some of the simple code guides last year to help me get a 5 on AP Computer Science Principles. Now i’m using your more complicated reviews to study for my AP Computer Science A exam in May. Thanks for all the great content!!!

Appreciate your dedication to these videos! Right on time with my course, as I make up my test tomorrow. Thank you!

I find your videos really good, especially for reviewing. When will you be releasing unit 8 it is the one I'm struggling on?

Just curious where unit 8 is? Is it in the works? ETA? I love these ♥

Great video, and I think the pace of the video would be perfect if it was a minute or two longer.

Can you please add sorting

8:55 - 13:55
