Hi! I've just done my P1. Thank you so much for these videos!! I used them before my mocks, and before the exam (not cramming hehe) and they have been a life saver for revising Let's hope the leaks stop 😭
Can you please do Option D also? As there aren't any proper structured sources for OOP specifically for the IB... so it will be really really helpful! (Also I just want to say by making these vods you are really making our lives easier atleast mine and i'm very greatful for that:)
This saved me so much time. incredible. For the binary tree question around 49.00, would we still get the marks if we put Larch as our root node instead of Holly or Elm?
I think you are confused about stacks and queues being lifo and fifo, I saw you in the other video made the same mistake. Queue is fifo and stack is lifo. It's just dequeue(first element that was enqueued is the first one that is dequeued) vs pop(last element pushed is the first one popped).
Guys, when deleting the root from the binary tree, it has to follow the inorder traversal like the one before deleting it. No need to go through the whole alphabet
I drew it correctly in the diagram, but wrote it wrong underneath. Hopefully it's still clear from the markscheme after that, apologies for the confusion
hey. can you please make a video of Alevels 9618 Linked List and Binary Tree surrounding the kinds of question asked also can you please cover OOP(object oriented programming)
@@TheCSClassroom and also declarative programming, imperative programming and file codes(topic 20.2 of 9618) I understand your time is valuable and that you're making the best use if it. My Alevel's exams start in May and I was really hoping to cover the syllabus by mid April.
@@ahsannadeem9167 I'm working on Topic 13 at the moment, but after that I'll probably work on releasing Topic 20 in multiple parts (it's a huge topic).
18:15 for queues it should be FIFO

I'll try my best. I'm working on Option A at the moment, which I plan on releasing early next week.
@@TheCSClassroom you are god sent
omg dices arrows with pre,in, post order is so useful, I have never understand it so clearly
What is the function of pointers? I didn't quite understand

hi at timestamp 49.52. instead of elder the post order traversal should start with elm right. pls confirm
Can confirm. I did it correctly in the diagram, but wrote it incorrectly underneath. The correct order is also in the subsequent markscheme.
wallah you saved me, my mock tommorow and i left topic 5 to the last
wallah brotha, same
You got the order wrong for post order 49:34

@@TheCSClassroom no worries, its all good
love it!
Thank you so much!
36:20 you forgot the 8 I think
Yeah, I accidentally left it out in the 2nd version of the binary tree. Sorry for any confusion.
@@TheCSClassroom No worries!! I moved up from a 5 in cs to a 7 because of you!! thank you sm you're so underrated :>
wow

also can you please cover OOP(object oriented programming)
Yeah, I'll add it to the list.

Can you please do option c web science
Yes, my own class is doing Option C.
