I'm glad you found it useful, Samuel.

[@cubingpro9877]

Taking this in the upcoming school year

[@BillBarnum]

That's great!
A small word of caution to future AP CSA students. If you look ahead to future units, it can seem overwhelming because your teacher hasn't taught you the fundamentals yet.

[@abdullahgokturk1639]

Thank you

[@BillBarnum]

Thanks for the comment, Abdullah!

[@winslowsolomon7882]

Hi Bill! Your videos are very good resources. Would you recommend your 60 video ap cs a course or this one more? Thanks

[@BillBarnum]

Hey Winslow,
By and large, the Unit videos are reworked versions of the 60 video APCSA sequence.
There is some stuff added and removed, but the content is largely the same but organized into the topics in the unit.

[@winslowsolomon7882]

@@BillBarnum cool. thanks!

[@seppuku8716]

I don't know why at 19:47 it increases in the stack but not in the actual x

[@BillBarnum]

Don't expect to see this on the APCSA exam, but here is an explanation:

[@altxd2567]

is this course enough to get me through the foundations of the AP Computer Science A?

[@user-uv8kg7cc2r]

Does this cover anything in unit 1 that might come in the exam?

[@BillBarnum]

It's meant to be a broad overview. I recommend getting a review book to practice for the exam.

[@elizabethlee2743]

Hey im in 10th grade and have no prior knowledge about coding or computer science, shohld i still take AP computer science A ?

this feels a little slow but also pretty cool

[@BillBarnum]

I try to err on the side of too slow but I encourage you to watch the videos at 1.25x or 1.5x speed.

[@felixhang1197]

Im doing the late exam and I have a week left, wish me luck.

Good Luck!
